On System Design of Coherent Cooperative Automotive Radar Sensor Networks

The design of cooperative radar networks for automotive use cases is challenging as multiple design domains have to be considered at the same time. This includes the synchronization concept for hardware and software as well as the actual layout of the sensor geometries. We give an example on how to design a synchronization concept based on the single sensor capabilities and define a lower bound for the cooperative array sparsity. Three sensor geometries are evaluated using laboratory and real world measurements.
