摘　　要：首先介绍了岸基条件下高频地波超视距雷达海杂波的产生机理 ,然后分析了舰载条件下海杂波的展宽现象及原因 ,最后对岸基和舰载条件下的海杂波进行了仿真 ,并与实际采集到的海浪回波进行比较 。The mechanisms of sea clutters received by a HF ground wave over the horizon radar fixed on shore are introduced. The phenomena and reasons of broadening of sea clutters in the condition of using a ship mounted radar are explained. Finally, the sea clutters for two situations are simulated, and the results are compared with real sea clutters so that the theoretical analyses are proved effectively.
