摘　　要：现代战争中,争夺战场主动权甚至是制胜权的核心就是争夺电磁频谱的主动权。为了保证尽可能全面、准确和及时地获取信息,作战平台和侦察平台的结合是必然的发展要求,机载多平台时差无源定位技术将是今后战争中所依赖的关键技术之一。围绕机载多平台时差定位技术,对其定位原理进行了阐述,对其定位误差进行了推导,并对不同构型情况下的定位精度进行了仿真分析。In modern war, the core of fighting for the initiative and even winning on the battlefield is to fight for the initiative of electromagnetic spectrum. In order to ensure to fetch information as comprehensive, accurate and timely as possible, the combination of combat platform and reconnais sance platform is an inevitable development requirement,and airborne multi platform time differ ence passive location technology will be one of the key technologies depended on in the future war. This paper,focusing on the airborne multi platform time difference localization technology, describes the location principle, derives the location error, simulates and analyzes the location accu racy under different configurations.
