New methods for fast estimation of target's motion parameter
Baojun Zhang · Computer Engineering and Applications Journal · 2011
A new method of motion parameter estimation for Constant Wave(CW) radar is addressed.The echo signal of CW radar is separated into two sine signals by a novel signal transform,and the frequency of each sine signal is due to one of motion parameter for target.Moreover,this method takes advantage of the frequency estimation algorithm based on Chirp-Z transform and Fast Fourier Transform(FFT).Compared with other methods,due to without complex processing such as time-frequency analyzing and two-dimension searching,and without iterative processing,the proposed algorithm costs less runtime and avoids error passing.The validity of this method is shown in the simulation results.
