本文介绍了多接收机雷达天线阵中天线间距、方向和相位误差的自测量校准技术。利用放置在阵列的远场中的已知位置处的一组源发射器以及对每个天线处存在的相位的测量，可以确定阵列的相对天线位置和相位误差。这种技术的优点是雷达在正常工作模式下使用，在真实工作条件下提供端到端校准。利用位于格陵兰Sondre Stromfjord的流星雷达进行了自我测量校准，成功地绘制了阵列。天线位置相对接近预期位置，尽管基线从真正的基本方向旋转了大约5/spl度/。大部分相位误差是由接收机引入的。
This paper presents the self-surveying technique for calibrating the antenna spacing, orientation, and phase errors in multiple receiver radar antenna arrays. Utilizing a set of source transmitters placed at known locations in the far-field of the array and measurements of the phase present at each antenna, the array's relative antenna locations and phase errors can be determined. The advantage of this technique is that the radar is used in its normal operating mode, providing an end-to-end calibration under true operational conditions. A self-survey calibration was performed with a meteor radar located at Sondre Stromfjord, Greenland, successfully mapping the array. The antenna positions were relatively close the expected locations, although the baselines were rotated approximately 5/spl deg/ from the true cardinal directions. The majority of the phase error was introduced by the receivers.
