  • The Superresolution mehtod based on the models of both the signal and the noise leads tO a superior accuracy thah the FFT method.This paper presents applications of superresolution signal estimatiors to Doppler beam sharpened imaging and proposes a method for target feature extraction.Experimental results show that the imaging quality are superiorhan that of traditional FFT method.
