Multidimensional Scaling Analysis for Target Localization From Bistatic Range Measurements in Distributed MIMO Radars

The multidimensional scaling (MDS) analysis is exploited in this paper to localize the target using bistatic range (BR) measurements in multiple-input multiple-output (MIMO) radar systems. Two methods are proposed, which are termed distributed MDS and joint MDS methods, respectively. In the proposed methods, the scalar product matrix in classic MDS framework is formulated using BR measurements. By minimizing the cost function composed of multiple scalar product matrices, a closed-form solution for target location is presented. Simulation results demonstrate the effectiveness of the proposed methods.
