Abstract
In this paper,the instantaneous frequencies of three typical pulse compression radar signals were analyzed:linear frequency modulation signal,phase coded signal and frequency coded signal;the identification method based on instantaneous frequency characteristics was given.The simulation results showed that this method can effectively obtain the types of Intra-pulse modulation.In order to improve the real-time and accuracy of electronic reconnaissance system,the implementation of Intra-pulse modulation recognition was studied,and the real signal test was passed.
