为提高北斗RDSS用户终端的抗干扰能力,设计并实现了一款基于阵列信号处理的北斗抗干扰终端。终端接收部分采用数字移相波束形成,发射部分采用射频移相波束形成技术,采用微带天线实现天线阵元。终端主机采用通用功能化硬件DSP与专用功能化硬件FPGA相结合的设计方案,完成抗干扰接收和低暴露发射的综合处理。通过对工程样机的测试,与普通北斗用户终端相比,工程样机窄带干扰容限提高36 d B,宽带干扰容限提高33 d B。
Abstract:In order to improve the anti-jamming ability of BDS RDSS user terminal,a BDS anti-jamming terminal based on array signal processing is designed and implemented.Digital phase-shifting beamforming is used in the receiving part of the terminal,and the RF phase-shifting beamforming technology is used in the transmitting part,and the antenna element is realized by microstrip antenna.The terminal host adopts the design scheme of general functional hardware DSP and special functional hardware FPGA to complete the comprehensive processing of anti-interference reception and low exposure transmission. Through the test of the engineering prototype,compared with the ordinary BDS user terminal,the narrowband interference tolerance of the engineering prototype is increased by36 d B,and the broadband interference tolerance is increased by 33 d B.
