论红外成像系统的最大作用距离

作用距离是描述军用红外成像系统整机性能的一个重要参数。作用距离可以分为探测距离、识别距离和确认距离,其中以探测距离最大。根据红外成像系统、地球曲面和目标之间的几何关系,介绍了一种基于MATLAB的对地观察红外成像系统的最大作用距离计算方法。该值取决于整机所在高度、地球半径和目标高度。整机的实际探测距离或者对待研整机提出的作用距离指标不应该大于此值。

On the Maximum Operation Range of an Infrared Imaging System

The operation range is one of the important parameters for describing the whole performance of a military infrared imaging system. It can be divided into detection range, recognition range and identification range among which the detection range is the maximum one. According to the geometric relationships among the infrared imaging system, the earth surface and the target, a method for calculating the operation range of an earth observation infrared imaging system based on MATLAB is presented. The value of the operation range is determined by the altitude of the infrared imaging system, the radius of the earth and the height of the target. The actual detection range of an infrared imaging system or the operation range proposed for a system to be developed should not be greater than this value.
