However, to fully exploit their potential, such systems require excellent time and phase synchronization among the central unit and the radar heads. Only recently, thanks to microwave photonics (MWP) techniques, it has been possible to develop the first coherent MIMO radar demonstrators. In this paper, a simulation tool in MATLAB programming language is proposed to model coherent MIMO radars based on MWP techniques in maritime surveillance applications. Moreover, a novel approach for estimating the radar cross section of extended maritime targets is presented. The system performance in co-located and distributed MIMO configuration, as well as in single- and multi-band operations, is evaluated by means of relevant key performance indicators (KPIs). Simulations are carried out in two close-to-reality scenarios. In the...

In this work, the chip has been packaged and engineered for its use in a complete radar system capable of operating up to the X band. The electronic RF frontend and the digital baseband equipment have been developed in order to guarantee performance aligned with the state of the art of conventional radars. A first indoor field trial has been carried out in X band. Range/Velocity acquisitions allow to confirm the radar system effectiveness, posing the base for the next step: the multiband field trial and coherent data fusion.
