Abstract：With the development of mobile communication technology，the bandwidth demand of International Mobile Telecommunications （IMT） expands rapidly.For this reason，research has been carried out on sharing the same frequency bands with space radio services.This article takes earth exploration satelite service in the7/8 GHz frequency band as the point of penetration to explore the calculation method for frequency interference between satelite networksand IMT systems，in order to provide reference for frequencycompatibilitybetween IMTsystems andsatellite networksinotherfrequencybands.

Keywords：satellite networks;IMT systems;interference analysis

隨著公眾移動通信系統(tǒng)（IMT）對帶寬需求的不斷增加，為其新增頻率劃分一直是近幾屆國際電信聯(lián)盟（ITU）世界無線電大會（WRC）的熱點議題，并開始研究與空間業(yè)務(wù)頻率共用的可能。（剩余4902字）
