Optimal Geometry Analysis for Elliptic Localization in Multistatic Radars With two Transmitters

The relative transmitter-target-receiver geometry plays an important role in the performance of elliptic localization. In this article, we analyze the optimal geometry in multistatic radar systems, consisting of two transmitters and multiple receivers, based on the D-optimality criterion, i.e., minimizing determinant of the associated Cramer-Rao Bound matrix. First, the special case of single receiver is considered, and then, an extension to the optimal placement for the cases with even number of receivers and a near-optimal placement for the cases with odd ones are proposed. Numerical results are given to confirm the theoretical analysis.
