Phased Array Radar, High-speed Optical Transmission Control System Design

This thesis focuses on the high speed fiber data bus technology according to amajor program, namely Wideband Optical Phased Array Radar. High speed data bustechnology is the working house and core of the next generation PAR, and will play a keyrole in realizing beam controlling system integration, improving fighter's performance andsurvivability.At the beginning, the thesis reviews the history and current state of the developmentof beam controlling system and data bus. It states that the next generation PAR data busmust support large bandwidth capabilities, optical fibre as transmission media, distributedcontrol mechanism and powerful fault tolerance performance. Then, the thesis not onlydiscusses the main data bus technologies in the past two decades, but also comparestwo of the promising data bus which are being considered for the next-generationPAR: linear token passing bus (LTPB)and FDDI token passing ring. With the comparisonresearch of the both data bus in many aspects and detailed analysis of the FDDI protocol,the thesis draws a definite conclusion that beyond bandwidth, latency and flexibility,some of FDDI's salient characteristics making it well suited to PAR applications.Based on this, FDDI is clearly the emerging data bus technology of choice for the nextgeneration PAR.The design and implementation of the intelligent FDDI adapter is focuses on. Firstly,the specification of FDDI is analyzed in detail. Then, it describes the adapter's schemeand its circuits and software. Finally, the thesis discusses strategies adopted to optimizeFDDI performance from the view of the PAR environment.
