摘要
复杂目标的激光雷达散射截面(LRCS)一直以来是激光探测和隐身中很重要的一个参数。对于LRCS计算的理论方法已经比较成熟,但是在将目标建模、目标表面材料涂覆、且标整体LRCS计算相结合的一体化设计方面,还存在一些有待解决的问题。针对该问题,介绍了一种基于Unigraphics造型软件,结合图形电磁计算(GRECO)以及双向反射分布函数(BRDF)模型的复杂目标(涂覆)LRCS计算软件的一体化开发方法。计算实例表明,使用这种方法,程序的一体化设计效果良好,而且具有较高的计算精度和准确性。
The laser radar cross section (LRCS) of complex target is a very important parameter in laser acquisition and stealth all the time. The theoretical method of calculation of LRCS is comparatively mature,but in the overall combination design of target modeling, target surface coating materials and LRCS calculation integration, there are still some problems remaining to be solved.Aiming at this problem, we introduce anapplication integration developing method of complex target's (coating material) calculation of LRCS based on Unigraphics modelling software, model of bidirectional reflectance distribution function (BRDF) and graphical electromagnetic computing (GRECO). The program's application integration design is effective, proved by calculation examples based on this method, besides, this method has high precision and accuracy in computing.
