Direct positioning of stationary targets using MIMO radar

MIMO radar is a new concept that has recently been proposed as an extension to the multi-static radar systems. We apply the direct position determination (DPD) approach to MIMO radar and obtain maximum likelihood algorithms for a location estimation of a stationary target. It is shown that under low signal to noise ratio DPD improves the estimation accuracy with respect to the traditional location methods.
