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。
Complex target laser radar cross section (LRCS) has long been an important parameter in laser detection and stealth. The theoretical methods for LRCS calculation have been relatively mature, but there are still some unresolved problems in the integrated design of target modeling, coating of target surface material, and standard LRCS calculation. In view of this problem, an integrated development method of complex target (coated) LRCS calculation software based on Unigraphics modeling software combined with Graphical Electromagnetic Computing (GRECO) and Bidirectional Reflection Distribution Function (BRDF) model is introduced. The calculation example shows that the integrated design of the program works well with this method, and has higher accuracy and accuracy.
