At Arizona State University, Center for Wireless Information Systems and Computational Architectures (WISCA) researchers develop theories, system concepts, and experiments for RF convergence of simultaneous sensing and communications. For the sensing aspect, this discussion focuses on radar, though the approach has broader applicability technically. The discussion introduces range of commercial and noncommercial applications. Observed commercial applications will likely soon outpace military interest. Commercial applications include employment of millimeter wave RF systems that perform communications and short range radar. Potential radar applications include hand gesture identification and health and fitness analysis.
The discussion identifies a range of system concepts and sensing and communications topologies, presents simulated and experimental examples, and provides an overview of the current state of RF convergences research.

The discussion uses an experimental example to demonstrate simultaneous reception of communications waveform and traditional chirp radar waveform. WISCA’s MATLAB in the loop software-defined radio system employs GPS-synchronized radios to operate at a scheduled low duty cycle to enable over-the-air experiments, while allowing complicated processing with interpreted MATLAB. With this approach, researchers:
