Detection and Parameter Estimation of Multicomponent LFM Signal Based on the Cubic Phase Function

Detection and Parameter Estimation of Multicomponent LFM Signal Based on the Cubic Phase Function

A new algorithm for the detection and parameters estimation of LFM signal is presented in this paper. By the computation of the cubic phase function (CPF) of the signal, it is shown that the CPF is concentrated along the frequency rate law of the signal, and the peak of the CPF yields the estimate o...
