Abstract
A LFM signal detection algorithm based on empirical mode decomposition and Wigner-Hough transform is put forward. The main interference component is found and eliminated through EMD. According to principal signal separation SNR of target component is increased. Through Wigner-Hough transform the energy of LFM signal is concentrated in a peak. Simulation result shows the detection algorithm is effective and target is detected in low SNR.
