海环境近区电磁散射特性模拟测试及统计分析

Electromagnetic backwardscattering measurements of rough sea surface in near field

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.

Abstract: A series of backward scattering measurements simulating rough sea surface were conducted over a wave pool. The rough water simulated a onedimensional PiersonMoskowitz surface. The scattering factor were analyzed with incident angle and frequency. The compiled data represent more fluctuant and complicated when the rough sea surface were illuminated by narrow beam width horns in near field.
