基于海面脉冲回波数据的散射系数获取方法

摘要

利用挂飞测量采集到的动态海面脉冲回波数据,先根据测试雷达的脉冲参数和天线增益,对海面照射区做网格划分,计算加权的有效海面面积。再统计对应的海面回波平均功率,获取一定入射角范围内的海面散射系数,结果与一些前人的测量结果较为吻合。%A large amount of dynamic pulse echo data of sea surface was collected during the embarkation flight measured.According to the radar pulse parameters and the gain of the antenna,the weighted effective area of sea surface was calculated by meshing the irradiated zone.Using the corresponding average echo power of sea surface acquired by the statistical method,the scattering coefficient of sea surface within a certain range of incidence angles was obtained.The results agreed with the measured results of some predecessors well.
