摘　　要：目前北斗/GPS双模接收系统的抗干扰研究还比较少,主要是针对GPS的抗干扰研究。北斗和GPS接收机易被干扰,为了改善强干扰环境下接收机的性能,研究不同阵列、不同算法对接收机抗干扰性能的影响,在GPS的抗干扰研究的基础上设计并实现了一套北斗和GPS双模接收系统的抗干扰平台。实验结果表明,该系统能使北斗和GPS双模接收机在-30dBm强干扰的环境下搜到6颗北斗导航卫星和5颗GPS导航卫星,并正常定位,说明该系统能达到干扰抑制的目的。该系统也可推广至多种卫星导航接收机的抗干扰平台。BeiDou and GPS receivers are susceptible to interference.In order to improve the performance of the receiver under strong jamming environment,the effects of different arrays and different algorithms on the anti-jamming performance of the receiver were studied.An anti-jamming platform for BeiDou and GPS dual-mode receiving system was designed and implemented on the basis of GPS anti-interference research.The experimental results showthat by this system,the BeiDou and GPS dual-mode receivers can search up to 6 BeiDou navigation satellites and 5 GPS navigation satellites,and locate under the environment of-30 dBm strong interference.The system can also be extended to a variety of satellite navigation receivers anti-jamming platform.
