摘要

摘要:
低电平扫描场（LLSF）测试是飞机级高强辐射场（HIRF）效应试验的重要内容。分别建立了方形舱室内置模式搅拌叶片的仿真模型和试验系统，验证了外部LLSF照射下非封闭舱室内产生统计均匀特性电场的可行性。以方形舱室和圆柱舱室模型为对象，提出了基于遍历和递归算法的场均匀区域检验方法，获取了模式搅拌工作下的2种非封闭舱室内的有限均匀区域，为实际飞机级LLSF试验过程中接收探头的布置提供重要指导。

Abstract:
Low level swept field (LLSF) testing is an important part of aircraft-level high intensity radiated field (HIRF) effect measurements. The simulation model and experimental systems of LLSF effect for cuboid-shaped cabin with mechanical mode stirrer placed internally were established. Encouraging numerical and experimental results validated the possibility of statistical uniformity characteristic inside the non-enclosed cabin, which is illuminated by LLSF, with the help of mode stirrer. Then, the simulation models of non-closed cuboid-shaped cabin, as well as the cylindrical cabin were considered. The searching and testing method is proposed based on the traversal and recursive algorithm. The frequency-dependent regions of uniform electric field inside cabins were obtained by using the proposed valid test method. The objective is to provide an important guidance for limiting the regions of receiving probes or antennas in practical LLSF measurements.
