摘要 提出一种偶极子天线单元构成的极化敏感阵列用于全球卫星导航信号的接收,经过阵列信号波束形成后,在抗干扰的同时保留卫星导航信号中载波相位测量值的准确性,可用于基于载波相位测量的高精度差分定位。与传统的圆极化天线阵列相比,该阵列具有阵元构造简单、尺寸小的特点。通过建立极化阵列接收信号模型,分析了天线极化和波束形成算法对卫星导航信号相位的影响,给出了相适应的相位中心稳定的数字波束形成算法。仿真验证了分析的正确性和算法的有效性。 A polarization sensitive antenna array composed of dipoles is proposed for receiving Global Navigation Satellite System(GNSS) signal. Beamforming techniques for this array are proposed and evaluated.The requirements for high accuracy positioning are also addressed. Compared with conventional GNSS antenna array,the proposed array's antenna component is simpler and has smaller footprints. Through developing the polarization array data model,the polarization and beamforming phase effects are analyzed.The impact of polarization and beamforming algorithm on carrier phase measurement and high accuracy positioning is discussed.Finally,the beamforming method suited to both anti-jamming and high accuracy positioning is proposed.Simulations show the validity of the algorithm and effectiveness of the analysis.
