Application of iterative algorithm in target simulator channel calibration

The influence of channels' amplitude and phase errors on target position precision was simulated and analyzed based on the principle of binary array orientation. We calculated ratios of channels' electric field intensity corresponding to different target positions. An iterative algorithm which used in channel calibration of four-element-array target simulator is designed. Experimental results prove that it can satisfy the requirements of high accuracy, and is applicable to a lot of target simulation systems.
