由于采用单一接收天线的卫星导航接收终端抗干扰能力极弱,提出了一种自适应天线方案,包括多阵元微带天线阵列和功率倒置算法。以北斗二代B3频点为例,设计了四阵元微带天线阵列、射频前端、基带处理单元和空域功率倒置算法。仿真和实物测试结果表明,所提出的抗干扰方法性能优良,在同时存在3个宽带干扰,且干信比大于70d B时,导航终端仍然能够正常定位。
Due to the extremely weak anti-jamming capability of the satellite receiving receiving terminal with a single receiving antenna, an adaptive antenna solution is proposed, which includes a multi-element microstrip antenna array and a power inversion algorithm. Taking Beidou second generation B3 frequency point as an example, a four-element microstrip antenna array, a radio frequency front-end, a baseband processing unit and an airspace power inversion algorithm are designed. Simulation and in-real test results show that the proposed anti-jamming method has excellent performance. When there are three wideband interferences at the same time and the SINR is greater than 70d B, the navigation terminal can still locate normally.
