Abstract: Anti-jamming compatible type satellite navigation receiver can use the combination of satellite positioning systems to perform high-precision positioning, and also has an excellent anti-interference performance by the application of adaptive null steering antenna. The hardware circuit of the system is introduced, and the hardware platform is adopted by the power inversion algorithm for interference suppression. Simulation results show that the adaptive null steering antenna can effectively improve the SNR of the received signal, and can expand the application range of compatible type satellite navigation receiver.
Key words: BD/GPS/GLONASS compatible receiver, adaptive null steering antenna, power inversion, satellite navigating and positioning
摘要: 抗干扰兼容型卫星导航接收机既可以使用组合卫星定位系统进行高精度定位,又具有优良的抗干扰性能。其抗干扰性能通过自适应调零天线实现,介绍了系统硬件电路实现,并在相应硬件平台上,采用功率反演算法进行干扰抑制。仿真测试结果表明,自适应调零天线有效地提高了接收信号的信噪比,提高了兼容型卫星导航接收机的应用范围。
