Improved joint radar-radio (RadCom) transceiver for future intelligent transportation platforms and highly mobile high-speed communication systems

A multifunctional transceiver for integrated radar sensing and radio communication (or simply termed RadCom) systems is developed in the time domain. It is a robust alternative of the previous architecture for a smart system that operates jointly as radar or radio in consecutive time slots. Following a system design approach, a low-frequency prototype of the proposed transceiver is realized and its performance is evaluated. Within the radar mode, the added ability of target detection as well as improved range resolution against the previously demonstrated version makes the system suitable for driving assistance applications. Within the radio mode, it has proved a great capability of communication at a data rate of 25Mbps.
