COMPUTER SIMULATION STUDY OF A RADAR DOPPLER PROCESSOR USING THE MAXIMUM-ENTROPY METHOD.
Abstract
The paper describes the use of the maximum-entropy method to estimate the Doppler shift of a moving target in the presence of additive white noise or colored noise consisting of clutter plus white noise. Computer simulation results are included which show that in a background of additive white noise a Doppler processor based on the maximum-entropy method is only slightly suboptimal with respect to a conventional Doppler processor based on the discrete Fourier transform, whereas in the presence of additive clutter with a narrow spectral width (e. g. ground clutter) it is superior to the conventional processor for the case of low Doppler targets.
