Abstract

Abstract: In this paper, we present three different kinds of motion compensation methods for stepped frequency radar, which are time domain compensation method, frequency domain compensation method and mini entropy compensation method.Then, an improved method by combining the first two methods is provided. The HRR image at various look angles and ratios of signal to noise is recognized by Linear Interpolation Neural Network and the result is very satisfactory.

Key words: motion compensation, high r ange r esolution(HRR), AT R
