| 摘 要： | 雷达信号频率是接收机进行信号分选的一个重要参数。分析了比相法瞬时测频(IFM)接收机的组成和测频原理,针对同时到达信号对IFM接收机测频结果的影响,从雷达反侦察角度出发,提出用步进频率连续波信号对接收机进行干扰来破坏其正确测频结果,并进行仿真分析验证了干扰效果。

| Abstract: | Radar frequency is a primary sorting parameter of signal sorting. The structures and principle of instantaneous frequency measure of IFM receiver is analyzed. Based on the effect caused by signals arriving at same time to the correct result of IFM ,SFCW signal is presented and analyzed to jam IFM receiver. The simulated results prove that the jamming technique is effective. |
