Abstract: A radar controller with multiple layers architecture is the key to cooperate the large-scale distributed multistatic radars. Much attention is paid to two of the characteristics of distributed radar control system, real-time requirement and cooperating synchronously among distributed components. In this paper, a layered architecture for radar control system has been proposed. Also some key techniques, such as network system design with real-time and cooperating consideration, complex topology and redundant system implementation have been described in detail. finally give software development structure.
