摘要：

In this paper, a simple and fast calibration algorithm is proposed for an active phased antenna array measurement of the amplitude and phase of all the antenna elements. Euler's numerical method is used to simultaneously measure and calibrate the array element's electric field and array factor. Each element's phase shifts are periodically varied with a reference state through a feedback to the amplitude and phase calibration units, and their variations are calculated and analyzed for signal calibration. The method is theoretically studied using numerical simulations providing accurate performance and a very low tolerance to errors. This method provides a multiple element far field calibration technique applicable to radar, satellite, and wireless communication.
