It is found that there exist "amplification" and "self-compensation" of beam spread in the reflection from a mirror and a corner cube reflector, respectively.
证实了平面镜反射光束的扩展存在放大效应，角反射器反射光束的扩展存在自补偿效应。

The emphasis in this paper was corner reflector antenna with high-gain, narrow beam and low side-lobe.
选用方向性好、增益高、旁瓣低的角形反射器天线作为本论文的研究重点。

Based on geometrical optics formulation, this paper deals with the problem of Angle of arrival influence of reflected beam by a reflector, and derived the expression of Angle of arrival variance.
