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.
