Research On Jamming Technology Of Anti-ship Radar Seeker

With the development of science and technology,the development of land and air combat technology,the importance of sea combat is gradually reflected.In the current sea war,antiship missile is the biggest threat to the target of sea ship.How to protect the friendly ship from the attack of the enemy’s anti-ship missile is the research focus in the corresponding field at home and abroad.This paper mainly studies the jamming effect of shipboard active jamming and outboard active jamming on anti-ship missile 1.This paper analyzes the structure of the radar system of the anti-ship missile seeker,analyzes the radar antenna,the generation of the transmitting signal,the simulation of the echo signal,the receiver,especially the pulse compression,the detection of the moving target,the display of the moving target,the detection of the CFAR in the signal processor,and the track initiation,the track filtering,the track correlation and the end of the track in the data processor,and establishes the corresponding The simulation model is analyzed.2.The signal model of Shipborne active jamming is established,which includes noise AM signal,noise FM signal,noise phase modulation signal,range pull jamming signal,smart noise jamming signal,multiple false targets jamming signal and dense false targets jamming signal.The corresponding jamming signal is combined with radar system,and each kind of jamming is analyzed by simulation Interference effect of interference.3.The signal model of outboard active jamming is established,including outboard active jamming and outboard suppression jamming.The mechanism of outboard active jamming is analyzed and the corresponding jamming model is established.The jamming effect of outboard active jamming is analyzed with radar system.For outboard suppression jamming,the outboard jamming is analyzed by changing the position relationship between jammer and target ship The influence of suppression jamming on the burn through distance of radar.
