Dual Redundancy Design Method for Data Processing Computer in Phased-array Radar

The features of dual redundancy for data processing computer in the phased array radar are described briefly ,and the dual redundancy system is designed with higher reliability. The dual redundancy design for data processing computer is realized with the aid of software and hardware, and the block diagrams of hardware and software for fault detection and system switching are given, then reconstructing strategy and its process of dual tolerance system are analyzed. Finally, applications of dual redundancy design in the control system of the phased array radar are proposed.
