High Frequency Surface Wave Radar Antenna Array Calibration Using Automatic Identification System Data

摘要: 该文提出了一种利用自动识别系统(AIS)信息进行高频地波雷达天线阵校正的方法。该方法使用高信噪比的舰船目标回波信号和目标的AIS信息解算天线阵的相位误差和增益误差。该方法的校正精度高于使用非合作目标回波的盲校正算法，同时无需部署专用信标机，并可以实现随时校正。使用高频地波雷达实测数据以及相应的AIS数据对新方法的性能进行了检验，其结果证明了新方法的优势。

Abstract: A high frequency surface wave radar antenna array calibration method using Automatic Identification System (AIS) data is presented. The new method uses ship target echoes with high SNR and their AIS data to find the phase and gain errors of the antenna array. The new method can achieve better array calibration precision comparing to existing blind array calibration methods, requires no dedicate beacons, and can do the calibration at any time. Real measured high frequency surface wave radar data and corresponding AIS data are used to test the new method, and the result proves the advantage of the new method. -
