Abstract:

As the demand for high-integration and multi-function combat platforms increases, the detection and communication integration technology of phased array radar becomes a very popular field of research at the moment. This paper focuses on the engineering implementation of detection and communication integration for phased array radar, and designs an optimized mechanism, which uses mainly time division multiplexing, supplemented by frequency and space division multiplexing. This paper proposes a resource scheduling algorithm based on asynchronous dual time pointers for simultaneous multitasks, and implements the transmit/receive (T/R) module front end of detection and communication integration. The experimental results show that the proposed design could meet the requirements of detection and communication integration for phased array radar communication, which could provide a feasible engineering implementation method.

Key words: phased array radar, transmit/receive (T/R) module, detection and communication integration, time division multiplexing, resource scheduling algorithm
