摘要
本文讨论了地物空间相关特性的测量，所用测量设备为Ｘ、Ｌ波段调频连续波散射计。实验结果表明：所测陆地回波空间相关特性与极化关系不大；地物空间相关距离随入射角增大而增大；空间相关函数可用Ｇａｕｓｓ函数与负指数函数之和表示；Ｌ波段电磁波比Ｘ波段电磁波有更强的植被穿透能力。
A measurement was made for spatial correlation characteristics of land radar clutter with two FM-CW scatterometers at X and L band respectively. Some results are shown in this Paper. 1. The derived spatial correlation characteristics of land clutter is weakly related to polarizatios. 2. Spatial correlation length of land clutter becomes longer with the increase of incident angle. 3. Spatial correlation function can be approximated with the summation of Gauss and exponential functions. 4. L band electromagnetic waves are capable to penetrate much deeper into vegetation than those at X band.
