The distributed source results from too many multipaths that are induced by reflection, scattering, diffraction and refraction from objects in complex environment and couldn't be described discriminatingly. Thus the source arrives at array antennas in a continual angular extension.

分布源的存在，主要是因为复杂环境下的目标反射、散射、衍射和折射导致大量信号路径存在，而又不可能对每条多径给予描述，从而造成目标空间位置在一定角度范围内连续分布，引起信号到达阵列天线的波前相干损失。
