Abstract
A fast algorithm for estimating the parameters of a LFM signal is presented in this paper. This algorithm is based on the fact that the WVD of a LFM signal concentrates along the instantaneous frequency, and can be implemented by estimating the frequencies at different time positions, hence, the chirp rate and the initial frequency can be obtained. The proposed algorithm is fast in that it requires only one-dimensional maximizations. The statistical performance of this algorithm is analyzed, and the theoretical expressions of the mean square error (MSE) of the parameters are obtained. Then the algorithm is extended to estimate the parameters of a polynomial phase signal. The computer simulation results demonstrate the validity of the algorithm proposed.
