Abstract


Along with the rapid development of information technology and its wide application in the military area, modern communication system, especially the radar system plays more and more important role in modern warfare. Electronic countermeasures (ECM) and electromagnetic counter-countermeasures (ECCM) has become the eternal subject of modern information war. Since the battlefield is becoming more severe situation, this paper taked the warning radar and PD radar as background, researched the anti-jamming performance of the phased array radar, analyzed the ECCM assessment criteria, then according to the characteristics of the antenna array orientation image, analyzed digital beamforming method, and proposed a method of ECCM based on antenna beam optimization.The main content is:First of all, the pulse pressure phased array radar, broadband radar, the background and application of ECM and ECCM technology were introduced;Secondly, Radar ECCM technology was introduced, and several ECCM evaluation methods are analyzed. The combination ECCM method was discussed. This paper unifies ECCM antenna array method and pulse compression method to improve the performance of radar ECCM system.Thirdly, the pulse compression technology is analyzed. Mainly aimed at the commonly used for pulse pressure phased array radar system structure, chirp signal (LFM) features and estimation methods were introduced. And a kind of time-FM slope distribution LFM signal cross suppression method is proposed.Fourthly, in the condition that interference sources are known, the performance of digital adaptive interference nulling is analyzed. In the condition that interference sources are unknown, ECCM method is proposed based on radiation pattern, through simulation test, the result indicated that the method can effectively reduce the sidelobe and inhibit clutter to achieve the purpose of reduce interference signal.Lastly, the full paper is concluded, the result of this paper was gived and analyzed, and the future of this field which can be impoved and the further research directions are pointed out.The result of this paper has certain significance in the technology of radar anti-interference.
