摘要：

This paper introduces a fast and efficient algorithm to calculate the radar cross section of complex targets using shooting and bouncing rays. The method combines a multiresolution grid division algorithm, with an algorithm that divides space using an octree structure. Applying the two division algorithms simultaneously, accelerates computation speed in ray tracing without reducing accuracy. Numerical results show the accuracy and efficiency of the proposed method.
