Research on the Calibration Algorithm for Circular Array in the Presence of Amplitude and Phase Error

Abstract:

The calibration algorithm for circular array in the presence of amplitude and phase error is researched deep exploiting the assistant sensors. In order to calibrate the amplitude and phase error for the circular array, in this paper, two setting methods of assitant elements are presented, i.e., assitant elements are setted on the coordinate axis and on circle. Simulation experiments results show that the two proposed setting methods are effective in the presence of amplitude and phase error for circular array, and has low computational burden and high estimation precision of angle and amplitude and phase error.
