摘要
雷达信号脉内调制识别是雷达侦察的一个重要内容,基于瞬时频率的识别技术可以实现对多种调制类型信号的识别及参数提取,该方法在一定信噪比条件下有较高的正确识别率,算法也较为简单,适合在雷达对抗侦察数字接收机上高速实现,分析表明此方法是侦察雷达信号的有效手段。
Radar signal in pulse modulation identification is the important content of radar reconnaissance. Multiple type modulation signals can be identified and the modulation parameters can be extracted by the instant frequency identification technique. Under certain signal to noise ratio,this method has high identification ratio. It is suitable for high speed realization in the radar reconnaissance digital receiver,because it has a simple algorithm. The results indicate that they are effective for detecting the radar signals.
