Since different types of Received in revised form targets have varying profiles, the advantages of a polarimetric radar system can fully be 3 November 2011 exploited only when the type of target is accurately estimated. However, accurate Accepted 24 November 2011 Available online 7 December 2011 estimation requires a significant amount of training data, which can be expensive. We propose a polarimetric design scheme for distributed multiple input multiple output Keywords: (MIMO) radar target detection. We formulate the selection of transmit polarizations Game theory using a game theoretic framework by examining the impact of all possible transmit Multiple input multiple output (MIMO) schemes
