探测器组盲区CAD分析与重叠角计算公式

The CAD Analysis Used for the Blind Zone of a Set of Detectors and the Formula of Calculating Over-lapping Angle

本文目的是计算探测器的盲区。文中提出了一种圆锥体与球体相贯求官区的方法；用ＣＡＤ技术给出了直观图和精确的数据。最后，推导了方位视场重叠角的计算公式，并验证之。

The aim of this paper is to calculate the detector′blind zone. A sort of new method using the intersection of solid cone and solid sphere is presented.By means of CAD technique,the visual solid modeling and the exact data can be gotten,Finaly,the formula of calculating over-lapping angle for azimuth view field has been derived and verified.
