Qishen Wang · Information and Electronic Engineering · 2005
Linear frequency-modulated(LFM) signal is a kind of broadly applied non-stationary signal.In this paper,Gauss linear frequency modulation wavelet is selected as the base function to study LFM signal detection and parameter estimation based on WT-Radon Transform,then an algorithm for multi-component LFM signal detection and parameter estimation is proposed.Computer simulation results have validated the effectivity of this algorithm.
