摘　　要：提出一种应用Radon Ambiguity变换来检测识别反辐射导弹的新方法,该方法不需要对导弹加速度进行多通道相位补偿预处理,对导弹信号的检测通过一维搜索完成,计算量小,同时对调频率识别比较准确.仿真结果显示,该方法能够在导弹信噪比达-10dB的背景中将微弱的导弹信号准确地检测识别出来.A new method for ARM detection and identification based on RAT (Radon-Ambiguity Transform) is proposed, by which no multichannel phase compensation preprocessing for missile acceleration is required. The detection of ARM signal is accomplished by one-dimensional searching and hence the computation is greatly reduced. Meanwhile the chirp rate identification is more accurate. Computer simulation shows that an accurate and reliable detection and identification of weak ARM signals can be achieved in the SNR environment as low as -10 dB.
