【摘要】 简要介绍线性预测数据外推的超分辨距离－多普勒成象方法，并以一片高速数字信号处理（ＤＳＰ）芯片—ＴＭＳ３２０Ｃ２５为核心设计了一个专用信号处理器，能完成数据外推、加窗和１２８复数点ＦＦＴ，实现超分辨二维成象。文中给出了对Ｂ－５２模型飞机微波暗室转台实测数据的成象结果，并作了比较。更多还原

【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.更多还原
