Research on Feeder Phase Calibration for Vehicle andShipborne Tracking and Control Equipment

摘要:

针对车载和船载测控设备在校相过程中面临的远场条件限制问题,提出了一种基于馈源的校相新思路。通过分析校相与馈源和天线的关系,设计并实施了天线和馈源的远近场实验,验证了两种馈源校相方法：馈源位置比对法和馈源校相修正法。数据分析表明,采用馈源校相方法能够实现简单、快速且稳定的校相,有效解决了车载和船载测控设备在校相上遇到的问题。

Abstract:

Addressing the far-field condition limitations encountered by vehicle and shipborne tracking and control equipment during the phase calibration process. A novel feeder-based phase calibration approach is proposed. By analyzing the fundamental relationship between phase calibration, feeders, and antennas, experiments for both far-field and near-field conditions of antennas and feeders were designed and conducted, validating two feeder phase calibration methods: the Feeder Position Comparison Method and the Feeder Phase Correction Method. Data analysis results indicate that the use of feeder phase calibration methods can achieve simple, rapid, and stable phase calibration, effectively resolving the issues encountered by vehicle and shipborne tracking and control equipment in phase calibration.
