摘　　要：提出了基于表面电流法的弹跳射线法,并利用对比基于接收球算法的射线追踪法和矩量法的计算结果来验证算法的计算精确性,然后采用基于表面电流法的弹跳射线法分析某型号直升飞机机载天线,对比不同位置处天线的方向图变化,分析变化原因,为实际飞机天线布局设计提供参考.This paper proposes the Shooting and Bounce Ray Method based on the surface current method,and verifies the calculation accuracy of the algorithm by comparing the calculation results of the ray tracing method based on the receiving ball algorithm and the method of moments.Then,the shooting and bouncing method based on the surface current method is used to simulate the airborne antenna of a certain type of helicopter.Comparison of the antenna pattern changes at different locations and analysis of the causes of the pattern changes can provide a reference for the actual aircraft antenna layout design.
