In view of the strong out-of-window scatterers,an adaptive filter based on minimum mean square error (MMSE) criteria is employed to estimate the high range resolution profile of the extended target.This approach estimates the amplitudes of each range cell in an iterative way.A simulated performance comparison is made between the Reiterative-MMSE (RMMSE) algorithm and the matched filter and least-squares (LS) algorithm.Simulation results show that the algorithm can estimate the amplitudes of the multiple scatterers effectively.

Key words: minimum mean-square error(MMSE);adaptive filtering;extended target
