| 摘 要： | 高频雷达工作的波段十分拥挤,因而可用的连续带宽比较窄,雷达获得距离分辨力极为有限.为避开干扰频段能够提高系统带宽,本文采用了一种频带不连续的准随机跳频信号.并根据信号的特点,系统地提出了该信号的二维信号处理方案.仿真表明,这种方案具有解距离-速度模糊的能力,能有效地抑制最大距离旁瓣,较好地实现了距离速度二维分辨.

| Abstract: | Due to the heavy congestion in HF bands,HF radars are restricted to operating within very narrow bands,thus obtain a poor range resolution.A quasi-random step frequency signal with discontinuous bands is presented to improve the system bandwidth while avoiding the heavy interference bands.A two-dimension signal processing scheme for this signal is proposed on the basis of signal analysis.Simulation results demonstrate that the scheme could decouple the range-Doppler ambiguity,thus successfully realize the range-Doppler resolution and effectively suppress maximal sidelobe. |

| Keywords: | random step frequencies sidelobes suppression signal processing |
