根据中频带通采样雷达噪声频谱在线监测方法，实现环境噪声和外部干扰频谱在线监测。该文研究了在获得噪声频谱基础上，使用非线性优化方法获取雷达优质工作频率或频段，实现高频雷达工作频率在线实时优化选择。使用浙江舟山实验数据进行频率／频段在线寻优处理，为雷达选择优质工作频率或频段提供了依据，证明方法可行。

According to method inspecting on-line of noises spectrum in the IF-sampling radar.Realised that inspecting noises and interference of environment on-line.In this paper, researched into the method of nonlinear optimization for obtained optimal HF radar work frequency,finished to optimize HF radar work frequency on-line real-time .The method is used to HF ground wave radar system in ZhouShan ZheJiang China.First,the noises spectrum is obtained on-line ,next the optimal work frequency is selected for the HF ladar,proved that this method is right.
