利用卫星定位数据计算红外探测系统的作用距离

Calculating Operation Range of Infrared Detection System with Satellite Positioning Data

介绍了一种根据卫星定位数据给出的经纬度信息,计算两点之间直线长度距离和最短弧线长度距离的方法。红外探测系统与目标之间的作用距离是一条直线的长度。根据两者的经纬度信息可以算出它们之间的距离。当红外探测系统与目标中有一方在运动(例如地对空、空对地)或者两方都在运动(例如空对空)时,使用该方法或可计算出红外探测系统的作用距离。

A method for calculating the straight length and the shortest arc line length between two points according to the longitude and latitude information given by satellite positioning data is presented. The operation range between an infrared detection system and a target is the length of a straight line. It can be calculated according to the longitude and latitude information of the infrared detection system and the target.If either of the infrared detection system and the target is moving（e.g.ground-to-air or air-to-ground） or both of them are moving（e.g.air-to-ground）,the operation range of the infrared detection system can be calculated by using this method.
