Abstract

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 phase of the array antenna element, the synthesize wave spreading to the antenna surface created by array antenna is the quasi plane wave which can satisfy the X band antenna far-field calibration condition. Integrated using optimization theory and genetic algorithm,the weight values of array antenna element amplitude and phase are optimized, thus the synthesize wave can be more closer to the quasi plane wave. The quasi plane wave produced by this method can satisfy the far-field calibration condition in both computer simulation and outfield experiments.
