Description

Technical Field

[0001] Embodiments of the present disclosure relate to the field of computer technology, and in particular to a method, device, equipment, and medium for generating a radar signal pulse repetition interval. Background Art

[0002] The pulse repetition interval is the time interval between two consecutive pulses emitted by the radar. Generally speaking, the pulses of the radar are repeated, but the pulse interval is not necessarily repeated. Even if the interval itself is not repeated, it is generally still called the pulse repetition interval. At present, when determining the pulse repetition interval, the usual method is to determine whether each signal point in the received radar signal is the arrival time of the pulse to determine the pulse repetition interval.

[0003] However, the inventors have found that when the pulse repetition interval is determined in the above manner, the following technical problems often occur:

[0004] First, in a complex electromagnetic environment, the signal-to-noise ratio of the radar signal is low, resulting in low pulse repetition interval accuracy.

[0005] Second, the signal interval division method is not considered, and judgment needs to be made for each signal point, resulting in a long time spent in determining the pulse arrival time.

[0006] The above information disclosed in this Background section is only for enhancement of understanding of the background of the inventive concept and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art. Summary of the invention

[0007] The content of this disclosure is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this disclosure is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0008] Some embodiments of the present disclosure propose methods, devices, electronic devices, and computer-readable media for generating a radar signal pulse repetition interval to solve one or more of the technical problems mentioned in the above background technology section.

[0009] In a first aspect, some embodiments of the present disclosure provide a method for generating a radar signal pulse repetition interval, the method comprising: acquiring a target intermediate frequency signal; inputting the target intermediate frequency signal into a pre-trained pulse start and end point positioning model to obtain an interval point mean sequence corresponding to the target intermediate frequency signal; based on the interval point mean sequence, generating a starting point and an end point of each pulse of the target intermediate frequency signal; for the starting points of any two pulses in the target intermediate frequency signal, generating a pulse interval corresponding to the starting points of the any two pulses; and generating a radar signal pulse repetition interval set corresponding to the target intermediate frequency signal based on the generated pulse intervals.

[0010] In a second aspect, some embodiments of the present disclosure provide a radar signal pulse repetition interval generating device, the device comprising: an acquisition unit, configured to acquire a target intermediate frequency signal; an input unit, configured to input the target intermediate frequency signal into a pre-trained pulse start and end point positioning model to obtain an interval point mean sequence corresponding to the target intermediate frequency signal; a first generation unit, configured to generate a starting point and an end point of each pulse of the target intermediate frequency signal based on the interval point mean sequence; a second generation unit, configured to generate a pulse interval corresponding to the starting points of any two pulses in the target intermediate frequency signal; and a third generation unit, configured to generate a radar signal pulse repetition interval set corresponding to the target intermediate frequency signal based on the generated pulse intervals.

[0011] In a third aspect, some embodiments of the present disclosure provide an electronic device comprising: one or more processors; a storage device on which one or more programs are stored, and 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 manner of the above-mentioned first aspect.

[0012] In a fourth aspect, some embodiments of the present disclosure provide a computer-readable medium having a computer program stored thereon, wherein when the program is executed by a processor, the method described in any implementation manner of the above-mentioned first aspect is implemented.

[0013] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the radar signal pulse repetition interval generation method of some embodiments of the present disclosure, the influence of the low signal-to-noise ratio of the radar signal is reduced, and the accuracy of the pulse repetition interval is improved. Specifically, the reason for the low accuracy of the pulse repetition interval is that in a complex electromagnetic environment, the signal-to-noise ratio of the radar signal is low, resulting in low accuracy of the pulse repetition interval. Based on this, the radar signal pulse repetition interval generation method of some embodiments of the present disclosure, first, obtain the target intermediate frequency signal. Here, the target intermediate frequency signal is a signal that can provide data support for the generation of the pulse repetition interval. Secondly, the above-mentioned target intermediate frequency signal is input into the pre-trained pulse start and end point positioning model to obtain the interval point mean sequence corresponding to the above-mentioned target intermediate frequency signal. Therefore, the interval point mean sequence corresponding to the above-mentioned target intermediate frequency signal can be generated by the pulse start and end point positioning model, which reduces the influence of the low signal-to-noise ratio of the radar signal, thereby providing preparation for the confirmation of the starting point and end point of each pulse of the above-mentioned target intermediate frequency signal. Then, based on the above-mentioned interval point mean sequence, the starting point and end point of each pulse of the above-mentioned target intermediate frequency signal are generated. Thus, through the above-mentioned interval point mean sequence, the starting point and the end point of each pulse of the target intermediate frequency signal with a relatively accurate fit can be obtained. Finally, for the starting points of any two pulses in the above-mentioned target intermediate frequency signal, the pulse interval corresponding to the starting points of the above-mentioned any two pulses is generated. According to each generated pulse interval, a set of radar signal pulse repetition intervals corresponding to the above-mentioned target intermediate frequency signal is generated. Thus, through the starting points of any two pulses in the target intermediate frequency signal, the pulse interval corresponding to the starting points of any two pulses is obtained. According to each generated pulse interval, the pulse repetition intervals of each radar signal corresponding to the above-mentioned target intermediate frequency signal with a higher accuracy are obtained. Also because the starting point and the end point of each pulse of the target intermediate frequency signal with a relatively accurate fit are obtained through the pulse start and end point positioning model of the radar signal with a low signal-to-noise ratio, the radar signal pulse repetition interval corresponding to the starting points of any two pulses with a higher accuracy is obtained through the starting points of any two pulses in the above-mentioned target intermediate frequency signal. Thus, the influence of the low signal-to-noise ratio of the radar signal is reduced, and the accuracy of the pulse repetition interval is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0024] Figure 1 The flowchart 100 of some embodiments of the radar signal pulse repetition interval generation method according to the present disclosure is shown. The radar signal pulse repetition interval generation method comprises the following steps:

[0025] Step 101, obtaining a target intermediate frequency signal.

[0026] In some embodiments, the execution subject (e.g., a computing device) of the radar signal pulse repetition interval generation method can obtain the target intermediate frequency signal based on the associated electronic reconnaissance equipment. Among them, the electronic reconnaissance equipment can be a device that searches and intercepts the radio signals emitted by the enemy equipment. The above-mentioned enemy equipment may include but is not limited to at least one of the following: radar, radio communication equipment, navigation equipment, remote control equipment, weapon guidance system, electronic jamming system and optoelectronic equipment. Here, the target intermediate frequency signal can be the intermediate frequency signal emitted by each radar corresponding to the pulse repetition interval to be generated. In practice, based on the associated electronic reconnaissance equipment, the above-mentioned execution subject can use the electronic reconnaissance equipment to intercept the electromagnetic signals emitted by each radar corresponding to the pulse repetition interval to be generated. It should be pointed out that the above-mentioned electronic reconnaissance equipment may include but is not limited to: electronic reconnaissance aircraft, electronic reconnaissance ships, ground electronic listening stations and electronic reconnaissance satellites. The above-mentioned electromagnetic signal may be an intermediate frequency signal.

[0027] Step 102: input the target intermediate frequency signal into a pre-trained pulse start and end point positioning model to obtain a sequence of interval point mean values ​​corresponding to the target intermediate frequency signal.

[0028] In some embodiments, the above-mentioned execution subject can input the above-mentioned target intermediate frequency signal into a pre-trained pulse start and end point positioning model to obtain the interval point mean sequence corresponding to the above-mentioned target intermediate frequency signal. Here, the pulse start and end point positioning model can refer to a neural network model that takes the target intermediate frequency signal as input and the interval point mean sequence corresponding to the target intermediate frequency signal as output. For example, the above-mentioned neural network model can be a ResNet network (Residual Network). Here, the interval point mean sequence corresponding to the target intermediate frequency signal can be a sequence of the mean values ​​of each normalized signal point value in each signal interval of the target intermediate frequency signal. The normalized signal point value can be the value of the signal point in [0, 1]. The value of the noise signal point tends to 0. The value of the pulse point tends to 1. The above-mentioned signal intervals can be the ordered signal intervals into which the signal points corresponding to the target intermediate frequency signal are divided in units of preset interval points.

[0029] In some optional implementations of some embodiments, the pulse start and end point positioning model can be trained in the following way:

[0030] The first step is to obtain a sample set. The samples in the sample set include sample signals and sample interval point means corresponding to the sample signals. It should be noted that the execution subject of training the pulse start and end point positioning model can be the above execution subject or other computing devices.

[0031] In the second step, the following training steps are performed based on the sample set:

[0032] In the first training step, the sample signals of at least one sample in the sample set are respectively input into the initial pulse start and end point positioning model to obtain the interval point mean corresponding to each sample in the at least one sample. The initial pulse start and end point positioning model is an initial neural network that can obtain the sample interval point mean according to the sample signal. The initial neural network can be a neural network to be trained.

[0033] The second training step is to compare the interval point mean corresponding to each sample in the at least one sample with the corresponding sample interval point mean. Here, the comparison can be a comparison of the size of the interval point mean corresponding to each sample in the at least one sample with the corresponding sample interval point mean.

[0034] The third training step is to determine whether the initial pulse start and end point positioning model reaches a preset optimization target based on the comparison result. The above-mentioned optimization target may refer to that the error value of the loss function of the above-mentioned initial pulse start and end point positioning model to be trained is less than or equal to a preset error threshold. Here, the loss function may be a mean square error (MSE) loss function. The preset error threshold may be 0.0001.

[0035] In the fourth training step, in response to determining that the initial pulse start and end point positioning model has achieved the above-mentioned optimization goal, the initial pulse start and end point positioning model is determined as the trained pulse start and end point positioning model.

[0036] Optionally, the step of training the pulse start and end point positioning model further includes:

[0037] In the third step, in response to determining that the initial pulse start and end point positioning model does not achieve the above optimization goal, the network parameters of the initial pulse start and end point positioning model are adjusted, and the sample set is composed of unused samples, and the adjusted initial pulse start and end point positioning model is used as the initial pulse start and end point positioning model, and the above training step is performed again. As an example, the network parameters of the above initial pulse start and end point positioning model can be adjusted by using a back propagation algorithm (BP algorithm) and a gradient descent method (such as a small batch gradient descent algorithm).

[0038] Step 103: Generate the starting point and the ending point of each pulse of the target intermediate frequency signal based on the interval point mean sequence.

[0039] In some embodiments, the execution entity may generate a starting point and an ending point of each pulse of the target intermediate frequency signal based on the interval point mean sequence.

[0040] In practice, based on the above interval point mean value sequence, the above execution subject can generate the starting point and the ending point of each pulse of the above target intermediate frequency signal through the following steps:

[0041] In the first step, the product of each interval point mean in the above interval point mean sequence and the preset interval point number is determined as the interval pulse point number to obtain the interval pulse point number sequence.

[0042] In the second step, for each interval pulse point number in the interval pulse point number sequence, in response to determining that the interval pulse point number is greater than zero and less than the preset interval point number, the following steps are performed:

[0043] The first sub-step is, in response to determining that the interval pulse point number in the above-mentioned interval pulse point number sequence that is arranged before the above-mentioned interval pulse point number and adjacent to the above-mentioned interval pulse point number is equal to zero, selecting a signal point that meets the preset pulse starting condition from each signal point in the signal interval corresponding to the above-mentioned interval pulse point number, and using the selected signal point as the starting point of the pulse corresponding to the above-mentioned signal interval. Among them, the above-mentioned preset pulse starting condition is that the sequence number of the signal point in the above-mentioned various signal points is a first numerical value. Among them, the above-mentioned first numerical value is the sum of the target difference and 1. The above-mentioned target difference is the difference between the above-mentioned preset interval point number and the above-mentioned interval pulse point number. As an example, the above-mentioned interval pulse point number may be 32. The signal point in the signal interval corresponding to the above-mentioned interval pulse point number may be 64. The 33rd signal point in the signal interval corresponding to the above-mentioned interval pulse point number is the starting point of the pulse corresponding to the above-mentioned signal interval.

[0044] The second sub-step, in response to determining that the interval pulse point number arranged before the interval pulse point number and adjacent to the interval pulse point number in the interval pulse point number sequence is equal to zero, and the first interval pulse point number is greater than zero, the signal point corresponding to the first interval pulse point number among the various signal points in the first signal interval is determined as the termination point of the pulse corresponding to the above signal interval. Among them, the first interval pulse point number is the interval pulse point number arranged after the interval pulse point number in the interval pulse point number sequence and meets the preset pulse termination interval condition. The preset pulse termination interval condition is that the interval pulse points after the interval pulse point number and before the first interval pulse point number are all the preset interval points, and the first interval pulse point number after the first interval pulse point number is zero. The above first signal interval is the signal interval corresponding to the first interval pulse point number. Specifically, the first interval pulse point number may be 32. The signal point in the signal interval corresponding to the first signal interval pulse point number may be 64. The signal point corresponding to the first interval pulse point number 32 among the various signal points in the first signal interval is the termination point of the pulse corresponding to the above signal interval.

[0045] The third sub-step, in response to determining that the interval pulse point number in the above interval pulse point number sequence that is arranged after the above interval pulse point number and adjacent to the above interval pulse point number is equal to zero, select a signal point that meets the preset pulse termination condition from each signal point in the signal interval corresponding to the above interval pulse point number, and use the selected signal point as the termination point of the pulse corresponding to the above signal interval. The above preset pulse termination condition is that the sequence number of the signal point in the above signal points is a second numerical value. The above second numerical value is the above interval pulse point number. Specifically, the above interval pulse point number may be 32. The signal point in the signal interval corresponding to the above interval pulse point number may be 64. The 32nd signal point in the signal interval corresponding to the above interval pulse point number is the termination point of the pulse corresponding to the above signal interval.

[0046] The fourth sub-step, in response to determining that the interval pulse point number arranged after the interval pulse point number and adjacent to the interval pulse point number in the interval pulse point number sequence is equal to zero, and the second interval pulse point number is greater than zero, the signal point corresponding to the second interval pulse point number among the signal points in the second signal interval is determined as the starting point of the pulse corresponding to the signal interval. Among them, the second interval pulse point number is the interval pulse point number arranged before the interval pulse point number in the interval pulse point number sequence and meets the preset pulse starting interval condition. The preset pulse starting interval condition is that the interval pulse points before the interval pulse point number to the second interval pulse point number are all the preset interval points, and the first interval pulse point number before the second interval pulse point number is zero. The second signal interval is the signal interval corresponding to the second interval pulse point number. Specifically, the second interval pulse point number may be 32. The signal point in the signal interval corresponding to the second signal interval pulse point number may be 64. The signal point corresponding to the second interval pulse point number 32 among the signal points in the second signal interval is the starting point of the pulse corresponding to the signal interval.

[0047] In the third step, for each interval pulse point number in the interval pulse point number sequence, in response to determining that the interval pulse point number is equal to the preset interval point number, the following steps are performed:

[0048] The first sub-step is, in response to determining that the interval pulse point number in the interval pulse point number sequence arranged before the interval pulse point number and adjacent to the interval pulse point number is equal to zero, determining the first signal point in the signal interval corresponding to the interval pulse point number as the starting point of the pulse corresponding to the signal interval. Specifically, the interval pulse point number may be 64. The signal point in the signal interval corresponding to the interval pulse point number may be 64. The first signal point in the signal interval corresponding to the interval pulse point number is the starting point of the pulse corresponding to the signal interval.

[0049] The second sub-step, in response to determining that the interval pulse point number in the interval pulse point number sequence that is arranged after the interval pulse point number and adjacent to the interval pulse point number is equal to zero, determines the last signal point in the signal interval corresponding to the interval pulse point number as the end point of the pulse corresponding to the signal interval. Specifically, the interval pulse point number may be 64. The signal point in the signal interval corresponding to the interval pulse point number may be 64. The 64th signal point in the signal interval corresponding to the interval pulse point number is the end point of the pulse corresponding to the signal interval.

[0050] The relevant content of the above step 103, as an inventive point of an embodiment of the present disclosure, solves the second technical problem mentioned in the background technology, "the signal interval division method is not considered, and a judgment needs to be made for each signal point, resulting in a long time to determine the pulse arrival time". The factors that take a long time to determine the pulse arrival time are often as follows: the signal interval division method is not considered, and a judgment needs to be made for each signal point, resulting in a long time to determine the pulse arrival time. If the above factors are solved, a relatively accurate effect of position fitting of the pulse starting point and the end point can be achieved. In order to achieve this effect, first, the product of the mean of each interval point in the above interval point mean sequence and the preset interval point number is determined as the interval pulse point number, and an interval pulse point number sequence is obtained. Therefore, by multiplying the mean of each interval point in the above interval point mean sequence with the preset interval point number, the interval pulse point number before the signal point corresponding to the target intermediate frequency signal is divided into intervals according to the preset number of points is obtained, thereby obtaining an interval pulse point number sequence. Secondly, for each interval pulse point number in the above interval pulse point number sequence, in response to determining that the above interval pulse point number is greater than zero and less than the above preset interval point number, the following steps are performed: in response to determining that the interval pulse point number in the above interval pulse point number sequence that is arranged before the above interval pulse point number and adjacent to the above interval pulse point number is equal to zero, a signal point that meets the preset pulse start condition is selected from each signal point in the signal interval corresponding to the above interval pulse point number, and the selected signal point is used as the starting point of the pulse corresponding to the above signal interval. In response to determining that the interval pulse point number in the above interval pulse point number sequence that is arranged before the above interval pulse point number and adjacent to the above interval pulse point number is equal to zero, and the first interval pulse point number is greater than zero, the signal point corresponding to the first interval pulse point number among each signal point in the first signal interval is determined as the end point of the pulse corresponding to the above signal interval. Wherein, the first interval pulse point number is the interval pulse point number in the above interval pulse point number sequence that is arranged after the above interval pulse point number and meets the preset pulse end interval condition. The preset pulse termination interval condition is that the pulse points of each interval after the interval pulse point number and before the first interval pulse point number are all the preset interval points, and the first interval pulse point number after the first interval pulse point number is zero. The first signal interval is the signal interval corresponding to the first interval pulse point number. In response to determining that the interval pulse point number arranged after the interval pulse point number and adjacent to the interval pulse point number in the interval pulse point number sequence is equal to zero, a signal point that meets the preset pulse termination condition is selected from each signal point in the signal interval corresponding to the interval pulse point number, and the selected signal point is used as the termination point of the pulse corresponding to the signal interval.In response to determining that the interval pulse point number arranged after the interval pulse point number and adjacent to the interval pulse point number in the interval pulse point number sequence is equal to zero, and the second interval pulse point number is greater than zero, the signal point corresponding to the second interval pulse point number among the signal points in the second signal interval is determined as the starting point of the pulse corresponding to the signal interval. Among them, the second interval pulse point number is the interval pulse point number arranged before the interval pulse point number in the interval pulse point number sequence and meets the preset pulse starting interval condition. The preset pulse starting interval condition is that the interval pulse points before the interval pulse point number to the second interval pulse point number are all the preset interval points, and the first interval pulse point number before the second interval pulse point number is zero. The second signal interval is the signal interval corresponding to the second interval pulse point number. Thus, the starting point and the ending point of the pulse are determined when the interval pulse point number is greater than zero and less than the preset interval point number. Thereby, the accuracy of the position of the fitting pulse starting point and the ending point is improved. Finally, for each interval pulse point number in the above interval pulse point number sequence, in response to determining that the above interval pulse point number is equal to the above preset interval point number, the following steps are performed: in response to determining that the interval pulse point number in the above interval pulse point number sequence that is arranged before the above interval pulse point number and adjacent to the above interval pulse point number is equal to zero, the first signal point in the signal interval corresponding to the above interval pulse point number is determined as the starting point of the pulse corresponding to the above signal interval. In response to determining that the interval pulse point number in the above interval pulse point number sequence that is arranged after the above interval pulse point number and adjacent to the above interval pulse point number is equal to zero, the last signal point in the signal interval corresponding to the above interval pulse point number is determined as the ending point of the pulse corresponding to the above signal interval. Thus, the starting point and ending point of the pulse are determined when the above interval pulse point number is equal to the above preset interval point number. The accuracy of the position of the fitting pulse starting point and ending point is improved.

[0051] Step 104: for the starting points of any two pulses in the target intermediate frequency signal, generate a pulse interval corresponding to the starting points of any two pulses.

[0052] In some embodiments, the execution entity may generate a pulse interval corresponding to the starting points of any two pulses in the target intermediate frequency signal.

[0053] In practice, for the starting points of any two pulses in the target intermediate frequency signal, the execution subject may generate the pulse interval corresponding to the starting points of any two pulses through the following steps:

[0054] In the first step, the number of interval points between the starting points of any two pulses is multiplied by the preset time interval to obtain the interval duration. The number of interval points may be the number of signal points between the starting points of any two pulses. The preset time interval may be the time interval between two adjacent signal points in the target intermediate frequency signal. For example, the preset time interval may be 0.2ns.

[0055] The second step is to determine the duration of the above interval as the pulse interval corresponding to the starting points of any two pulses.

[0056] Step 105: Generate a radar signal pulse repetition interval set corresponding to the target intermediate frequency signal according to the generated pulse intervals.

[0057] In some embodiments, the execution subject may generate a radar signal pulse repetition interval set corresponding to the target intermediate frequency signal using a pulse repetition interval estimation algorithm based on the generated pulse intervals, wherein the pulse repetition interval estimation algorithm may be a Sequential Difference Histogram (SDIF) algorithm.

[0058] Optionally, according to the radar signal pulse repetition interval set, a radar signal pulse repetition interval pattern corresponding to each radar signal pulse repetition interval in the radar signal pulse repetition interval set is generated to obtain a radar signal pulse repetition interval pattern set.

[0059] In some embodiments, the execution subject may generate a radar signal pulse repetition interval pattern corresponding to each radar signal pulse repetition interval in the radar signal pulse repetition interval set according to the radar signal pulse repetition interval set, and obtain a radar signal pulse repetition interval pattern set. The radar signal pulse repetition interval pattern may include but is not limited to at least one of the following: a fixed pulse repetition interval pattern, a jittered pulse repetition interval pattern, a staggered pulse repetition interval pattern, and a sliding pulse repetition interval pattern.

[0060] In practice, the execution subject may generate a radar signal pulse repetition interval pattern corresponding to each radar signal pulse repetition interval in the radar signal pulse repetition interval set through a classification algorithm. The classification algorithm may be a decision tree classification algorithm. For example, the decision tree classification algorithm may be a C4.5 algorithm. Specifically, the execution subject may input the radar signal pulse repetition interval into a pre-trained radar signal pulse repetition interval pattern classification decision tree to obtain a radar signal pulse repetition interval pattern corresponding to each radar signal pulse repetition interval in the radar signal pulse repetition interval set. Among them, the training data in the training data set used to train the radar signal pulse repetition interval pattern classification decision tree may include radar signal pulse repetition intervals and radar signal pulse repetition interval pattern labels corresponding to the radar signal pulse repetition intervals. Here, the radar signal pulse repetition interval pattern label may include but is not limited to at least one of the following: a fixed pulse repetition interval pattern, a jittered pulse repetition interval pattern, a staggered pulse repetition interval pattern, and a slip pulse repetition interval pattern. Among them, the fixed pulse repetition interval pattern may represent that the adjacent radar signal pulse repetition intervals are the same. The jittered pulse repetition interval pattern may represent that the adjacent radar signal pulse repetition intervals are within a preset pulse repetition interval parameter limit interval range. The staggered pulse repetition interval pattern may indicate that the pulse repetition intervals of adjacent radar signals change once after a preset number of pulse cycles. The slipping pulse repetition interval pattern may indicate that the pulse repetition intervals of adjacent radar signals change monotonically over time.

[0061] Optionally, radar signal sorting is performed on the target intermediate frequency signal according to the radar signal pulse repetition interval pattern set to obtain a radar signal sorting result.

[0062] In some embodiments, the execution entity may perform radar signal sorting on the target intermediate frequency signal according to the radar signal pulse repetition interval pattern set.

[0063] In practice, the execution entity may perform radar signal sorting on the target intermediate frequency signal through the following steps:

[0064] In the first step, for each radar signal pulse repetition interval pattern in the radar signal pulse repetition interval pattern set, each pulse corresponding to the radar signal pulse repetition interval pattern is selected from the pulse sequence included in the target intermediate frequency signal as a sorting pulse to form a sorting pulse sequence. The corresponding relationship between the radar signal pulse repetition interval pattern and the pulses can be: the pattern of the radar signal pulse repetition interval between any two adjacent pulses in the pulses is the same as the radar signal pulse repetition interval pattern.

[0065] In the second step, the composed sorting pulse sequences are determined as radar signal sorting results.

[0066] Optionally, according to the radar signal sorting result, at least one radar signal corresponding to the radar signal sorting result is subjected to deceptive interference. Specifically, first, the execution subject may determine each sorting pulse sequence included in the radar signal sorting result as a radar signal to obtain a radar signal set. Then, the execution subject may deform at least one radar signal in the radar signal set. Then, each radar signal after deformation may be forwarded to the radar corresponding to the radar signal. Thus, the radar corresponding to the radar signal after deformation may be tracked to a fake non-existent target, thereby protecting the real target. The execution subject may also generate a noise signal set, and send out the generated noise signal set. Thus, the enemy radar may be interfered with by the sent noise signal set. Each noise signal in the noise signal set may be used as a false target, making it difficult for the enemy radar system to obtain valuable information therefrom, and even causing the data processing system of the radar to enter a crash state due to too many false targets.

[0067] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the radar signal pulse repetition interval generation method of some embodiments of the present disclosure, the influence of the low signal-to-noise ratio of the radar signal is reduced, and the accuracy of the pulse repetition interval is improved. Specifically, the reason for the low accuracy of the pulse repetition interval is that in a complex electromagnetic environment, the signal-to-noise ratio of the radar signal is low, resulting in low accuracy of the pulse repetition interval. Based on this, the radar signal pulse repetition interval generation method of some embodiments of the present disclosure, first, obtain the target intermediate frequency signal. Here, the target intermediate frequency signal is a signal that can provide data support for the generation of the pulse repetition interval. Secondly, the above-mentioned target intermediate frequency signal is input into the pre-trained pulse start and end point positioning model to obtain the interval point mean sequence corresponding to the above-mentioned target intermediate frequency signal. Therefore, the interval point mean sequence corresponding to the above-mentioned target intermediate frequency signal can be generated by the pulse start and end point positioning model, which reduces the influence of the low signal-to-noise ratio of the radar signal, thereby providing preparation for the confirmation of the starting point and end point of each pulse of the above-mentioned target intermediate frequency signal. Then, based on the above-mentioned interval point mean sequence, the starting point and end point of each pulse of the above-mentioned target intermediate frequency signal are generated. Thus, through the above-mentioned interval point mean sequence, the starting point and the end point of each pulse of the target intermediate frequency signal with a relatively accurate fit can be obtained. Finally, for the starting points of any two pulses in the above-mentioned target intermediate frequency signal, the pulse interval corresponding to the starting points of the above-mentioned any two pulses is generated. According to each generated pulse interval, a set of radar signal pulse repetition intervals corresponding to the above-mentioned target intermediate frequency signal is generated. Thus, through the starting points of any two pulses in the target intermediate frequency signal, the pulse interval corresponding to the starting points of any two pulses is obtained. According to each generated pulse interval, the pulse repetition intervals of each radar signal corresponding to the above-mentioned target intermediate frequency signal with a higher accuracy are obtained. Also because the starting point and the end point of each pulse of the target intermediate frequency signal with a relatively accurate fit are obtained through the pulse start and end point positioning model of the radar signal with a low signal-to-noise ratio, the radar signal pulse repetition interval corresponding to the starting points of any two pulses with a higher accuracy is obtained through the starting points of any two pulses in the above-mentioned target intermediate frequency signal. Thus, the influence of the low signal-to-noise ratio of the radar signal is reduced, and the accuracy of the pulse repetition interval is improved.
