Angle Zero Calibration Method Based on GNSS Direction-finding Principle

文章简述了采用光学标定方法进行角度零值标定的局限,提出基于GNSS双天线基线测向原理的角度零值校准方法。以基线长度可变为约束条件,进行了精度验证分析,其角度标定精度完全满足雷达等无线电装备测角精度要求,具有较高的实用价值。

In this paper, the limitation of optical calibration method to calibrate the angle zero value is described, and a method of calibrating the angle zero value based on the principle of GNSS dual antenna baseline direction-finding is proposed. Taking the length of baseline as the constraint condition, the accuracy verification analysis is carried out. The accuracy angle calibration fully meets the requirements of angle measurement accuracy of radar and other radio equipment, which has high practical value.
