摘　　要：基于移动平台的无线电辐射源测向技术广泛应用于飞机、飞艇等平台,由于测量过程中移动平台的位置、姿态不断变化,与基于静止平台的测向系统相比,测向误差源数量增多,测向精度变差。本文针对目前广泛应用的辐射源干涉测向技术,通过模拟仿真计算,进行不同误差源特性分析,对基于移动平台的辐射源干涉测向精度设计提供了技术依据。There are additional error sources in radiation direction finding system based on moving platform, compared with which based on unmoving platform, so we would get the fading precision of radiation direction finding. The additional error is caused by the changing of platform position and platform attitude. In this paper, it will be analyzed about the characteristics of different error sources. The conclusion could used as the foundation for precision design of radiation direction finding with interferormeter based on moving platform.
