摘　　要：为了提高雷达操纵员训练效果,解决手工绘制航线曲线不平滑、校点不精确等问题,采用拉格朗日插值算法,使记录的坐标点数组按插值的方式进行均匀化,提高校点精度;通过对话框方式和两种显示模式,简化了航线合批处理与航线绘制的复杂度;调用C#GDI+中的绘制函数绘制航线,保证航线平滑,提高雷达航线制作的效率.To improve the radar operator’s training efficiency and solve the problems of hand-drawing flight course curves being not smooth and calibrated points imprecise, this paper employs Lagrange interpolation algo-rithm and homogenize the recorded coordinate points array in terms of the interpolation approach to enhance the precision of the calibrated points. By dialog mode and two sorts of display modes, the flight courses processing in the batch and the complexity of flight courses-drawing are simplified, the drawing function in C# GDI＋are called to draw the flight course to guarantee the course is smooth, which improve the efficiency of radar flight course drawing.
