摘　　要：为了提高高频地波雷达的抗干扰性能,用几个不连续的干净频带来合成系统的有效带宽。为了抑制频谱不连续造成的高距离旁瓣,采用正则化内插/外推算法进行距离速度二维处理;仿真结果表明,该方法不仅能有效地抑制距离旁瓣,而且还能实现目标的距离-速度超分辨。In order to improve the performance of HF ground wave radar for antijamming, the system band is synthesized of several discontinuous clear frequency bands. To suppress the range sidelobes due to discontinuous spectra, the paper proposes a range-velocity processing method based on regularized interpolation/extrapolation. The simulation results show that the method can not only suppress the range sidelobes efficiently but also realize the range-velocity super-resolution successfully.
