Antenna array-based joint radar-communication (JRC) system employs the beamforming strategy to steer the transmit signals in different directions such that different beamforming weight vectors are exploited which perform the corresponding radar-communication objectives. Such functionality has been provi-...
Radar and communication systems are hosted on the same platform in many civilian and military applications. Traditionally, radar and communication systems are separately designed, which increases the system size, cost, and power consumption, and decrease

To increase the communication symbol rate, more recent DFRC designs tend to use MIMO radars due to their rich Degree of Freedom (DoF) in waveform design. For example, the beam patterns of a MIMO radar are optimized to take advantage of sidelobes to conduct communication modulations, e.g. ...

Beamforming techniques are proposed for a joint multi-input-multi-output(MIMO) radar-communication (RadCom) system, where a single device acts both asa radar and a communication base station (BS) by simultaneously communicatingwith downlink users and detecting radar targets. Two operational options ...
problems. The first category considers that the targets may appear in a certain area, and then designs the transmit beamforming vector to focus the transmit energy into that area, thereby the potential targets are more likely to be discovered by the radar [15]. To implement this, some works...
The dual-functional radar and communication (DFRC) technique constitutes a promising next-generation wireless solution, due to its benefits in terms of power consumption, physical hardware, and spectrum exploitation. In this paper, we propose sophisticated beamforming designs for multi-user DFRC systems...
