Abstract: he superresolution range-doppler imaging method based on the linear prediction data extrapolation is simply described,and a special signal processor constructed with a high speed digital signal processing(DSP)chip TMS320C25 is presented which can perform the data extrapolation,weighting,and 128 complex- point FFT,and complete superresolution 2- D imaging. The imaging results of the live data of a B-52 model aircraft mounted on a ro-taing platform in a microwave anechoic chamber are given and compared.

Key words: radar imagery, linear prediction, digits-signal processing, microprocessor
