镜像抑制比的高低直接影响雷达对抗侦察接收机的性能。利用正交混频原理，设计实现了镜像频率信号消隐技术，用于对雷达对抗侦察装备镜像频率信号的抑制。该技术相比以往的镜像频率信号抑制方法，具有设备量小、速度快、可实现高镜像抑制比的特点。最后制作了镜像频率信号消隐模块样机。测试结果表明了该技术的可行性和有效性。

The high or low of image rejection rate influences directly on the performances of radar countermeasure reconnaissance receiver. By taking the principles of quadrature-mixing, this paper designs a type of image frequency signal blanking scheme and implements it, which can be used for suppressing the image frequency signal radar countermeasure reconnaissance system. This technique proposed has some advantages over small amount of equipment, fast speed, available for high image rejection rate, compared with the traditional suppressing one. And finally, the model machine with image frequency signal blanking module is made. The test results indicate that this proposed technique is of feasibility and effectiveness.
