X波段测波雷达海流信息反演的影响因素分析
|
Abstract:
X波段测波雷达海流信息的提取决定着有效浪高结果的准确度。因此，对可能影响X波段测波雷达海流信息提取的各种环境因素以及雷达工作模式等进行了海浪回波成像仿真，然后采用目前测波雷达通用的算法对仿真回波图像进行了海流信息反演。主要研究了海表面风速、雷达天线架设距离海平面高度、天线转速、海流流速、海流流向与海浪方向夹角、所选取的图像帧数以及每帧图像大小对海流信息反演的影响。对比分析设定值与反演结果，可知海表面风速在6~14 m/s之间，天线高度大于20 m并且转速为50~70 r/min，流速小于200 cm/s并且主波浪向与流向夹角不接近90°，图像帧数为128帧并且每帧图像数据点数为128×128时，X波段测波雷达能获得最佳海流信息反演结果
