提出了一种归一化函数作为研究城市雷达目标异质性的框架。该功能包括三种类型的尺度，目标的物理尺寸，介电常数的异质性，和目标的几何形状。以目标几何结构中的方位角或方位尺度为例，研究了建筑物方位角对雷达后向散射的影响。研究结果将推动SAR的应用和理论发展。
A normalized function was proposed as the framework to study the heterogeneity of urban radar targets. The function consisted of three types of scales, the physical size of a target, heterogeneity in dielectric constant, and target geometry. The azimuth direction or azimuth scale, one component of the target geometry was exampled to investigate the influence of azimuth orientations of buildings on radar backscattering. The results should advance SAR application and theory.
