It is well known that range resolution and cross-range resolution of range-Dop-pler imaging radars are related to the effective bandwidth of transmitted signal and the angle through which the object rotates relatively to the radar line of sight during the cohe-rent processing time, respectively. In this paper we describe an investigation wherein the resolution capability of range-Doppler imaging radars is extended well beyond the limitation imposed by the conventional FFT range-Doppler processing. The approach we adopted uses linear prediction for data extrapolation before performing Fourier reconstruction. Preliminary results of rotating platform imaging based on experimental data acquired in a microwave anechoic chamber show that this technique is promissing in application to improve the resolution capability of range-Doppler imaging radars.
