我们分析了金属立方体和平板在实验性高分辨力二维雷达图象呈现的散射中心的极化特性。对每一散射中心,我们确定了特征角γ和目标跳跃(skip)角v与目标姿态角°θ和频率之间的关系曲线。我们发现:(1)立方体:仅考虑往返立方体边缘的一次波的传播的几何绕射理论模拟就描述了实验结果。 (2)平板:对于与窄面相关连的散射中心,在γ到达最大值的f_。上ν改变符号。考虑更高次散射的几何绕射理论模拟,可比较好地与实验吻合。
We analyze the polarization characteristics of the scattering centers exhibited by metallic cubes and plates in experimental high-resolution 2D radar images. For each scattering center, we determined the relationship between the characteristic angle γ and the target skip angle v and the target attitude angle θ and frequency. We found that: (1) Cube: The experimental results are described by a geometrical diffraction theory simulation that takes into account only the propagation of the primary wave from the edge of the cube. (2) Plates: f_ at maximum for γ for the scattering center associated with the narrow face. On ν change the symbol. Considering the geometry diffraction theory of higher scattering, it can be well matched with the experiment.
