Abstract :
In this paper, a new technology for compensating the defocus due to the velocities of multiple moving targets is presented. By using this technology, the blur produced by defocus can be compensated when the velocities are unknown. And a method is proposed to solve the range-Doppler coupling caused by the multiple targets. The effectiveness of the algorithm is illustrated with simulation results.
