一种针对LFM-MIMO雷达的新型间歇采样转发干扰方法
A Novel Intermittent Sampling Repeater Jamming Method for LFM-MIMO Radar
摘要
Abstract
In response to the jamming issue of linear frequency modulation-multiple input multiple out-put(LFM-MIMO)radar,a periodic alternating non-uniform intermittent sampling repeater jamming(ISRJ)method is proposed.In this method,the sampling duration is periodically changed.The pulse signal of the LFM-MIMO radar is subjected to short-time sampling,followed by multiple forwarding,and this process is repeated until the end of the pulse.First,the basic principles of ISRJ in uniform and non-uniform modes are elaborated.Then,the non-uniform ISRJ signal model for the LFM-MIMO radar signals is derived,and the causes of false targets generated by this model are analyzed.Through simulation experiments,the impacts of parameters such as sampling pulse width,sampling method,and forwarding times on the jamming effect are analyzed.The results indicate that a group of false tar-gets with non-regular distribution can be generated by using the proposed method,and a certain degree of suppression jamming effect can be achieved on the basis of deception jamming when a higher num-ber of forwarding times is adopted.关键词
