摘　　要：针对近日媒体广泛报道的"美国测试超大范围GPS干扰技术"事件,论文根据禁航通告中公布的受影响范围,通过对压制干扰的干扰容限、干扰发射功率与作用距离的深入分析,认为美军在此次实验使用千瓦量级的干扰发射功率即可完成对半径几百公里范围内的GPS接收机完成干扰,其根本原因在于GPS信号太过微弱,这也进一步说明了GPS系统的脆弱性。同时,本文认为当接收机采取抗干扰措施后,大范围干扰GPS接收机的实现代价将非常巨大。According to the incident that US military tests massive GPS jamming weapon over California,this paper makes feasibility analysis from the perspective of jamming tolerance and the relationship between the transmit power and the working distance.Simulation results show that the jamming source with KW power can make the GPS receivers jammed within the radius of several kilo meters.In this paper,we conclude the feasibility of the super-large scale jamming to the vulnerability of GPS signal.Simultaneously,we also consider that the price of implementing super-large scale jamming will be super expensive on the condition of the receivers taking anti-jamming measure accordingly.
