Research into a Suppression Method Based on Random Agility of PRF to Slice Combination Interference

切片组合干扰同时兼具压制和欺骗干扰的特点,对雷达的目标检测造成巨大威胁。提出一种基于重频随机捷变的切片组合干扰抑制方法,并对基于重频随机捷变的切片组合干扰抑制方法进行了理论分析,最后进行数值仿真。该研究对于提高反舰导弹末制导雷达的抗干扰能力具有一定的参考意义。

The slice combined jamming has characteristics of both suppression jamming and deception jamming,which poses a great threat to radar target detection.In this paper,a method of slice combination interference suppression based on random agility of pulse repetition frequency(PRF)is proposed,then the method of chip combination interference suppression based on random agility of PRF is analyzed theoretically,and the numerical simulation is carried out finally.The research has definite reference significance for improving the anti-jamming ability of anti-ship missile terminal guidance radar.
