摘要
提出了一种相控阵雷达横滚角标校方法,利用相控阵雷达横滚角与目标俯仰角测量误差之间的近似线性关系,结合雷达自带的角度测量误差标定手段,快速地计算得到雷达的横滚角,进而大幅提高相控阵雷达的角度测量精度。实验证明,使用该方法计算得到的横滚角与使用激光测量仪器测得的横滚角结果精度相当,完全能够满足高精度测量雷达的需求。
This paper presents a roll angle calibration method for phased-array radar.Based on the built-in elevation calibration methods of phased-array radar,the proposed method utilizes the approximately linear relationship between the roll angle and the target’s elevation measurement error to calculate the roll angle.Experiments confirm that the roll angle calculated by this method has nearly the same accuracy as that of the method using laser measurement instruments.With the proposed method,the angle measurement accuracy of phased-array radar can be greatly improved.
