摘　　要：短波电台干扰是高频地波雷达的主要干扰源,通过建立了各种短波电台干扰的理论模型,系统分析了干扰信号的频谱特性,并进行了实际雷达干扰信号的频谱分析研究,得出了干扰信号的典型频谱特征,实验和仿真结果证明了理论的正确性,从而为高频地波雷达的干扰抑制、目标检测和海态特征的研究提供了理论和试验依据.The short-wave radio disturbances constitute the dominant interference sources of HF surface wave radar. The mathematic models of the short-wave radio disturbances in HF surface wave radar are established in this paper. Then the features of the frequency spectrum of the disturbances are analyzed in detail. Some real disturbance signals in a real HF radar are processed to show the correctness of the models. The results found the basis of the study on disturbance suppression, target detection and features of sea state.
