Novel Method of Velocity Estimation of LFMCW Radar

摘要

To reduce the influence of range-velocity coupling of LFMCW radar echo signal on range measuring, a novel method of velocity estimation has been proposed, based on the response equation of moving targets under wideband LFMCW stimulation. In this method, velocity of spatially distributed targets with several dominant scattering centers is estimated. According to the estimated velocity, the algorithm of motion compensation (MC) of range measured and range image is presented. The effectiveness and feasibility of this method are proved by the results of computer simulation.
