基于TDOA的通信卫星运动干扰源跟踪技术研究

Research of Communication Satellite Moving Interferenee Tracking Based on TDOA

近年来,针对通信卫星的有意干扰事件时有发生,其干扰平台由传统的地面固定平台向地面、海面、空中运动平台发展,给干扰源监测工作带来新的挑战。在此背景下,提出基于TDOA的三星定位体制并结合EKF滤波算法实现对运动干扰源的定位跟踪方法。通过数据仿真进行验证,表明该方法对地球表面运动干扰源目标定位跟踪精度可达公里级,可实现对此类运动干扰源的快速精准监测。

Recent years,incidents of deliberate interference with communication satellite occur from time to time,and the interference platform develops from ground fixed platform to ground,sea,and air movement platfrom.This brings new challenges to the monitoring of interference.In this context,this paper proposes a three-satellite positioning system base on TDOA combined with EKF filter algorithm to achieve tracking of moving interference.The simulation data is used to test and the results show that the accuracy of the method is on the order of kilometers,which can achieve rapid and accurate monitoring of such moving interference.
