一种小尺寸极化阵列及其高精度定位波束形成
A Small Polarization Sensitive Array and Its Beamforming for High Accuracy Positioning
摘要
Abstract
A polarization sensitive antenna array composed of dipoles is proposed for receiving Global Navi-gation 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 an-tenna array,the proposed array's antenna component is simpler and has smaller footprints. Through develo-ping the polarization array data model,the polarization and beamforming phase effects are analyzed. The im-pact 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.关键词
