摘要
首先在研究GPS欺骗干扰特性的基础上,寻找转发欺骗干扰和自主生成式欺骗干扰的共同特点;其次,利用多阵元接收天线的DBF技术和RAIM算法,提出一种针对GPS欺骗干扰的抗干扰方法;最后,通过试验验证该方法的可行性。试验证明该抗GPS欺骗干扰的方法针对性强,对抗欺骗干扰效果较好,可应用于民用和军用GPS接收机抗干扰当中。
A method of anti-spoofing jamming is proposed. Firstly, the characteristics of spoofing jamming are studied based on the study of GPS deception jamming characteristics. Secondly,u- sing DBF and RAIM algorithm of multi-element receiving antenna, anti-spoofing jamming meth- od is proposed. Finally, the feasibility of the method is verified by the experiment. The method could be used in the anti-jamming of civil and military GPS receivers.
