%X This paper presents a multi-frame stepped-frequency signal processing method to detect moving targets, and a Doppler bin alignment method is proposed to compensate the image aliasing caused by moving targets. This method makes use of the relationship of Doppler bins among different sub-frequencies and can realize the velocity compensation of moving targets via the rearrangement of Doppler bins and phase compensation. This algorithm can simultaneously compensate the effects of linear range migration for all moving targets without knowing their unknown velocity. Analysis and simulation results show that this processing can image the range and velocity of moving targets simultaneously with stepped-frequency signals and can be applied easily because of its computational efficiency.
