Signal Processing Techniques for Radar Reconnaissance System Based on Time-frequency Analysis

The complex non-stationary signals are most often used in modern radar and communication systems.It must perform the tasks of envelope detection and intra-pulse feature analysis for radar pulse classification and identification.Time-frequency analysis is an effective tool for modern signal processing,and often applied to analyze and process non-stationary signals.Several methods of time-frequency analysis are presented,and their applications in the radar signal reconnaissance are also discussed and simulated.Simulation results show the effectiveness of these methods.
