摘要 雷达侦察设备通常采用闭锁措施消除移动通信频段的同频干扰,严重降低了脉冲截获概率,且极易被敌方雷达利用。针对此问题,提出一种基于极化滤波的移动通信信号抑制方法,该方法依据移动通信信号与雷达信号极化差,设置合理的极化滤波矢量,在极化域滤除移动通信信号,提高了移动通信频段的脉冲截获概率。给出了极化滤波侦察接受机的设计方案。仿真实验结果验证了该方法的有效性。 Radar reconnaissance equipment usually uses locking measure against the interference of mobile communication signal in the communication frequency. This measure would decrease the pulse acquisition probability, and easily be utilized by the enemy. Therefore, a polarization filtering method is proposed to suppress the mobile communication signal interference. The method firstly sets the polarization filter based on the polarization difference between the radar signal and the mobile communication signal. And then, the mobile communication signals are filtered out in the polarization domain. The design scheme of the polarization filter reconnaissance receiver is also given. The simulation result has proved the effectiveness of the proposed method.
