| 摘 要： | 蒸发波导是海洋大气环境中一种常见的异常折射结构,它能够陷获电磁波并改变电磁波的传播轨迹,进而影响雷达对目标的探测性能。主要通过构建雷达性能评估的仿真模型和方法,利用仿真的结果分析了蒸发波导环境中雷达的异常探测特征。首先介绍了基于电磁波传播的抛物数值方程以及裂步傅立叶算法技术的雷达探测评估方法,应用这一方法对不同蒸发波导环境下雷达的探测进行仿真计算,分析了由于大气波导环境的影响所产生的雷达低空异常探测特征。

| Abstract: | Evaporation duct is a familiar abnormal structure of atmospheric refractivity,which has important influence on radar performance.To evaluate the capability of radar in evaporation duct environments,a model was proposed based on the parabolic equation numerical model of electromagnetic waves propagation and radar receiver theory.The proposed model was used to simulate the radar detection in different evaporation ducts conditions.And the anomalous characteristics of radar detection were analyzed according to the results of simulation. |
