A Novel Method for Eztraction of In-Pulse Feature of Multi-Component LFM Signal

摘要：

Aiming on the problem of low precision and cross term in the conventional method of multi-component LFM signal detection and parameter estimation. A timefrequency associated analyzed method based on wavelet transform and time-frequency reassignment and Hough transform is proposed. Overcome the interferences of cross term by wavelet transform, guarantee the accuracy by time-frequency reassignment, use the distribution of time-frequency after reassignment as the image, then achieves the interception of component and the estimate of parameter based on Hough transform. Simulation results show that this method is feasible.
