| Abstract: | 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. |
