Research On Key Technology Of Quickly Recognizing Electronic Target Of Key Radar

In the future war,the real-time and accuracy requirements of the enemy’s key radar electronic target recognition are getting higher and higher.In this paper,for the current radar reconciliation system,there are processing processes rigid,adaptable weakly to complex electromagnetic environment,and not strongly targeted and so on。It is proposed to use the a priori information of radar electronic target to quickly extract the radar sequence of interest radar,bypass the signal sorting process and realize the rapid identification of key radar electronic target.The main work is as follows:Fast Target Recognition of Key Radar Target Based on PRI Sequence Matching Algorithm.First,a typical PRI sequence for rapid identification is proposed;and then put forward the application of two different algorithms,namely PRI sequence matching algorithm and extended period PRI sequence matching algorithm;Final,using PRI sequence to realize the rapid identification of key radar Electronic targets.The algorithm is highly targeted and can achieve fast processing of multiple targets at the same time.Fast Radar Target Recognition Based on Radar Crystal Characteristics.From the principle of generating the radar signal,it is concluded that the generation of PRI parameters is related to the crystal characteristics of the radar.Therefore,an algorithm for fast target recognition based on radar crystal characteristics is proposed.The algorithm can quickly identify the pulse sequence of the key radar signal,and the recognition effect of PRI complex radar signal is better.It is also proposed to use the radio frequency parameters to further identify the working state of the key radar.Radar Target Recognition Based on Small Sample Pulse Sequence Matching.The typical small sample pulse sequence is extracted according to the a priori information of the key radar target,and the typical small sample pulse sequence and the pulse stream are used to do similar cross correlation matching.The algorithm not only simplifies the identification process of radar radiation source,but also improves the processing speed effectively.Fast Recognition of Key Radar Based on Dynamic Batch Processing.In order to further improve the rapid identification of the key radar signal in a very long pulse flow.Firstly,the parallel processing of block multi-process is proposed,and the identification of the key radar electronic target is realized by using the typical small sample pulse sequence matching.Finally,the recognition result is merged by dynamic batch processing.
