Paper Abstract

By fixing a glass cubic prism facing an antenna, the positional relation between the coordinates of the cubic prism and the mechanical shaft was measured in a lab for the antenna, and the positional relation between the coordinates of the cubic prism and the wave was measured in a microwave anechoic chamber. The positional relation between the antenna and the wave was used to calibrate the positional consistency between the mechanical shaft and the electronic boresight. The calibration uncertainty was calibrated by analyzing the measurement data collected in the lab and the microwave anechoic chamber. Experimental results indicated that the proposed method could be used to calibrate the positional consistency between the antenna and the electronic boresight of a radar system, and the calibration results are within the accuracy limits for radar antennas.
