摘　　要：TD-LTE系统是我国自主知识产权的第三代移动通信技术TD-SCDMA的演进系统。根据国家相关政策,2300-2400MHz频段可能成为TD-LTE系统首选工作频段,但是,我国在2300-2400MHz频段已经部署了一定规模的军用脉冲式雷达。本文针对在2300MHz-2400MHz频段上,TD-LTE系统和雷达可能发生的相互干扰问题,进行了干扰分析的确定性计算,并且仿真TD-LTE系统和雷达的相互干扰结果,分析了两个系统在互不干扰条件下部署的物理间隔,最后分析了TD-LTE系统和雷达干扰可能的主要原因。TD-LTE system is an evaluation system based on third generation mobile communication technology （ TD-SCDMA） with state independent intelligence property rights. On basis of state relative policy, frequency band （2300-1400MHz） may become priority frequency band selected by TD-LTE system. However, the military pulsed radars have been deployed in some scale in this frequency band （2300-2400MHz） in our country. Aiming at mutu-al jamming problems may occur between TD-LTE systems and radars in frequency band （2300-2400MHz）, the de-terministic calculation of jamming analysis is performed, the mutual jamming result of TD-LTE system and radar is simulated, the physical interval of two systems deployed in condition of not being jammed is analyzed, and finally, the major possible cause of TD-LTE system and radar jamming is analyzed.
