改进的图形电磁计算方法计算目标RCS

Improved Method of GRECO to Compute the RCS of Targets

提出了几种改进或消除图形电磁计算中有可能产生较大误差因素的方法,提高了动目标RCS计算的精度。为改善单层深度缓存的不足,引入多层深度缓存技术,考虑了多次散射对目标RCS的影响;为解决散射体过大而剖分不够精密的问题,引入分解法,提高了RCS的剖分精度;改善了边缘识别的方法,能够精确的识别棱边。

Several methods which are able to reduce the factor that may cause great error in GRECO are presented, and the accuracy of the result of RCS may be improved. The technology of the multi-Z-Buffers is presented to make up the disadvantage of the single-Z-Buffer. so the impact of multi-scattering is regarded;the method of division is presented to solve the problem that scattering object is so large that it can not divided small enough to calculate;the method of detecting edge is improved,and the edges are able to be detected correctly.
