一种针对雷达多普勒测速系统全面干扰的方法

A Kind of Interference Method Directly against Radar Speed Determining System

由于现代雷达经常运用距离选通波门来排除外界针对雷达多普勒测速的干扰,因此,本文提出以干扰雷达的距离波门的方法来配合对雷达的多普勒测速系统的干扰,找出了两种干扰之间的对应参数关系,讨论了应用多普勒拍频对雷达进行干扰时应该注意的问题,并得出了重要结论。现代军用雷达里很普遍的一种信号形式就是脉内线性调频,本文主要是对采用这种信号形式的雷达速度跟踪系统的干扰进行讨论。

Because modern radar often makes the method of distance determination wave gate to eliminate the interference directly against radar speed determination system, this paper advances the method that matches the interference directly against radar speed determination through the interference directly against radar distance determination. The paper gets the relation between the two interference parameters, discusses the problem that we should pay attention to if the beat frequency is made use of to interference, and gets very important conclusion. In modem radar, a kind of very important signal pattern is linear frequency restructure. The paper is discussed directly against this signal pattern.
