= Joint communication-radar system - already here = A joint communication and radar sensing system (JCRS system) is radio frequency system that can be used simultaneously as a radar and a wireless communications system. The same signal is used to detect a target and its position, and communicate information. JCRS systems is an active area of research. It would allow more efficient spectrum management and less spectrum congestion, sharing the same physical radio antenna.
