Original Paper


In this paper, we apply the Newton-type method for the optimization of cost functions for spectrum estimation-based bistatic DOD (direction of departure)/DOA (direction of arrival) estimation algorithm of the bistatic conventional beamforming and the bistatic capon beamforming algorithm in the bistatic MIMO radar system. Explicit expressions of the first derivatives and the second derivatives of the cost functions are presented. The Newton-type search for simultaneous update of the DOD/DOA based on the gradient and the Hessian of the cost function is also presented. The performance improvement in terms of estimation accuracy is demonstrated using the Monte–Carlo simulations.
