MIMO radar signal processing for distributed phased arrays

We explore transmit signaling and receive signal processing strategies for a notional MIMO radar system consisting of widely distributed phased arrays. The assumptions are that within a phased array, there is a fixed rigid geometry and perfect phase synchronization, and there is a single look at the target. In constrast, between phased arrays there is imperfect phase synchronization and multiple views of the target. The relative advantages and disadvantages of coherent and orthogonal signaling in such a model are explored through simulation.
