摘要 利用海上蒸发波导可以使舰载微波超视距雷达实现远距离低空目标探测,然而大气波导内的超折射和多径传播效应会产生不利于目标检测的雷达盲区。该文提出一种基于目标函数的微波超视距雷达天线高度优化方法,针对形成蒸发波导的海-气界面稳定层结、中性层结和不稳定层结3种情况,利用电波传播数值算法和雷达评估模型仿真分析了蒸发波导内特定区域不同目标函数时的雷达目标检测性能,给出了雷达天线高度优化结果。该文方法可以为微波超视距雷达系统设计、探测性能分析和大气环境自适应技术提供参考。 Microwave over-the-horizon radar can detect long distance and low altitude targets by means of the evaporation ducts over sea, however, the super refraction and multi-path propagation effects produce radar blind areas in evaporation duct where targets can not be detected. A method of antenna height optimization based on object function for microwave over-the-horizon radar is proposed in this paper. Radar detection performances are simulated in the three evaporation duct situations of stable stratification, neutral stratification and unstable stratification using numeric algorithm of radiowave propagation and radar performance evaluating models. The results of optimized antenna height is obtained for specific evaporation height and area weight functions. The method proposed can be used as a reference in microwave over-the-horizon radar design, detection performance analysis and self adaptive technology development in atmosphere environment.
