Research on Application of Array Antenna in United X Band System Calibration
2016
Proceedings of the 2016 Joint International Information Technology, Mechanical and Electronic Engineering
unpublished
The distance between the existing calibration tower of the survey ship base and survey ship is only 980 meters which can't satisfy the United X Band system antenna far-field calibration condition. To solve the problem,a method using array antenna to synthesize quasi plane wave is presented to implement the far field calibration under the condition of the near distance. Sixteen horns were used to build the 4 by 4 array antenna equipment on calibration tower. By controlling the amplitude and
