Abstract

Integration of radar and communication (Radcom) is one of the important research areas for multi-functional integrated radio frequency systems. Most attention has been drawn to the Radcom system based on signal-sharing, due to its high integration degree. Firstly, the study discusses the application of complementary code to the integration of Radcom and constructs a multi-carrier DC-code-division multiple access system to integrate Radcom. Secondly, in allusion to the integrated system, the study presents the algorithm of timing and frequency synchronisation. The algorithm adopts timing synchronisation of energy detection and carrier synchronisation of temporal correlation and frequency complementary property. Theoretical analysis and simulated results show that the algorithm has excellent performance and satisfies the requirement of synchronisation for burst and instantaneous communication.
