摘要
Abstract
With the wide application of complex modulated compression radar signal, traditional identification method can’t sat-isfy the need of modern electronical reconnaissance. Aiming at this problem, an identification method based on the Generalized Time-Frequency Representation of Zhao, Atlas and Marks(ZAM-GTFR)and Radon transform is put forward. After carry out ZAM-GTFR and Radon transform on signal, this method makes use of the optimal rotational angle and number of summits to identify signal. This method can identify many kinds of complex modulated compression radar signals, including sinusoid fre-quency modulated signal and poly-phase modulated signal. Simulation results verify that correct identification ratio of this meth-od can reach 94%when signal-to-noise ration is -3 dB .关键词
