Description

Technical Field

[0001] This invention relates to the field of signal processing technology, and specifically to a method for identifying inter-pulse staggered signals based on continuity judgment in the case of leaked pulses. Background Technology

[0002] Staggered pulse signals are a common signal type where the pulse repetition interval (PRI) varies periodically between multiple fixed values ​​according to a preset pattern. A complete frame period consists of multiple different PRI subsequences, and the switching order of each subsequence is fixed, causing the overall PRI variation of the signal to exhibit a long-periodic pattern. This design can effectively improve range ambiguity and optimize detection performance.

[0003] In complex electromagnetic environments, pulse loss (i.e., "missing pulses") often occurs due to environmental noise, multipath effects, signal obstruction, and other factors. This phenomenon results in an incomplete received pulse sequence, abnormal interval values ​​in the PRI sequence, and disrupts the continuity within the staggered subsequences and the integrity of the switching relationships between subsequences.

[0004] Common methods for identifying inter-pulse staggered signals mainly rely on complete or near-complete pulse sequences, which are not robust enough to cases of missing pulses. Under conditions of low signal-to-noise ratio or high pulse loss rate, it is difficult to effectively distinguish between local interval abnormalities caused by missing pulses and genuine random jitter, thus easily misjudging inter-pulse staggered signals in the case of missing pulses as random jitter. Summary of the Invention

[0005] To address the problem of misjudging the staggered type between repeated pulses as random jitter in the case of leaked pulses, the present invention aims to provide a robust adaptive beamforming method based on group sparse reconstruction for radar and communication systems.

[0006] The technical solution to achieve the purpose of this invention is as follows: a method for discriminating inter-pulse staggered signals based on continuity judgment in the case of leaked pulses, comprising the following steps:

[0007] Step 1: Input the pulse repetition interval list of the single radiation source signal after signal sorting and processing into the jitter signal leakage pulse discrimination module, and set the leakage pulse ratio threshold. The jitter signal leakage pulse discrimination module performs recurrence point value feature extraction and recurrence type discrimination on the pulse repetition interval list to obtain a recurrence point value list and recurrence type. If the recurrence type is jitter, and the number of pulse repetition intervals with values ​​greater than the maximum recurrence point value exceeds the leakage pulse ratio threshold of the total number of pulse repetition intervals, proceed to Step 2; otherwise, exit directly.

[0008] Step 2: Input the list of recycle point values ​​into the previous stage recycle point value index matrix calculation module, and set the maximum allowed number of consecutive missed pulses. The previous stage recycle point value index matrix calculation module calculates the previous stage recycle point value index corresponding to each recycle point value when there are no missed pulses between it and the previous stage recycle point value. Based on the relationship between the maximum allowed number of consecutive missed pulses and the total number of recycle point values, it iterates through and calculates the previous stage recycle point value index value corresponding to the missed pulse, forming the previous stage recycle point value index matrix.

[0009] Step 3: Input the list of repeating point values ​​and the maximum allowable number of consecutive missed pulses into the missed pulse repeating matrix calculation module. The missed pulse repeating matrix calculation module calculates the missed pulse repeating corresponding to each repeating point value when there are no missed pulses between it and the previous repeating point value as the current repeating point value. Based on the relationship between the maximum allowable number of consecutive missed pulses and the total number of repeating point values, it iterates through and calculates the missed pulse repeating corresponding to the current repeating point value plus the sum of the first k repeating point values ​​to form the missed pulse repeating matrix.

[0010] Step 4: Input the pulse repetition interval list, the previous stage recycle point value index matrix, and the missed pulse recycle matrix into the inter-pulse staggered continuity matrix calculation module. The inter-pulse staggered continuity matrix calculation module traverses the pulse repetition interval list and the missed pulse recycle matrix, and compares the difference between each pulse repetition interval and the missed pulse recycle value of each recycle point value. If the difference between the m-th pulse repetition interval and the missed pulse recycle value formed when k pulses are missed at the n-th recycle point value is within the recycle tolerance range, then the continuity of the m-th pulse repetition interval at the n-th recycle point value is equal to the continuity of the previous stage recycle point value index corresponding to the (m-1)-th recycle point value when k pulses are missed at the n-th recycle point value plus 1; otherwise, the continuity is 0, forming the inter-pulse staggered continuity matrix.

[0011] Step 5: Input the inter-pulse stagger continuity matrix into the inter-pulse stagger continuity discrimination module. The inter-pulse stagger continuity discrimination module extracts the maximum value of each row of the inter-pulse stagger continuity matrix to form a one-dimensional continuity list, and obtains the continuity amount of each pulse repetition interval. The maximum value in the one-dimensional continuity list is extracted as the maximum continuity amount, and the total continuity amount is calculated cumulatively. If the maximum continuity amount exceeds the maximum continuity amount threshold, and the total continuity amount exceeds the total continuity amount threshold, then the current recycle type is determined to be inter-pulse stagger caused by a missed pulse; otherwise, it is determined to be jitter.

[0012] Compared with the prior art, the significant advantages of this invention are: by establishing a front-stage recycle point value index matrix, a leak pulse recycle matrix, and an inter-pulse staggered continuity matrix, this invention fully utilizes the continuous change law of inter-pulse staggered signals under the leak pulse condition, thereby improving the accuracy of inter-pulse staggered signal type discrimination under the leak pulse condition.

[0013] This invention allows for custom settings of parameters such as the leakage pulse ratio threshold, the maximum allowed number of consecutive leakage pulses, the maximum continuous quantity threshold, and the continuous total quantity threshold, according to actual usage requirements. It is applicable to the identification of inter-pulse staggered signal types under conditions of low signal-to-noise ratio or high pulse loss rate, and has strong robustness and environmental adaptability.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This invention first identifies the case of missing pulses in jitter signals, then calculates the index matrix of the previous stage recycle point, the missing pulse recycle matrix, and the inter-pulse stagger continuity matrix, respectively. Finally, it implements inter-pulse stagger continuity identification, thereby improving the accuracy of inter-pulse stagger signal type identification in the case of missing pulses. The implementation block diagram of the inter-pulse stagger signal identification method based on continuity judgment in the case of missing pulses is shown below. Figure 1 As shown. The specific implementation includes the following steps:

[0024] Step 1: The jitter signal leakage pulse discrimination module inputs the pulse repetition interval list of the single radiation source signal after signal sorting and processing, and sets a leakage pulse ratio threshold. It then performs feature extraction of cycle point values ​​and cycle type discrimination on the pulse repetition interval list, obtaining a cycle point value list and cycle type. If the cycle type is jitter, and the number of values ​​in the pulse repetition interval list greater than the maximum value of the cycle point exceeds the leakage pulse ratio threshold of the total number of pulse repetition intervals, a cycle type discrimination error is suspected to be caused by leakage pulses, and Step 2 is executed; otherwise, the process exits directly.

[0025] Step 2: The preceding stage recycle point value index matrix calculation module inputs the recycle point value list and sets the maximum allowed number of consecutive missed pulses. It calculates the preceding stage recycle point value index when there are no missed pulses between each recycle point value and the preceding stage recycle point value. Based on the relationship between the maximum allowed number of consecutive missed pulses and the total number of recycle points, it iterates and calculates the preceding stage recycle point value index value corresponding to the missed pulse. The preceding stage recycle point value index matrix is ​​formed based on the calculation results.

[0026] Step 3: The leaky pulse repeatability matrix calculation module takes the list of repeatability point values ​​and the maximum allowed number of consecutive leaky pulses as input. It calculates the leaky pulse repeatability corresponding to each repeatability point value when there are no leaky pulses between it and the previous repeatability point value, which is the current repeatability point value. Based on the relationship between the maximum allowed number of consecutive leaky pulses and the total number of repeatability point values, it iterates through the modules to calculate the leaky pulse repeatability corresponding to the leaky pulse, which is the current repeatability point value plus the sum of the previous k repeatability point values. The leaky pulse repeatability matrix is ​​then formed based on the calculation results.

[0027] Step 4: Input the pulse repetition interval list, the previous cycle point index matrix, and the missed pulse cycle matrix into the pulse repetition interval calculation module. Iterate through the pulse repetition interval list and the missed pulse cycle matrix, comparing the difference between each pulse repetition interval and the missed pulse cycle value of each cycle point. If the difference between the m-th pulse repetition interval and the missed pulse cycle value formed when k pulses are missed at the n-th cycle point is within the cycle tolerance range, then the continuity value of the m-th pulse repetition interval at the n-th cycle point is equal to the continuity value corresponding to the previous cycle point index when k pulses are missed at the n-th cycle point, plus 1; otherwise, the continuity value is 0.

[0028] Step 5: The inter-pulse staggered continuity discrimination module inputs the inter-pulse staggered continuity matrix. It extracts the maximum value from each row of the inter-pulse staggered continuity matrix to form a one-dimensional continuity list, obtaining the continuous quantity for each pulse repetition interval. The maximum value in the one-dimensional continuity list is extracted as the maximum continuous quantity, and the total continuous quantity is calculated cumulatively. If the maximum continuous quantity exceeds the maximum continuous quantity threshold, and the total continuous quantity exceeds the total continuous quantity threshold, the current recycle type is determined to be inter-pulse staggered caused by a missed pulse; otherwise, it is determined to be jitter.
