一种预估有行波散射特征目标的RCS的新方法

RCS Prediction Based on The Hybrid Method of GRECO & Travelling Wave Theory

在图形电磁计算方法的基础上补充行波散射贡献 ,对高频区有行波散射特征目标的RCS的预估开展了研究 .从而在保留了图形电磁计算方法快速预估目标镜面散射的同时 ,以行波计算提高有行波散射特征目标的RCS的预估精度 。

Graphical Electromagnetic Computing (GRECO) is recognized as one of the most important method of RCS computation for the high-frequency region.But as the effect of traveling wave was not considered in GRECO,the agreement between GRECO and our measurement is not favorable.The effect should be analyzed by other methods.By the hybrid method of GRECO and traveling wave theory satisfactory results are obtained.
