摘要
空中目标监视系统在处理目标位置过程中会产生大量的距离、角度运算,目前国内的系统多采用投影公式把地球椭球模型投影到平面上,得出平面直角坐标系,在系统中使用平面直角坐标系,便于计算和界面显示。其中高斯-克吕格投影(简称高斯投影)是一种重要的投影方法,应用很广泛,文章重点研究该投影方法及产生的投影误差,以及投影误差对空中目标监视系统的影响,同时提出一些解决方法供参考。
The air target surveillance system will produce a lot of distance,angle calculation in dealing with the position of the target in the process,the current domestic system using the projection formula of the earth ellipsoid model is projected onto the plane,that plane rectangular coordinate system,using the plane right angle coordinate in the system,easy to calculate and display interface.The Gauss Kruger projection(the Gauss projection)is a kind of important projection method,is also widely used,projection error research and produce the projection method this paper focuses on the influence of air targets,the projection error monitoring system,puts forward some solutions for reference.
