摘　　要：高频地波雷达探测目标时是通过监视外部噪声电平来选择工作频率,其缺点是无法达到最佳的目标检测性能。为解决该问题,文中基于高频地波雷达方程分析了影响目标检测性能的各种因素,提出一种通过目标信噪比(信杂比)与工作频率之间关系的仿真计算来选择工作频率的方法。运用该方法选择工作频率能够获得较好的目标检测性能,并针对高频地波雷达探测不同类型目标时的频率选择问题进行了仿真及结果分析,并得出了相应的结论。Because the operation frequency of high frequency surface wave radar （HFSWR） for target detection is selected by the monitoring of outside noise level, the optimal detection performance can not be achieved. To solve the problem, the multiple factors that affect the target detection performance are analyzed based on HF surface wave radar equation, and then a frequency selection method is presented by numerical simulation to calculate the relationship curve between SNR （SCR） and frequency. With the op- eration frequency selected by this method, the better detection performance can be achieved. Then the author implemented the simulation for different kinds of targets detection, analyzed the simulation results, and made corresponding conclusions.
