摘　　要：箔条干扰是影响雷达命中精度的重要因素,但常规抗箔条假目标干扰方法不适用于对海跟踪雷达使用。鉴于箔条假目标干扰和舰船目标有明显不同的去极化特性,对箔条假目标干扰的极化识别与抑制技术进行了研究,定义极化比为干扰鉴别量,分析并优化设计了箔条假目标干扰极化识别与抑制方案,为研究高性能的对海跟踪雷达提供了新思路。Chaff decoys is an important factor that impacts the hit accuracy of antiship missile terminal guidance radar, but the conventional method of antijamming of chaff decoys is not appli- cable in the use of antiship missile terminal guidance radar. Considering that the chaff decoy and ship＇s target has different polarization, now study a technology of polarization identification and suppression of chaff decoys, define polarization ratio as an identify quantity, make analysis and de- sign the identification system of the polarization of chaff decoys, in order to provide a new clue for studying high-performance of antiship missile terminal guidance radar.
