[0002] The location generation method is a method for generating the location of a target radar. The typical approach to generating the target radar location is as follows: First, acquire the currently acquired intermediate frequency (IF) signal. Second, manually compare the currently acquired IF signal with historically acquired IF signals for each azimuth angle to obtain the azimuth angle of the currently acquired IF signal. Finally, send the azimuth angle of the currently acquired IF signal to relevant reconnaissance equipment for location reconnaissance to determine the location of the target radar emitting the currently acquired IF signal.

[0003] However, the inventors discovered that when using the above method to generate target radar positions, the following technical problems often arise:

[0004] First, comparing the currently acquired intermediate frequency (IF) signal with the historical IF signals acquired at each of the multiple azimuth angles will result in low efficiency in identifying the azimuth angle.

[0005] Second, when reconnaissance equipment is conducting location reconnaissance, the target radar may detect the reconnaissance equipment, making the use of reconnaissance equipment for location reconnaissance not very safe.

[0006] The information disclosed in this background section is only intended to enhance the understanding of the background of the inventive concept, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] The summary portion of this disclosure is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description portion. This summary portion is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0008] Some embodiments of this disclosure provide location generation methods, apparatuses, devices, computer-readable media, and program products to address one or more of the technical problems mentioned in the background section above.

[0009] In a first aspect, some embodiments of this disclosure provide a location generation method, the method comprising: acquiring an intermediate frequency (IF) signal emitted by a target radar; quantizing the IF signal to obtain an IF signal vector; inputting the IF signal vector into a pre-trained azimuth recognition model to obtain an azimuth angle; generating a velocity corresponding to a reflected IF signal and a first duration for the reflected IF signal based on the azimuth angle, wherein the first duration is the time from the time point of transmitting the IF signal to the time point of receiving the reflected IF signal; and generating the location of the target radar based on the velocity and the first duration.

[0010] Secondly, some embodiments of this disclosure provide a position generation apparatus, the apparatus comprising: an acquisition unit configured to acquire an intermediate frequency (IF) signal emitted by a target radar; a quantization processing unit configured to quantize the IF signal to obtain an IF signal vector; an input unit configured to input the IF signal vector into a pre-trained azimuth recognition model to obtain an azimuth angle; a first generation unit configured to generate a velocity corresponding to a reflected IF signal and a first duration for the reflected IF signal based on the azimuth angle, wherein the first duration is the duration from the time point of transmitting the IF signal to the time point of receiving the reflected IF signal; and a second generation unit configured to generate the position of the target radar based on the velocity and the first duration.

[0011] Thirdly, some embodiments of this disclosure provide an electronic device, including: one or more processors; and a storage device having one or more programs stored thereon, wherein when the one or more programs are executed by the one or more processors, the one or more processors implement the method described in any implementation of the first aspect above.

[0012] Fourthly, some embodiments of this disclosure provide a computer-readable medium having a computer program stored thereon, wherein the program, when executed by a processor, implements the method described in any of the implementations of the first aspect above.

[0013] Fifthly, some embodiments of this disclosure provide a computer program product, including a computer program that, when executed by a processor, implements the method described in any of the implementations of the first aspect above.

[0014] The above embodiments of this disclosure have the following beneficial effects: the position generation method of some embodiments of this disclosure can improve the efficiency of azimuth angle identification. Specifically, the reason for the low efficiency of azimuth angle identification is that comparing the currently acquired intermediate frequency (IF) signal with the historically acquired IF signals of each azimuth angle, and comparing them one by one with the historically acquired IF signals of each of multiple azimuth angles, leads to low efficiency in azimuth angle identification. Based on this, the position generation method of some embodiments of this disclosure is as follows: First, acquire the IF signal emitted by the target radar; second, quantize the IF signal to obtain an IF signal vector; wherein, the acquired IF signal emitted by the radar cannot be input into the pre-trained azimuth angle identification model, and the IF signal needs to be quantized to obtain an IF signal vector before it can be input into the pre-trained azimuth angle identification model. Then, input the IF signal vector into the pre-trained azimuth angle identification model to obtain the azimuth angle; here, the acquired IF signal is quantized and then input into the pre-trained azimuth angle identification model to obtain the azimuth angle. This avoids the need to individually compare each intermediate frequency (IF) signal acquired at each historical azimuth angle, thereby improving the efficiency of azimuth angle identification. Next, using the aforementioned azimuth angle, a velocity corresponding to the reflected IF signal and a first duration for the reflected IF signal are generated. This first duration is the time from the time the IF signal is transmitted to the time the reflected IF signal is received. A radio frequency (RF) signal can be transmitted in the direction of the aforementioned azimuth angle to obtain the time point of the transmitted RF signal. In response to determining the location of the transmitted RF signal at a preset device, the transmitted RF signal is reflected. The receiver is controlled to receive the reflected RF signal, so that the receiver converts the received and reflected RF signal into an IF signal, obtaining the time point of receiving the reflected RF signal and the velocity corresponding to the reflected RF signal. The time point of receiving the reflected RF signal is determined as the time point of receiving the reflected IF signal, the velocity corresponding to the reflected RF signal is determined as the velocity corresponding to the reflected IF signal, and the time point of transmitting the RF signal is determined as the time point of transmitting the IF signal. The time interval between the time point of transmitting the intermediate frequency (IF) signal and the time point of receiving the reflected IF signal is determined as the first duration of the radio frequency (RF) signal. Finally, the position of the target radar is generated using the velocity and the first duration. In this embodiment, the acquired IF signal is quantized to obtain an IF signal vector, which is then input into a pre-trained azimuth recognition model. This avoids the need to individually compare the IF signals acquired historically for each of the multiple azimuth angles, thereby improving the efficiency of azimuth recognition.

[0024] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Figure 1A flow 100 of some embodiments of the location generation method according to the present disclosure is shown. The flow 100 of the location generation method includes the following steps:

[0026] Step 101: Acquire the intermediate frequency signal transmitted by the target radar.

[0027] In some embodiments, the entity executing the location generation method (e.g., an electronic device) can acquire the intermediate frequency signal emitted by the target radar via a wired or wireless connection. The target radar can represent the radar to be located. For example, the electronic device can be a first radar device.

[0028] Step 102: Quantize the intermediate frequency signal to obtain the intermediate frequency signal vector.

[0029] In some embodiments, the execution entity may perform quantization processing on the intermediate frequency (IF) signal to obtain an IF signal vector. The IF signal vector can represent the vector of the IF signal. The quantization processing may be signal quantization processing.

[0030] As an example, the above quantization process of the intermediate frequency signal to obtain the intermediate frequency signal vector may include the following steps:

[0031] The first step is to determine the sequence of ordinate values ​​corresponding to the above intermediate frequency (IF) signal in the frequency domain as an m-row, n-column IF signal value matrix. Here, m can be one, and n can be the number of abscissas corresponding to the above IF signal in the frequency domain.

[0032] The second step is to transform the intermediate frequency (IF) signal value matrix to obtain the IF signal vector. This transformation can be done by converting the IF signal matrix into an a-row, b-column matrix as the IF signal vector. The product of a and b is equal to the product of m and n.

[0033] Step 103: Input the intermediate frequency signal vector into the pre-trained azimuth recognition model to obtain the azimuth angle.

[0034] In some embodiments, the executing entity can input the intermediate frequency signal vector into a pre-trained azimuth angle recognition model to obtain the azimuth angle. The azimuth angle can be the azimuth angle of the target radar's location relative to the corresponding position of the executing entity. The pre-trained azimuth angle recognition model can be a model that identifies the azimuth angle of the target radar relative to the executing entity.

[0035] In some optional implementations of certain embodiments, the pre-trained azimuth recognition model described above can be generated through the following steps:

[0036] The first step is to acquire training samples. These training samples include training data and training labels. The training data can be the intermediate frequency (IF) signal emitted by the target radar. The training labels can be the azimuth angles of the executing entity in various directions. The training data can be the IF signal acquired by the executing entity from the direction of the azimuth angle.

[0037] The second step, using the acquired training samples, is to perform the following determination steps:

[0038] The first sub-step involves inputting the training data, including the training samples mentioned above, into the first convolutional layer of the initial azimuth recognition model to obtain the first training feature vector. The initial azimuth recognition model further includes a second convolutional layer and a fully connected layer.

[0039] The second sub-step involves inputting the first training feature vector into the second convolutional layer to obtain the second training feature vector.

[0040] The third sub-step involves inputting the second training feature vector into the fully connected layer to obtain the azimuth angle.

[0041] The fourth sub-step involves determining that the error between the aforementioned azimuth angle and the aforementioned training label is less than a preset error value. The initial azimuth angle recognition model is then trained and identified as the pre-trained azimuth angle recognition model. For example, the preset error value could be 0.4.

[0042] Optionally, after performing the following determination steps using the obtained training samples, the aforementioned execution entity may also perform the following steps:

[0043] In response to the fact that the error in determining the azimuth angle and the training labels included in the training samples is greater than or equal to the preset error value, the initial azimuth angle recognition model training is not completed. The parameters in the initial azimuth angle recognition model are adjusted, and the azimuth angle recognition model after parameter adjustment is used as the initial azimuth angle recognition model. Training samples are then acquired again to perform the determination step again.

[0044] Step 104: Generate the velocity corresponding to the reflected intermediate frequency signal and the first duration for the reflected intermediate frequency signal using the azimuth angle.

[0045] In some embodiments, the executing entity can generate a velocity corresponding to the reflected intermediate frequency (IF) signal and a first duration for the reflected IF signal based on the azimuth angle. The first duration can be the time from the point of transmitting the IF signal to the point of receiving the reflected IF signal. The velocity corresponding to the reflected IF signal can be the velocity of the IF signal transmitted by the executing entity to the target radar.

[0046] In practice, the aforementioned executing entity can generate a velocity corresponding to the reflected intermediate frequency signal and a first duration for the reflected intermediate frequency signal based on the aforementioned azimuth angle, which may include the following steps:

[0047] The first step is for the aforementioned executing entity to transmit a radio frequency signal in the direction of the aforementioned azimuth angle, thereby obtaining the time point of the transmitted radio frequency signal.

[0048] The second step involves reflecting the transmitted radio frequency signal in response to the location of the preset device.

[0049] The third step involves controlling the receiver to receive the reflected radio frequency (RF) signal, so that the receiver can convert the received and reflected RF signal into an intermediate frequency (IF) signal, thereby obtaining the time point at which the reflected RF signal was received and the corresponding velocity. The preset location can be a device in the direction of the aforementioned azimuth angle. For example, the preset device can be the aforementioned target radar.

[0050] The fourth step is to determine the time point at which the reflected radio frequency signal is received as the time point at which the reflected intermediate frequency signal is received, to determine the speed corresponding to the reflected radio frequency signal as the speed corresponding to the reflected intermediate frequency signal, and to determine the time point at which the radio frequency signal is transmitted as the time point at which the intermediate frequency signal is transmitted.

[0051] The fifth step is to determine the first duration of the radio frequency signal as the time from the time point of transmitting the intermediate frequency signal to the time point of receiving the reflected intermediate frequency signal.

[0052] In some optional implementations of certain embodiments, the execution entity can generate a velocity corresponding to the reflected intermediate frequency signal and a first duration for the reflected intermediate frequency signal based on the azimuth angle, which may include the following steps:

[0053] The first step is to transmit an intermediate frequency signal in the direction of the aforementioned azimuth angle to obtain the time point of transmission of the intermediate frequency signal.

[0054] The second step involves receiving the reflected intermediate frequency (IF) signal to obtain the time point at which the reflected IF signal was received and the corresponding velocity. The reflected IF signal is the result of the transmitted IF signal being reflected and received from the location of the target radar.

[0055] The third step is to determine the duration from the time point when the intermediate frequency signal is transmitted to the time point when the reflected intermediate frequency signal is received as the first duration of the intermediate frequency signal.

[0056] Step 105: Generate the target radar position using the speed and the first duration.

[0057] In some embodiments, the aforementioned executing entity can generate the position of the aforementioned target radar using the aforementioned speed and the aforementioned first duration.

[0058] In practice, the aforementioned executing entity can generate the location of the aforementioned target radar using the aforementioned speed and the aforementioned first duration, which may include the following steps:

[0059] The first step is to determine half of the product of the aforementioned speed and the aforementioned first duration as the first distance. This first distance can be the distance between the aforementioned executing entity and the aforementioned target radar.

[0060] The second step involves inputting the azimuth direction and the first distance into a trigonometric function formula to generate a first lateral distance and a first longitudinal distance. For example, the trigonometric function formula could be a double-angle formula. The first lateral distance can be the distance between the lateral coordinates of the target radar and the lateral coordinates of the executing entity. The first longitudinal distance can be the distance between the longitudinal coordinates of the target radar and the longitudinal coordinates of the executing entity.

[0061] The third step is to add the lateral coordinates of the aforementioned executing entity to the aforementioned first lateral distance to obtain the first lateral coordinates of the aforementioned target radar, and to add the longitudinal coordinates of the aforementioned executing entity to the aforementioned first longitudinal distance to obtain the first longitudinal coordinates of the aforementioned target radar.

[0062] The fourth step is to determine the position of the target radar by its first lateral coordinate and first longitudinal coordinate.

[0063] In some optional implementations of certain embodiments, the execution entity can generate the position of the target radar based on the speed and the first duration, which may include the following steps:

[0064] The first step is to determine half of the product of the aforementioned speed and the aforementioned first duration as the first distance. This first distance can be the distance between the aforementioned executing entity and the aforementioned target radar.

[0065] The second step is to generate the first position coordinates of the target radar based on the aforementioned azimuth angle and the aforementioned first distance.

[0066] In practice, the aforementioned executing entity can generate the first position coordinates of the target radar based on the aforementioned azimuth angle and the aforementioned first distance, which may include the following steps:

[0067] The first sub-step involves inputting the direction of the aforementioned azimuth angle and the aforementioned first distance into the aforementioned trigonometric function formula to generate the first lateral distance and the first longitudinal distance.

[0068] The second sub-step involves adding the lateral coordinates of the aforementioned executing entity to the aforementioned first lateral distance to obtain the first lateral coordinates of the aforementioned target radar, and adding the longitudinal coordinates of the aforementioned executing entity to the aforementioned first longitudinal distance to obtain the first longitudinal coordinates of the aforementioned target radar.

[0069] The third sub-step involves determining the first lateral coordinate and the first longitudinal coordinate of the target radar as the first position coordinates of the target radar.

[0070] The third step involves sending the first position coordinates of the target radar to a preset position determining device, which then generates the target radar's position. This preset position determining device can be a device that determines the first position coordinates of the target radar. For example, the preset position determining device can be a second radar device. The target radar's position is generated through the following steps:

[0071] The first sub-step involves receiving the first position coordinates of the target radar.

[0072] The second sub-step involves transmitting the aforementioned intermediate frequency signal of velocity in the direction of the azimuth angle corresponding to the first position coordinates of the aforementioned target radar, thereby obtaining the time point at which the aforementioned preset position determining device transmits the intermediate frequency signal.

[0073] The third sub-step involves determining the time point at which the intermediate frequency signal transmitted by the predetermined location is received, in response to the reflection of the determined intermediate frequency signal.

[0074] The fourth sub-step involves determining the time point at which the aforementioned preset location determining device transmits the intermediate frequency signal as the first time point, and determining the time point at which the aforementioned preset location determining device transmits the intermediate frequency signal as the second time point.

[0075] The fifth sub-step is to determine the duration from the first time point to the second time point as the second duration of the intermediate frequency signal.

[0076] The sixth sub-step involves determining half of the product of the aforementioned speed and the aforementioned second duration as the second distance. This second distance can be the distance between the aforementioned preset position determining device and the aforementioned target radar.

[0077] The seventh sub-step involves generating the second position coordinates of the target radar based on the azimuth angle corresponding to the first position coordinates of the target radar and the second distance.

[0078] In practice, generating the second position coordinates of the target radar based on the azimuth angle corresponding to the first position coordinates of the target radar and the second distance can include the following steps:

[0079] The first step involves inputting the direction of the azimuth angle corresponding to the first position coordinates of the target radar and the second distance into the trigonometric function formula to generate a second lateral distance and a second longitudinal distance. The second lateral distance can be the distance between the lateral coordinates of the preset position determining device and the lateral coordinates of the executing entity. The second longitudinal distance can be the distance between the longitudinal coordinates of the preset position determining device and the longitudinal coordinates of the preset position determining device.

[0080] The second step is to add the lateral coordinates of the preset position determining device and the second lateral distance to obtain the second lateral coordinates of the target radar, and to add the longitudinal coordinates of the preset position determining device and the second longitudinal distance to obtain the second longitudinal coordinates of the target radar.

[0081] The third step is to determine the second lateral coordinate and the second longitudinal coordinate of the target radar as the second position coordinate of the target radar.

[0082] The eighth sub-step involves, in response to determining that the first position coordinate is equal to the second position coordinate, arbitrarily selecting one of the two position coordinates as the position of the target radar.

[0083] The above-mentioned content, as an inventive point of this disclosure, solves the second technical problem mentioned in the background art: "When a reconnaissance device conducts position reconnaissance, the target radar may detect the reconnaissance device, making the security of using the reconnaissance device for position reconnaissance low." The factors contributing to the low security of using reconnaissance devices for position reconnaissance are often as follows: the target radar may detect the reconnaissance device. Solving these factors can achieve a high accuracy rate for determining the danger level. To achieve this effect, firstly, half of the product of the speed and the first duration is determined as the first distance. The first distance can be the distance between the executing entity and the target radar. Secondly, the first position coordinates of the target radar are generated based on the azimuth angle and the first distance. The trigonometric function formula can generate the first position coordinates of the target radar using the azimuth angle and the first distance. Finally, the first position coordinates of the target radar are sent to a preset position determining device, which then generates the position of the target radar. The preset position determining device can be a device for determining the first position coordinates of the target radar. For example, the preset position determining device can be a second radar device. The position of the target radar is generated through the following steps: First, the first position coordinates of the target radar are received. Second, an intermediate frequency (IF) signal of the aforementioned velocity is transmitted in the direction of the azimuth angle corresponding to the first position coordinates of the target radar, thereby obtaining the time point at which the preset position determining device transmits the IF signal. Third, in response to the determined transmission of the IF signal, the time point at which the IF signal transmitted by the preset position determining device is received is determined. Fourth, the time point at which the IF signal transmitted by the preset position determining device is transmitted is determined as the first time point, and the time point at which the IF signal received by the preset position determining device is received is determined as the second time point. Fifth, the duration from the first time point to the second time point is determined as the second duration of the IF signal. Sixth, half of the product of the aforementioned velocity and the second duration is determined as the second distance. The second distance may be the distance between the preset position determining device and the target radar. Seventh, based on the azimuth angle corresponding to the first position coordinates of the target radar and the second distance, the second position coordinates of the target radar are generated. Eighth, in response to determining that the first position coordinates are equal to the second position coordinates, one of the two position coordinates is arbitrarily selected as the position of the target radar. First, the first position coordinates of the target radar can be generated using the aforementioned azimuth angle and the first distance. Second, the first position coordinates of the target radar are determined by the aforementioned preset position determination device to obtain the second position coordinates of the target radar. Finally, in response to the determination that the first position coordinates are equal to the second position coordinates, one of the two position coordinates is arbitrarily selected as the position of the target radar.This can improve the accuracy of the target radar's location and also prevent the target radar from detecting it, thereby improving security.

[0084] Optionally, after selecting one of the two location coordinates as the location of the target radar, the executing entity may further perform the following steps:

[0085] In response to the determination that the first position coordinates are not equal to the second position coordinates, the second position coordinates are determined as the position of the target radar.

[0086] Optionally, after step 105, the aforementioned executing entity may also perform the following steps:

[0087] The aforementioned location is transmitted to an electronic jamming device, which then interferes with the target radar. The jamming device can be any device designed to interfere with the target radar. For example, the jamming device can be an electronic jammer.

[0088] Optionally, after step 105, the aforementioned executing entity may also perform the following steps:

[0089] The first step is to intercept the intermediate frequency signal received by the target radar.

[0090] The second step is to identify the intermediate frequency (IF) signal received by the target radar as described above, thereby obtaining the content of the IF signal received by the target radar. The content of the IF signal received by the target radar can be any content of the IF signal received by the target radar. The identification process can involve sending the IF signal received by the target radar to a preset IF signal identification model to generate the content of the IF signal received by the target radar.

[0091] As an example, the aforementioned preset intermediate frequency signal recognition model may include, but is not limited to, one of the following: FCN (Fully Convolutional Networks) model, ResNet (Residual Network) model, or GoogLeNet (Deep Neural Network) model.

[0092] The third step is to send the identified information to the propagation terminal connected to the executing entity, so that the propagation terminal can propagate the identified information. The propagation terminal can be a terminal that receives and propagates information.

[0093] The above embodiments of this disclosure have the following beneficial effects: the position generation method of some embodiments of this disclosure can improve the efficiency of azimuth angle identification. Specifically, the reason for the low efficiency of azimuth angle identification is that comparing the currently acquired intermediate frequency (IF) signal with the historically acquired IF signals of each azimuth angle, and comparing them one by one with the historically acquired IF signals of each of multiple azimuth angles, leads to low efficiency in azimuth angle identification. Based on this, the position generation method of some embodiments of this disclosure is as follows: First, acquire the IF signal emitted by the target radar; second, quantize the IF signal to obtain an IF signal vector; wherein, the acquired IF signal emitted by the radar cannot be input into the pre-trained azimuth angle identification model, and the IF signal needs to be quantized to obtain an IF signal vector before it can be input into the pre-trained azimuth angle identification model. Then, input the IF signal vector into the pre-trained azimuth angle identification model to obtain the azimuth angle; here, the acquired IF signal is quantized and then input into the pre-trained azimuth angle identification model to obtain the azimuth angle. This avoids the need to individually compare each intermediate frequency (IF) signal acquired at each historical azimuth angle, thereby improving the efficiency of azimuth angle identification. Next, using the aforementioned azimuth angle, a velocity corresponding to the reflected IF signal and a first duration for the reflected IF signal are generated. This first duration is the time from the time the IF signal is transmitted to the time the reflected IF signal is received. A radio frequency (RF) signal can be transmitted in the direction of the aforementioned azimuth angle to obtain the time point of the transmitted RF signal. In response to determining the location of the transmitted RF signal at a preset device, the transmitted RF signal is reflected. The receiver is controlled to receive the reflected RF signal, so that the receiver converts the received and reflected RF signal into an IF signal, obtaining the time point of receiving the reflected RF signal and the velocity corresponding to the reflected RF signal. The time point of receiving the reflected RF signal is determined as the time point of receiving the reflected IF signal, the velocity corresponding to the reflected RF signal is determined as the velocity corresponding to the reflected IF signal, and the time point of transmitting the RF signal is determined as the time point of transmitting the IF signal. The time interval between the time point of transmitting the intermediate frequency (IF) signal and the time point of receiving the reflected IF signal is determined as the first duration of the radio frequency (RF) signal. Finally, the position of the target radar is generated using the velocity and the first duration. In this embodiment, the acquired IF signal is quantized to obtain an IF signal vector, which is then input into a pre-trained azimuth recognition model. This avoids the need to individually compare the IF signals acquired historically for each of the multiple azimuth angles, thereby improving the efficiency of azimuth recognition.
