Zusammenfassung:Doppler distortion degrades the performance of the reiterative minimum mean-squared-error (RMMSE) adaptive pulse compression (APC) algorithm. This paper presents a new approach for robust RMMSE Doppler compensation through the use of covariance matrix tapers (RMMSE-CMT). RMMSE-CMT delivers performance comparable to the existing approaches such as Doppler-compensated APC (DC-APC). RMMSE-CMT is simple to implement and offers considerable computational savings over DC-APC. RMMSE-CMT also provides improved Doppler robustness in the fast-APC algorithm.
