机载广域侦察监视(Wide Area Airborne Surveillance,WAAS)系统因其具有良好的隐蔽性和动态实时性、高分辨率及宽覆盖范围等特性,已成情报侦察监视(ISR)的重要手段和世界各国重点发展的航空装备.本文对当前机载广域侦察监视系统装备发展情况进行了介绍,结合国外典型广域侦察监视系统技术,对一种基于稳定平台摆扫步进凝视(Step-Stare)成像的广域侦察监视系统进行了关键技术设计论证,为机载广域侦察监视系统研制与应用提供参考.%Wide area airborne surveillance (WAAS) systems have emerged a sprimary tools for intelligence, surveillance, and reconnaissance, and are currently the focus of development all over the world because of their qualities such as superior concealment, real time dynamics, high resolution, and large area coverage performance. The current development of WAAS systems is discussed in this paper, along with a description of the typical technology used for WAAS systems abroad, the key technology design, as well as the demonstration of a WAAS system based on stable platform sweeping stepped imaging. Our studies provide an excellent reference for the development and application of WAAS systems.
