摘要
结合GPS工作原理,分析了GPS干扰的类型以及相应的抗干扰技术,在此基础上提出了GPS抗干扰设计方案,并重点给出了GPS自适应调零天线射频电路的设计,实际测试和工程使用结果表明这种设计方法是切实可行的,可以在煤炭等工程中得到推广应用。
In this paper, it introduces the fundamental principle of GPS, analyzes the type of interference and corresponding anti-jamming measures, emphasizes on the technique based on adaptive antenna to realize it, and then, designs the RF units of this adaptive antenna. The actual test and engineering application results show that the design method is practical and can be used in engineering application development.
