摘　　要：舰载超视距雷达 (Over-The -HorizonRadar:OTHR)对于提高现代舰船的预警和生存能力具有重要意义。但由于干扰信号、时变非线性信道、强杂波背景的综合影响 ,使得OTHR信号处理的各个环节存在诸多困难。在总结舰载OTHR信号处理所面临诸多挑战的基础上 ,本文着重分析了舰载OTHR杂波谱展宽及相应对策 ,得到并指出了可行的解决方法。Shipborne Over-The-Horizon Radar (OTHR) is an essential kind of equipment for warship to improve the performances of the early warning and survival. However,due to the integrated effect of the jamming signal,time-varied and non-linear signal channel and strong clutter background,many difficulties and problems are inevitable for shipborne OTHR indeed. Based on the emphasized analysis of the spread clutter spectrum of the shipborne OTHR,the applicable approaches are provided to improve the signal processing performance in this paper.
