摘要

飞行器的蒙皮在服役期间容易产生腐蚀或破损进而增大飞行器的雷达散射截面,因此需要对修复后的区域进行局部雷达散射截面(Radar Cross-Section,RCS)检测以评估修复效果。研究了一种面向工程的近远场变换算法以实现对修复区域的RCS检测,该算法基于球面波环式展开算法,并在传统近远场变换算法的基础上使用渐进式代替传统的汉克尔函数,设计了一种适用于工程应用的近远场变换算法。使用HFSS和Matlab软件对设计的算法进行了仿真验证,结果表明算法能够求得修复后局部小区域的RCS。
        Corrosions or damages often happen on the coating system of aircrafts,and the repairing process may enlarge the Radar Cross Section of aircrafts.In that case,it is necessary to conduct a partial RCS scanning on the repaired places in order to evaluate the maintenance effectiveness.This paper discusses a near-field-to-far-field transformation algorithm to realize the RCS detection of the repaired place.The conventional Hankel function is substituted by an approximation algorithm which is more suitable for application.The simulation results by HFSS and Matlab show the effectiveness of the algorithm.
