对有源无源双基地雷达的诱骗干扰效能分析

Effciency Analysis of Decoy Jamming Against Active and Passive Bistatic Radar

针对T/R-R型有源无源双基地雷达收发分置、复合探测难以有效干扰的问题,建立了有源无源双基地雷达威力模型,分析了其探测流程,提出了无源区诱骗、有源区干扰的诱骗式干扰方法,从而提高了对双基地雷达干扰效能。文中构建了干扰功率谱密度比和距离积压缩因子两个干扰效能评价指标,在此基础上对诱骗式干扰与非诱骗式干扰效能进行了理论分析和仿真实验。仿真结果表明:诱骗式干扰是对有源无源双基地雷达的一种有效干扰方法,干扰效能优于非诱骗式干扰。

T/R-R bistatic radar can＇t be jammed in efficiency way, because of separation of the transmitter and receiver and com- pound detection of active and passive. Decoy jamming is put forward to against the bistatic radar for improving the jamming effi- ciency by decoy in passive detect zone and jam in active zone based on detection model and the detection process of active and pas- sive bistatic radar are analyzed. The efficiency evaluation indicators are based on the jamming power spectral density and distance product compression factor. The efficiency of decoy jamming and non-decoy jamming are analyzed and simulated theoretically. The results show that the decoy jamming efficiency is higher than non-decoy jamming, which is an effective way to against active and passive bistatic radar.
