Design of a Phased Array Radar Wave Control System for Highly Integrated Active Array Surface
For the requirements such as high integration,multi-channel and low-cost of antenna sub-arrays design in large-scale phased array radar,this paper designs a wave control system.This wave control system adopts a hierarchical architecture approach,and achieves the wave control of large-scale phased array radar systems by individually controlling the parameters of thousands of antenna unit transmission and reception channels through a single wave control unit.In the design,func-tions of digital wave control and RF power division are integrated to the board of wave control u-nit,and a single K7 series field progammable gate array(FPGA)is used for data decoding,distri-bution and timing control.By using a three-dimensional stacked assembly method,the mode of su-per subminiature push(SSMP)blind matching interconnection and small hybrid elastic intercon-nection is seleted,and optical fibers are used to receive and transmit control parameters,which im-proves the system integration of the active array,and optimizes the volume and weight of the ar-ray.
