A Radar Coverage-Diagram Drawing Method of Ground Netted Radar Based on Modified DEM

针对雷达组网威力图绘制问题,研究一种基于修正数字高程模型(DEM)的地面组网雷达威力图绘制方法。首先,按照地球曲率对DEM模型进行修正;其次,提出一种单部雷达威力图绘制方法,并对多部雷达威力图进行融合处理,达到绘制地面组网雷达威力图的目的;最后,通过仿真验证修正DEM模型的准确性以及组网雷达威力图绘制方法的有效性。

Aiming at the problem of drawing coverage-diagram of netted radar,a method of draw-ing netted radar coverage-diagram based on modified Digital Elevation Model(DEM)is stud-ied.According to the curvature of the earth,the DEM model is modified.On this basis,a meth-od of drawing coverage-diagram of single radar is proposed,and multiple-radar’s coverage-dia-grams are fused,which achieves the project of drawing coverage-diagram of ground netted radar.Finally,the accuracy of the modified DEM model and the effectiveness of the method of drawing the coverage-diagram of netted radar are verified by simulation experiments.
