Abstract: In wideband radar,high-velocity targets usually move through several range resolution cells,which is troublesome to estimate target’s velocity.An accurate velocity-measurement method for wideband PD radar based on keystone transform is proposed.The method can deal with target’s range migration and target’s Doppler spectra broadening.The simulation shows that it can achieve very accurate velocity estimation.So the method is very practical in wideband radar.
