Abstract :
An algorithm for mutual coupling calibration in multi-carrier bi/multi-static radar is presented. Based both on the mathematical model of the mutual coupling and subspace principle, the algorithm using direct wave signal is proposed for estimating mutual coupling matrix of uniform linear array. The direction of arrival (DOA) estimation with mutual coupling is also discussed. The computer simulation results show the validity of the new calibration algorithm
