Array calibration technique for a coherent MIMO radar
conference paper
In this paper we present a technique to estimate the calibration coefficients of a coherent Multiple-Input Multiple-Output (MIMO) array radar built on a printed circuit board (PCB). Due to the integrated structure and the MIMO nature of the system, a direct measurement of each antenna element behavior cannot be performed. The proposed method is based on the evaluation of the calibration parameters from the signal reflected by dominant targets, located at different range bins, and it does not require the a priori knowledge of their angular positions. Experimental validation of the presented technique has been done and the related results are illustrated. © 2012 IEEE.
