| Abstract: | An approach is presented for the implementation of real time adaptive radar clutter cancellation systems. In order to control coefficients of FIR prediction error filter (PEF), the criteria of least mens square error (LMS) and modified least root mean square error (MLMS) algorithm are analyzed. System performance simulation eaperiments were implemented . A prototype adaptive moving target indicator (MTI) system is developed, built upon DSP chips. It has good adaptive cancellation performance for ground clutter and moving clutter. The measured improvement factor is more than 20 dB in a radar system. |
