一种基于Keystone变换的运动目标相参积累方法
An Algorithm for Moving Target Coherent Integration Based on Keystone Transform
摘要
Abstract
According to the background of wideband linear frequency modulated continuous wave (LFMCW) radar,the range-walk and Doppler-broaden features of moving target are studied on long time coherent integration.By giving the corresponding explicit functions of range-Doppler broadening acreage and signal-to-noise ratio loss,an optimization algorithm is proposed based on rangeDoppler two-dimensional least waveform entropy.Then combining with the Keystone transform and CLEAN algorithm,coherent integration for moving target flowed in strong clutter background is studied.Finally,simulation results are presented to verify the effectiveness of the proposed method.关键词
