Abstract

In view of accurate estimation of motion parameters for the stepped frequency radar's targets, chirp-Fourier transform method was resented to estimate target's velocity and acceleration. Based on the analysis of uniformly accelerated motion's influence on the target range profile, the target's acceleration and velocity were estimated accurately by the method of the direct phase difference and chirpFourier transform to achieve accurate compensation of target's motion. Finally, the simulation results proved the validity of the method. It also has a certain anti-interference ability.

Key words： motion compensation; first-order difference; chirp-Fourier transform; acceleration
