Design of scalable beam steering system of phased array radar

The development of phased array radar puts ever-increasing demand on its beam steering system. Especially, for a large-scaled two-dimensional phase controlled radar, its beam steering system should provide a rapid and flexible beam steering control in order to realize a real-time control of the radar in target search and tracking. The paper presents a beam steering system with scalable basic modules made up of an integrated transceiver and receiver (T/R) modules and embedded controllers. By use of this beam steering system, a real-time beam steering control for all the elements in the antenna array can be realized.
