摘要
低电平扫描场(LLSF)测试是通用飞机高强辐射场(HIRF)防护设计验证和安全性评估的重要内容。针对通用飞机的HIRF防护需求,通过研究HIRF到飞机的耦合机理,提出了一种基于LabVIEW的低电平扫描场测试系统设计方法,并详细地阐述了系统的硬件组成和软件开发流程。该测试系统具有操作简单、自动化程度高等特点,可实现飞机待测舱室内场强的多通道快速测试。以某型通用飞机为对象开展飞机级LLSF测试,通过试验获取了飞机舱室在不同照射角度下的衰减特性,完成了测试系统的应用验证。
Low Level Swept Field(LLSF) testing is an important part of High Intensity Radiated Field(HIRF) protection design verification and safety assessment for general aircraft. A new LLSF test system based on LabVIEW is proposed in order to meet the HIRF protection requirements of general aircraft,according to study the coupling mechanism of HIRF to aircraft. The composition and development process are described in detail. The system is simple to operate and highly automated,which can realize the multichannel test of the field strength inside the cabin. The attenuation characteristics of the cabin under different angles are obtained and the test system is verified by an aircraft-level LLSF test on a certain general aircraft.
