Abstract: Converged communication and radar sensing systems have attained increasing attention in recent years. The development of converged radar-data systems is reviewed, with a special focus on millimeter/terahertz (THz) systems as a promising trend. Firstly, we present historical development and convergence technology concept for communication-radar systems, and highlight some emerging technologies in this area. We then provide an updated and comprehensive survey of several converged systems operating in different microwave and millimeter frequency bands, by providing some selective typical communication and radar sensing systems. In this part, we also summarize and compare the system performance in terms of maximum range/range resolution for radar mode and bit error rate (BER) /wireless distance for communication mode. In the last section, the convergence of millimeter/THz communication-radar system is concluded by analyzing the prospect of millimeter-wave/THz technologies in providing ultrafast data rates and high resolution for our smart future.
