| 摘 要： | 针对传统转发干扰对ISAR只能形成点斑干扰的不足,提出了ISAR散射波干扰方法,该方法将截获的ISAR发射信号直接转发至目标,经目标散射后形成散射波干扰信号,获得了更为丰富的干扰信息。文中根据双基地ISAR的成像理论,将干扰机与ISAR接收机分别等效为双基地ISAR的发射站和接收站,建立了ISAR散射波干扰模型,分析了散射波干扰的功率以及对ISAR的干扰效果。研究结果表明通过控制干扰机的转发时延和等效双基地角,散射波干扰可以对ISAR形成单个或多个不同位置的假目标欺骗干扰,而且实现简便,是一种对ISAR形成假目标数量欺骗干扰的有效手段。

| Abstract: | According to the deficiency of the conventional repeater jamming which only produces the spot jamming to ISAR,the ISAR scatter-wave jamming technique is presented in this paper.The intercepted radar signal is transmitted to target in this method,and the scatter-wave jamming signal is obtained by scattering of the target.The much more jamming information is included in the scatter-wave jamming signal than the conventional repeater jamming signal.Based on the imaging theory of the bistatic ISAR,the jammer and... |
