摘要
利用实验室内海环境模拟系统,在造波水池内模拟生成满足海谱分布的海浪,测试获取近距离窄波束照射条件下海面后向电磁散射回波数据,统计分析了模拟海面散射系数与入射角、方位角、测试频率等的关系.测试结果表明,在近距离窄波束照射条件下,海面后向散射信号起伏更加剧烈,散射情况更加复杂.
A series of backward scattering measurements simulating rough sea sur- face were conducted over a wave pool. The rough water simulated a one dimensional Pierson Moskowitz surface. The scattering factor were analyzed with incident angle and frequency. The compiled data represent more fluctuant and com- plicated when the rough sea surface were illuminated by narrow beam width horns in near field.
