一种快速绘制干扰区域的算法

敌我双方的干扰态势分析是电子战辅助决策里面经常遇到的问题，干扰区域的绘制是作战态势系统中必不可少的一部分，尤其是掩护固定目标的干扰区域绘制。在掩护固定目标时干扰作用距离的解析表达式中含有超越方程，导致掩护固定目标的干扰区域绘制算法是作战态势系统中的一个难点。文中给出了一种在地理信息系统中快速绘制干扰区域的算法，重点是掩护固定目标的干扰区域绘制算法，原理简单，绘制快捷。

An Algorithm for Quickly Drawing Jamming Range

It is one of necessary part in battle situatio n analysis system to draw the jamming range, especially to draw the jamming range of protected stationary objects. Because the jamming equation of protected stat ionary objects is a transcendental equation, it is difficult to draw jamming ran ge of protected stationary objects. An algorithm is suggested having simple prin ciple and quickly which could be drawn in this paper.
