摘要
为了帮助指挥员在电子对抗中准确判断态势,研究三维雷达探测范围构建与优化实现技术。基于Open Scene Graph(OSG)三维图形引擎,结合雷达探测范围二维包络线和雷达天线垂直方向图函数,实现了三维雷达探测范围的通用计算方法。针对雷达数据量大、数据实时更新的特点,分2个阶段进行优化:降低算法复杂度,优化计算方法;使用OSG的多线程技术,对计算绘制过程进行并行处理。通过试验与分析,验证了本文方法的高效性。
To help the commander determine situation accurately in electronic countermeasure,this paper researches the construction and optimization implementation technology of 3 D radar detection range. Based on Open Scene Graph(OSG) 3 D graphics engine,and combining radar detection 2 D area with vertical detecting distance calculating method,this paper achieves the general method for calculating 3 D radar detection range. In the light of the large volume of radar data and real-time data updating,it is optimized in two stages: reducing the algorithm complexity and optimizing calculation method; using OSG multithreading technology to conduct parallel processing for the calculating drawing process. Through the test and analysis,the efficiency of multithread method is proved.
