摘　　要：在对LFM信号实现分选的基础上,选取待识信号的瞬时频率作为识别特征,利用最近邻方法对信号进行识别。实验结果表明,在一定的信噪比条件下能达到较理想的识别效果。该方法原理简单,运算量小,能够满足工程中实时性的要求。Supposing the LFM signals had been sorted and selecting the instantaneous frequency as identification character,the closest method is used to distinguish the signals.Simulation results show that satisfying recognition effect is got in some condition of SNR.The theory and calculating of the method is simple,which can satisfy the request of engineering application.
