摘要
旁瓣匿影是脉冲压缩雷达中常用的抗干扰技术。首先基于旁瓣匿影的一般结构,构建了脉压前匿影与脉压后匿影两种工作模式。然后重点针对不同工作模式下的雷达抗干扰性能和检测性能进行了理论分析和仿真研究。结果表明,脉压前匿影比较适合对抗压制性脉冲干扰,而脉压后匿影则更适合对抗欺骗性脉冲干扰。
Sidelobe blanking is a normal technology in pulse-compression radar. The operating modes of blanking before and after pulse-compression are builded, depending on the common structure of sidelobe blanking. Then,the anti-jamming performance and detectability in different operating mode are analyzed deeply with theories and simulation. The results indicate that blanking before pulse-compression is suitable to resist suppressive jamming,while blanking after pulse-compression performs better on deception jamming.
