Abstract
According to the high complexity of extracting feature of radar signal using image processing method,a new method for extracting feature was proposed.Firstly,the time-frequency distribution was gained based on the adaptive Gaussian kernel time frequency analysis,then through analyzing the physical meaning of each element,one dimension vector could be found through a simple arithmetic instead of the complicated method through processing the time-frequency figure with image processing means,so the real-time requirement for sorting radar signal could be satisfied.The simulation results verify the efficiency of the proposed algorithm.Additionally,the accuracy can be kept at a high level while the Signal-to-Noise Ratio(SNR) is low.
