[0035] In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.
[0036] The coexistence or integration of communication and perception functions is a key technology for next-generation mobile communication systems and a current research focus in academia and industry. Synaesthesia devices sample the propagation space by sending electromagnetic wave signals, enabling them to perceive their surroundings. Using these devices to sense micro-deformations has also become a major application area of interest in the industry. For example, a synaesthesia base station installed on a rooftop can monitor the operating status of nearby buildings, such as tilt, subsidence, and swaying. It can also be used to monitor the operating status of bridges, mines, road slopes, and mountainous terrain.
[0037] Synaesthesia equipment continuously monitors target observation points, enabling it to detect micro-deformations of objects. This monitoring process can be divided into three stages: acquiring deformation information, analyzing it, and predicting future deformation trends. In real-world environments, observed deformation information not only includes the deformation of the monitoring point itself but also includes observation errors caused by environmental factors such as noise and atmospheric conditions. These errors can affect the accuracy of deformation inversion at the monitoring point to varying degrees. Eliminating or reducing the impact of observation errors on the true degree of deformation at the inverted monitoring point and accurately perceiving the degree of deformation at the monitoring point are pressing technical challenges in this field.
[0038] Based on this, the embodiments of the present application provide a deformation perception method, apparatus, device, medium, and computer program product that can accurately perceive the degree of deformation of a monitoring point.
[0039] The embodiment of the present application first proposes a deformation perception method, which can be applied to a synesthesia device, which has the ability to send and receive carrier signals with an integrated waveform. See Figure 7, which shows a schematic diagram of the implementation environment of a deformation perception method. As shown in Figure 7, the deformation perception method can be applied to a base station (Base Station), which transmits a carrier signal with an integrated waveform to multiple target points in the observation area and receives echo signals from the target points. Through continuous observation of the target monitoring point, the echo signal sequence of the target monitoring point in the time dimension is received, the echo signal sequence is processed and analyzed, and the deformation degree of the target monitoring point is determined.
[0040] Please see FIG. 1 , which shows a deformation sensing method provided by an embodiment of the present application. As shown in FIG. 1 , the deformation sensing method includes but is not limited to steps S110 to S130 .
[0041] Step S110 , determining a first deformation characteristic value corresponding to the target monitoring point and a second deformation characteristic value corresponding to the reference point.
[0042] It can be understood that the target monitoring point and the reference point can be a target point on an object such as a mountain, a building or a bridge, wherein the reference point can be one or more, and the target monitoring point and the reference point can be on the same object. As shown in Figure 7, the target monitoring point is the highest point of building A, and the reference point is the lowest point of building A. The target monitoring point and the reference point can also be on different objects. As shown in Figure 8, the target monitoring point is in building A, and the reference point is in building B.
[0043] It should be noted that the first deformation eigenvalue is used to describe the deformation of the target monitoring point. The first deformation eigenvalue includes the status information of the target monitoring point itself, and also includes the observation error caused by environmental factors during the observation process; and the second deformation eigenvalue is used to describe the deformation of the reference point. Compared with the first deformation eigenvalue, the target point that has not been deformed in the observation area can be selected as the reference point, so that the second deformation eigenvalue of the reference point only includes the observation error caused by environmental factors during the observation process.
[0044] Step S120 : compensating the first deformation characteristic value according to the second deformation characteristic value to obtain a third deformation characteristic value corresponding to the target monitoring point.
[0045] It should be understood that the first deformation eigenvalue includes observation errors caused by environmental factors. If the deformation degree of the target monitoring point is inverted based on the first deformation eigenvalue, the deformation perception result will be inaccurate. Because the second deformation eigenvalue of the reference point only includes the observation errors caused by environmental factors during the observation process, after determining the first deformation eigenvalue corresponding to the target monitoring point and the second deformation eigenvalue corresponding to the reference point, the first deformation eigenvalue is compensated based on the second deformation eigenvalue to compensate for the impact of the observation error caused by environmental factors on the deformation perception accuracy, thereby obtaining the third deformation eigenvalue corresponding to the target monitoring point.
[0046] Step S130: determining the deformation degree of the target monitoring point according to the third deformation characteristic value.
[0047] It should be understood that compensating the first deformation eigenvalue of the target monitoring point according to the second deformation eigenvalue corresponding to the reference point effectively reduces the impact of the observation error on the inverted deformation information of the target monitoring point, and more accurately inverts the deformation degree of the target monitoring point based on the third deformation eigenvalue.
[0048] The deformation perception method provided in the embodiment of the present application first determines the first deformation characteristic value corresponding to the target monitoring point and the second deformation characteristic value corresponding to the reference point, and then compensates the first deformation characteristic value according to the second deformation characteristic value to obtain a third deformation characteristic value corresponding to the target monitoring point. The deformation degree of the target monitoring point is determined according to the third deformation characteristic value, and the first deformation characteristic value of the target monitoring point is compensated by the second deformation characteristic value of the reference point. This can effectively compensate for the influence of the observation error caused by the actual environment on the deformation degree of the inverted target monitoring point, and more accurately perceive the deformation degree of the target monitoring point.
[0049] In some embodiments, the reference point represents a target point that has not been deformed, and the reference point is selected by:
[0050] A target point that meets a preset scattering parameter threshold is selected in the target area as a reference point. The scattering parameter threshold includes at least one of an amplitude fluctuation threshold, a phase fluctuation threshold, and a coherence fluctuation threshold.
[0051] It should be understood that the reference point represents an undeformed target point. A target point that satisfies a preset scattering parameter threshold within the target area can be selected as the reference point. Specifically, a target point with stable scattering characteristics within the target area can be selected as the reference point, such as an exposed rock, a building corner, or other strong scatterer. The scattering parameter threshold includes at least one of an amplitude fluctuation threshold, a phase fluctuation threshold, and a coherence fluctuation threshold.
[0052] In the process of selecting a reference point, multiple rounds of carrier signals for selecting a reference point can be transmitted to the target area, and echo signal sequences reflected by various target points in the target area are received. Then, the scattering parameters of each echo signal in the echo signal sequence are analyzed, such as the amplitude fluctuation information, phase fluctuation information or coherence fluctuation information of the echo signal in the time dimension. Based on the scattering parameter analysis results, a target point with stable scattering characteristics is selected from the target area as a reference point. For example, it is determined whether at least one of the amplitude fluctuation, phase fluctuation and coherence fluctuation of the echo signal reflected by the target point in the time dimension is less than the corresponding scattering parameter threshold.
[0053] It should also be noted that in addition to selecting target points that meet the preset scattering parameter threshold in the target area as reference points, reflective devices such as radar corner reflectors can also be deployed in the observation area and the deployed reflective devices can be used as reference points.
[0054] In an embodiment of the present application, since the reference point is a target point that has not been deformed and has stable scattering characteristics during the deformation perception observation process, the echo signal of the reference point is relatively stable in the time dimension. Based on the deformation characteristic value of the reference point, it is convenient to compensate for the deformation characteristic value of the target monitoring point, and more accurate deformation information of the target monitoring point can also be obtained.
[0055] In some embodiments, please refer to Figure 3, which shows a schematic flow chart of the sub-steps of step S110 in Figure 1. As shown in Figure 3, the first deformation characteristic value corresponding to the target monitoring point and the second deformation characteristic value corresponding to the reference point are determined, including but not limited to steps S310 to S330.
[0056] Step S310: transmitting multiple rounds of carrier signals.
[0057] Step S320: monitoring echo signals corresponding to multiple rounds of carrier signals.
[0058] Step S330 : determining a first deformation characteristic value corresponding to the target monitoring point and a second deformation characteristic value corresponding to the reference point according to the multiple echo signals.
[0059] It should be understood that the deformation perception method can be applied to telepathic equipment with an integrated waveform transmission, such as a communication perception integrated base station. In the process of determining the first deformation characteristic value corresponding to the target monitoring point and the second deformation characteristic value corresponding to the reference point, the telepathic equipment first transmits multiple rounds of carrier signals to the area where the target monitoring point is located, and then monitors the echo signals corresponding to the multiple rounds of carrier signals, that is, the echo signals reflected by various target points in the area where the target monitoring point is located. By processing and analyzing the monitored multiple rounds of echo signals, the first deformation characteristic value corresponding to the target monitoring point and the second deformation characteristic value corresponding to the reference point are determined.
[0060] In a specific embodiment, the first deformation characteristic value is the phase difference of the echo signal reflected by the target monitoring point, and the second deformation characteristic value is the phase difference of the echo signal reflected by the reference point.
[0061] It is understandable that since the phase information of the echo signals reflected by the target monitoring point before and after deformation is different, the deformation information of the target monitoring point is obtained by inverting the phase changes of multiple rounds of echo signals. However, in the actual environment, the phase difference of the echo signal not only contains the state information of the target monitoring point itself, but also includes the phase error introduced by environmental factors such as noise and atmospheric medium in the actual environment. It needs to be compensated when analyzing the deformation degree of the target monitoring point to more accurately perceive the deformation degree of the target monitoring point. Among them, the phase error caused by noise can be compensated or reduced by improving the signal-to-noise ratio or filtering processing. The phase error caused by the atmosphere refers to the influence of the atmospheric medium under different time and space conditions, temperature, humidity and atmospheric pressure, etc. during the propagation of electromagnetic wave signals, which causes the atmospheric refractive index to change, resulting in the deflection of the propagation direction of the electromagnetic wave, and then causes the propagation time to be delayed. This phase error will be superimposed on the actual deformation phase of the target. The phase difference of the echo signal reflected by the target monitoring point is used as the first deformation characteristic value of the target monitoring point, and the phase difference of the echo signal reflected by the reference point is used as the second deformation characteristic value of the reference point. By using the second deformation characteristic value to compensate for the first deformation characteristic value, the influence of the phase error caused by the atmosphere on the deformation degree of the inversion monitoring point is compensated.
[0062] In addition, other signal characteristic information in the echo signal can be selected as the deformation characteristic value of the target monitoring point and the reference point to describe the deformation of the target monitoring point and the reference point, as long as the signal characteristic information changes with the deformation of the target monitoring point itself and can be used to invert the deformation degree of the target monitoring point.
[0063] In a specific embodiment, the deformation degree of the target monitoring point is measured by the deformation size d, and the third deformation characteristic value of the target monitoring point, that is, the actual deformation phase difference of the target monitoring point, is calculated. Determine the deformation degree of the target monitoring point. The deformation size d of the target monitoring point can be determined by formula (1):
[0064] Where λ is the wavelength of the carrier signal. If the carrier frequency of the carrier signal is f c , the corresponding wavelength is c / f c .
[0065] In some embodiments, please refer to Figure 4, which shows a sub-step flow chart of step S330 in Figure 3. As shown in Figure 4, based on multiple rounds of echo signals, the first deformation characteristic value corresponding to the target monitoring point and the second deformation characteristic value corresponding to the reference point are determined, including steps S410 to S430.
[0066] Step S410, for the echo signal corresponding to each round of carrier signal, determine the signal points corresponding to the target monitoring point and the reference point in the echo signal respectively according to the distance values corresponding to the target monitoring point and the reference point respectively, determine the first echo signal value according to the signal point corresponding to the target monitoring point, and determine the second echo signal value according to the signal point corresponding to the reference point.
[0067] Step S420 : determining a first deformation characteristic value according to a plurality of first echo signal values of a plurality of rounds of echo signals corresponding to the target monitoring point.
[0068] Step S430 : determining a second deformation characteristic value according to a plurality of second echo signal values of a plurality of rounds of echo signals corresponding to the reference point.
[0069] It is understood that, as shown in FIG8 , a beam of carrier signals transmitted by the base station can be used to simultaneously monitor a target monitoring point in building A and a reference point in building B. The deformation characteristic values of the target monitoring point and the reference point will be formed in the echo signal of the same beam. Therefore, in the echo signals corresponding to multiple rounds of carrier signals, for each round of carrier signals, the signal points corresponding to the target monitoring point and the reference point in the echo signal are determined based on the distance between the target monitoring point, the reference point, and the telepathic device. For example, the deformation characteristic value of the target monitoring point is formed at signal point A in the echo signal, while the deformation characteristic value of the reference point is formed at signal point B in the echo signal. Then, a first echo signal value of the target monitoring point is determined based on signal point A, and a second echo signal value of the reference point is determined based on signal point B. Finally, a first deformation characteristic value is determined based on the multiple first echo signal values of the multiple rounds of echo signals corresponding to the target monitoring point, and a second deformation characteristic value is determined based on the multiple second echo signal values of the multiple rounds of echo signals corresponding to the reference point.
[0070] In a specific embodiment, the first echo signal value and the second echo signal are phase values, the first deformation characteristic value is the phase difference of the echo signal reflected by the target monitoring point, and the second deformation characteristic value is the phase difference of the echo signal reflected by the reference point.
[0071] Specifically, according to the distance value between the target monitoring point and the reference point and the telepathic device, the signal point A corresponding to the target monitoring point and the signal point B corresponding to the reference point of the echo signal in the time domain are determined, and then the phase value α of the echo signal at signal point A and the phase value β of the echo signal at signal point B are obtained. According to the multiple phase values α in the multi-round echo signals corresponding to the target monitoring point, the phase difference of the echo signal reflected by the target monitoring point is determined, and according to the multiple phase values β in the multi-round echo signals corresponding to the reference point, the phase difference of the echo signal reflected by the reference point is determined.
[0072] In some embodiments, multiple rounds of carrier signals are transmitted, and echo signals corresponding to the multiple rounds of carrier signals are monitored, including: in each round of transmission, carrier signals of different frequencies are transmitted to multiple target points in the target area, and the multiple target points include target monitoring points and reference points.
[0073] It should be understood that the embodiment of the present application adopts frequency division multiple access to transmit carrier signals of different frequencies to multiple target points in the target area, wherein the multiple target points include target monitoring points and reference points. As shown in FIG7 , the base station transmits carrier signals of different frequencies to multiple target points in building A, and the frequencies are divided into f1, f2, ..., f n , where the target point at the bottom of the building is taken as the reference point, and the frequency of the carrier signal corresponding to the reference point is f n , taking the target point on the top of the building as the target monitoring point, the frequency of the carrier signal corresponding to the target monitoring point is f1. Therefore, when monitoring the echo signals corresponding to multiple rounds of carrier signals, the echo signals reflected by the target monitoring point and the reference point can be obtained by frequency division. Through down-conversion, filtering, and Fourier transform processing, the deformation characteristic values of the target monitoring point and the reference point can be obtained, and then the deformation degree of the target monitoring point can be determined.
[0074] In some embodiments, the frequency of the carrier signal transmitted to the target monitoring point is a first frequency, and the frequency of the carrier signal transmitted to the reference point is a second frequency.
[0075] Correspondingly, please refer to Figure 5, which shows a schematic diagram of the sub-step flow of step S330 in Figure 3. As shown in Figure 5, based on multiple rounds of echo signals, the first deformation characteristic value corresponding to the target monitoring point and the second deformation characteristic value corresponding to the reference point are determined, including steps S510 to S550.
[0076] Step S510 : Acquire an echo signal of a first frequency and an echo signal of a second frequency from echo signals corresponding to each round of carrier signals.
[0077] Step S520: For the echo signal of the first frequency obtained in each round of monitoring, determine the signal point corresponding to the target monitoring point in the echo signal of the first frequency according to the distance value corresponding to the target monitoring point, and determine the first echo signal value according to the signal point corresponding to the target monitoring point.
[0078] Step S530: For the echo signal of the second frequency obtained in each round of monitoring, determine the signal point corresponding to the reference point in the echo signal of the second frequency according to the distance value corresponding to the reference point, and determine the second echo signal value according to the signal point corresponding to the reference point.
[0079] Step S540 : determining a first deformation characteristic value according to a plurality of first echo signal values of the echo signals of the target monitoring point corresponding to a plurality of rounds of the first frequency.
[0080] Step S550 : determining a second deformation characteristic value according to a plurality of second echo signal values of a plurality of rounds of echo signals of a second frequency corresponding to the reference point.
[0081] It can be understood that frequency division multiple access is used to transmit carrier signals of different frequencies to multiple target points in the target area, and the frequencies are divided into f1, f2, ..., f n In the echo signals obtained in each round of monitoring, the scattering parameters of the echo signals are analyzed, for example, the amplitude fluctuation, phase fluctuation or coherence fluctuation of the echo signals in the time dimension are analyzed, and based on the analysis results, the target points with stable scattering characteristics in the target area are regarded as reference points. For example, by judging whether at least one of the amplitude fluctuation, phase fluctuation and coherence fluctuation of the echo signal reflected by the target point in the time dimension is less than the corresponding scattering parameter threshold, it is determined whether the target point can be used as a reference point, and then the frequencies of the echo signals reflected by the target monitoring point and the reference point are distinguished. For example, the first frequency of the echo signal reflected by the target monitoring point is f1, and the second frequency of the echo signal reflected by the reference point is f n Finally, the echo signal of the first frequency f1 reflected by the target monitoring point and the second frequency f reflected by the reference point are obtained by frequency division. n echo signal.
[0082] The echo signal of the first frequency f1 is the echo signal reflected by the target monitoring point. Therefore, for the echo signal of the first frequency f1 obtained in each round of monitoring, the signal point corresponding to the target monitoring point in the echo signal of the first frequency f1 is determined according to the distance value between the target monitoring point and the telepathic device, and then the first echo signal value is determined according to the signal point corresponding to the target monitoring point.
[0083] The second frequency f n The echo signal is the echo signal reflected from the reference point. Therefore, for each round of monitoring, the second frequency f nThe echo signal of the reference point is determined according to the distance between the reference point and the telepathic device. n The corresponding signal point in the echo signal of the reference point is determined, and then the second echo signal value is determined according to the washed point corresponding to the reference point.
[0084] Finally, the first deformation characteristic value is determined based on multiple first echo signal values of the target monitoring point corresponding to multiple rounds of echo signals of the first frequency, and the second deformation characteristic value is determined based on multiple second echo signal values of the reference point corresponding to multiple rounds of echo signals of the second frequency.
[0085] In a specific embodiment, the first echo signal value and the second echo signal are phase values, the first deformation characteristic value is the phase difference of the echo signal reflected by the target monitoring point, and the second deformation characteristic value is the phase difference of the echo signal reflected by the reference point.
[0086] Specifically, according to the distance value between the target monitoring point and the synesthesia device, the echo signal of the first frequency is determined to correspond to the signal point A of the target monitoring point at the time domain level. According to the distance value between the reference point and the synesthesia device, the echo signal of the second frequency is determined to correspond to the signal point B of the reference point at the time domain level. Then, the phase value α of the echo signal of the first frequency at signal point A and the phase value β of the echo signal of the second frequency at signal point B are determined. According to the multiple phase values α of the multiple rounds of the echo signal of the first frequency corresponding to the target monitoring point, the phase difference of the echo signal of the first frequency reflected by the target monitoring point is determined. According to the multiple phase values β in the multiple rounds of the echo signal of the second frequency corresponding to the reference point, the phase difference of the echo signal of the second frequency reflected by the reference point is determined.
[0087] In some embodiments, the reference point is located in the target area where the target monitoring point is located.
[0088] Correspondingly, compensating the first deformation characteristic value according to the second deformation characteristic value to obtain a third deformation characteristic value corresponding to the target monitoring point includes: subtracting the second deformation characteristic value from the first deformation characteristic value to obtain the third deformation characteristic value corresponding to the target monitoring point.
[0089] It is understandable that the reference point is located in the target area where the target monitoring point is located, indicating that the reference point and the target monitoring point are in a similar environment, and the effects of environmental factors such as the atmospheric medium on the deformation perception of the target monitoring point and the reference point are approximately the same. Specifically, it is possible to determine whether the reference point is located in the target area where the target monitoring point is located based on the position information such as the distance and direction of the reference point relative to the target monitoring point. The target area can be a spherical, square or irregular area centered on the target monitoring point, and its size can be determined by the actual environment where the target monitoring point is located; or, based on the environmental information in the observation scene, the observation area is divided into different target areas, and the same target area has a similar environment. When the reference point is located in the target area where the target monitoring point is located, it is considered that the reference point and the target monitoring point are in a similar environment, that is, the temperature, humidity and atmospheric pressure in the environment are considered to be approximately the same.
[0090] It should be noted that the echo signal reflected by the target monitoring point will be affected by the deformation of the target monitoring point itself and by environmental factors. When the reference point is located in the target area where the target monitoring point is located, it is considered that the reference point and the target monitoring point are in a similar environment, that is, the echo signals reflected by the reference point and the target monitoring point are affected by the same environmental factors. From the above, it can be seen that the first deformation eigenvalue includes the state information of the target monitoring point due to itself, and also includes the observation error caused by the influence of environmental factors during the observation process, while the second deformation eigenvalue only includes the observation error caused by the influence of environmental factors during the observation process. It is considered that the observation errors corresponding to the reference point and the target monitoring point are the same. By subtracting the second deformation eigenvalue from the first deformation eigenvalue, the influence of the observation error caused by environmental factors on the deformation degree of the inverted target monitoring point can be compensated to obtain the third deformation eigenvalue corresponding to the target monitoring point.
[0091] When the first deformation characteristic value is the phase difference of the echo signal reflected by the target monitoring point, and the second deformation characteristic value is the phase difference of the echo signal emitted by the reference point, the phase information in the echo signal not only contains the state information of the target point itself, but also includes phase errors introduced by noise, atmospheric media, and other factors in the actual environment. On the one hand, during the deformation perception observation process, the phase error caused by noise in the echo signal can be minimized by maintaining a good signal-to-noise ratio in the observation area or through filtering. On the other hand, since the reference point is located in the target area where the target monitoring point is located, it can be assumed that the environmental conditions of the reference point and the target monitoring point are similar, that is, the temperature, humidity, and atmospheric pressure are approximately the same. In other words, the phase error caused by the atmosphere in the echo signals reflected by the reference point and the target monitoring point is the same. Therefore, the third deformation characteristic value corresponding to the target monitoring point can be obtained by subtracting the second deformation characteristic value of the reference point from the first deformation characteristic value of the target monitoring point to compensate for the impact of the phase error caused by the atmosphere on the deformation perception accuracy of the target monitoring point.
[0092] For example, the phase difference of the echo signal reflected by the target monitoring point in the time dimension is It can be expressed as follows by formula (2):
[0093] in, Indicates the phase error caused by deformation in the echo signal reflected from the target monitoring point. It represents the phase error caused by noise in the echo signal reflected from the target monitoring point. It represents the phase error caused by the atmosphere in the echo signal reflected from the target monitoring point.
[0094] Phase difference of the echo signal reflected from the reference point in the time dimension It can be expressed as follows by formula (3):
[0095] in, Indicates the phase error caused by noise in the echo signal reflected from the reference point. Indicates the phase error caused by the atmosphere in the echo signal reflected from the reference point.
[0096] During the deformation perception observation process, the noise phase error in the echo signal can be reduced as much as possible by maintaining a good signal-to-noise ratio in the observation area or by filtering. and Therefore, the influence of noise phase error can be ignored and only the atmospheric phase error is considered. and impact.
[0097] At the same time, the reference point is located in the target area where the target monitoring point is located. It can be considered that the environmental conditions of the reference point and the target monitoring point are similar, that is, the temperature, humidity and atmospheric pressure are approximately the same, and the influence of the atmosphere on the deformation perception observation of the target monitoring point and the reference point is the same, that is, and Therefore, the atmospheric phase error of the reference point can be used to compensate the atmospheric phase error of the target monitoring point to obtain the third deformation eigenvalue corresponding to the target monitoring point, that is, the true deformation phase at the deformation point, and the third deformation eigenvalue of the target monitoring point. It can be calculated by formula (4):
[0098] In a specific embodiment, the reference point is located in the target area where the target monitoring point is located, and the deformation characteristic values of the reference point and the target monitoring point are formed in the echo signal of the same beam. As shown in Figure 8, a beam of carrier signals transmitted by the base station can be used to simultaneously monitor the target monitoring point in building A and the reference point in building B. According to the distance value between the target monitoring point, the reference point and the telepathic device, the first deformation characteristic value corresponding to the target monitoring point and the second deformation characteristic value corresponding to the reference point are determined from the echo signal.
[0099] In one specific embodiment, the reference point is located in the target area where the target monitoring point is located, and in each round of carrier signal transmission, carrier signals of different frequencies are transmitted to the reference point and the target monitoring point. As shown in Figure 7, the base station transmits a carrier signal of a first frequency to the target monitoring point and a carrier signal of a second frequency to the reference point. From the echo signals corresponding to the monitoring carrier signals, the base station obtains the echo signal of the first frequency reflected by the target monitoring point and the echo signal of the second frequency reflected by the reference point in a frequency division manner. The first deformation characteristic value of the target monitoring point is determined from the echo signal of the first frequency, and the second deformation characteristic value of the reference point is determined from the echo signal of the second frequency.
[0100] In some embodiments, the number of reference points is multiple.
[0101] Correspondingly, please refer to Figure 2, which shows a schematic diagram of the sub-step process of step S120 in Figure 1. As shown in Figure 2, the first deformation characteristic value is compensated according to the second deformation characteristic value to obtain a third deformation characteristic value corresponding to the target monitoring point, including but not limited to steps S210 to S240.
[0102] Step S210: Obtain distance values corresponding to multiple reference points.
[0103] Step S220 , performing fitting processing on the second deformation feature values and distance values corresponding to the plurality of reference points to obtain a target fitting function.
[0104] Step S230 : determining a target compensation value according to the target fitting function and the distance value corresponding to the target monitoring point.
[0105] Step S240 : subtracting the target compensation value from the first deformation characteristic value to obtain a third deformation characteristic value corresponding to the target monitoring point.
[0106] It should be understood that if a reference point cannot be found within the target area where the target monitoring point is located, multiple reference points can be selected within the observation area, and the first deformation characteristic value can be compensated based on the second deformation characteristic values corresponding to the multiple reference points to obtain a third deformation characteristic value corresponding to the target monitoring point. For example, as shown in FIG9 , the reference points include reference point 1, reference point 2, and reference point 3, where reference point 1 is located at mountain A, reference point 2 is located at mountain B, and reference point 3 is located at building B.
[0107] Since the environment in which the reference point is located may be inconsistent with the environment in which the target monitoring point is located, the observation error caused by environmental factors in the second deformation eigenvalue of the reference point may be inconsistent with that of the target monitoring point. Therefore, it is necessary to first fit the second deformation eigenvalues and distance values corresponding to multiple reference points to obtain a target fitting function, determine the relationship between the observation error from the target monitoring point and the observation error from the reference point, then determine a target compensation value based on the target fitting function and the distance value corresponding to the target monitoring point, and then subtract the compensation value from the first deformation eigenvalue to completely compensate for the observation error of the target monitoring point to obtain a third deformation eigenvalue corresponding to the target monitoring point. By fitting the relationship between the deformation eigenvalue and the distance of each reference point and further inferring the target compensation value of the target monitoring point, that is, inferring the observation error caused by environmental factors in the first deformation eigenvalue of the target monitoring point, the first deformation eigenvalue including the state information of the target monitoring point itself and the observation error caused by environmental factors is subtracted from the target compensation value to obtain the true deformation eigenvalue of the target monitoring point.
[0108] When the first deformation characteristic value is the phase difference of the echo signal reflected by the target monitoring point, and the second deformation characteristic value is the phase difference of the echo signal emitted by the reference point, the phase error caused by noise is ignored, and the phase difference of the reference point only includes the phase error caused by the atmosphere. By establishing a polynomial relationship between the atmospheric phase error and the distance of each reference point, the influence of the atmospheric phase error is fitted, and the atmospheric phase error in the phase difference corresponding to the target monitoring point is inferred.
[0109] Specifically, the phase difference of the echo signal reflected by the target monitoring point in the time dimension It can be expressed as follows by formula (5):
[0110] in, Indicates the phase error caused by deformation in the echo signal reflected from the target monitoring point. is the phase error caused by the atmosphere in the echo signal reflected from the target monitoring point, It is calculated from the polynomial relationship between the atmospheric phase error and the distance of the reference point. The phase difference corresponding to the target monitoring point Subtract the estimated atmospheric phase error The true deformation phase of the target monitoring point can be obtained

As shown in Figure 9, the base station transmits a carrier signal with a frequency of f1 to the target monitoring point, a carrier signal with a frequency of f2 to reference point 1, and a carrier signal with a frequency of f3 to reference point 2. From the echo signals corresponding to the monitoring carrier signals, the echo signal with a frequency of f1 reflected by the target monitoring point, the echo signal with a frequency of f2 reflected by reference point 1, and the echo signal with a frequency of f3 reflected by reference point 2 are obtained by frequency division. The first deformation characteristic value of the target monitoring point is determined from the echo signal with a frequency of f1, the second deformation characteristic value of reference point 1 is determined from the echo signal with a frequency of f2, and the second deformation characteristic value of reference point 2 is determined from the echo signal with a frequency of f3. Furthermore, the distance values corresponding to reference point 1 and reference point 2 are obtained, and the second deformation characteristic values and distance values corresponding to reference point 1 and reference point 2 are fitted to obtain the target fitting function. According to the target fitting function and the distance value corresponding to the target monitoring point, the target compensation value is determined, and the target compensation value is subtracted from the first deformation characteristic value to obtain the third deformation characteristic value corresponding to the target monitoring point.

Simultaneously, the carrier signal with a frequency of f1 is also used to monitor reference point 3. That is, the beams corresponding to the target monitoring point and reference point 3 have the same carrier frequency. From the echo signals corresponding to the monitoring carrier signals, the echo signal with a frequency of f1, the echo signal with a frequency of f2 reflected from reference point 1, and the echo signal with a frequency of f3 reflected from reference point 2 are obtained by frequency division. The first deformation characteristic value of the target monitoring point and the second deformation characteristic value of reference point 3 are determined from the echo signal with a frequency of f1 based on the distance between the target monitoring point, reference point 3, and the base station. A second deformation eigenvalue of reference point 1 is determined from the echo signal at frequency f2, and a second deformation eigenvalue of reference point 2 is determined from the echo signal at frequency f3. Furthermore, distance values corresponding to reference points 1, 2, and 3 are obtained, and the second deformation eigenvalues and distance values corresponding to reference points 1, 2, and 3 are fitted to obtain a target fitting function. A target compensation value is determined based on the target fitting function and the distance value corresponding to the target monitoring point. The target compensation value is subtracted from the first deformation eigenvalue to obtain a third deformation eigenvalue corresponding to the target monitoring point.
