基于解析积分的TDSBR算法及其在目标散射中的应用

TDSBR algorithm based on analytic integral and its application in scattering problems

在传统的时域弹跳射线(Time Domain Shooting and Bouncing Rays,TDSBR)方法的基础上,采用基于解析积分的时域物理光学(Time Domain Physical Optics,TDPO)方法计算目标的散射场.与传统弹跳射线法相比,新方法明显减少了射线管的数量,节省了计算内存,是一种分析电大尺寸目标散射问题的高效方法.最后,通过数值计算结果验证了该方法的可靠性和高效性.

Based on the traditional time domain shooting and bouncing rays （TDSBR）, the scattering field of the target is calculated by the time domain physical optics （TDPO） algorithm based on analytic in- tegral. Compared with the traditional SBR, this new method obviously reduces the number of ray tubes and saves computer memory. It is an efficient method for analyzing the scattering problem of electrically large objects. The numerical results demonstrate the reliability and efficiency of the method.
