Abstract

A new method for linear FM (LFM) signals detection in the time-frequency plane using Teager-Huang Transform (THT) is proposed. Time-Frequency Representation (TFR) is viewed as an image where image processing techniques are applied to detect frequency patterns of interest. THT is used in conjunction with Hough Transform (H_gT) called (THHT), where the output is a TFR free of cross-terms. THHT is applied to signals composed of LFM and the results are compared to Wigner-Ville Distribution-H_gT and smoothed Wigner-Ville Distribution-H_gT. Results show the good performance of the THHT in terms of detection and estimation compared to WVD based methods.
