The effect of moving target on range-doppler map and backprojection algorithm for focusing

Range migration is unavoidable and cannot be neglected in pulse Doppler radar when target velocity is high and/or wideband transmit signals are used. In this paper, we investigate the range and Doppler degradation due to target motion in wideband pulse Doppler radar. To correct range cell migration, an alternative focusing method is introduced by using the backprojection algorithm. The success of the method is shown by simulations.
