Simultaneous target detection and multi-user communications enabled by joint beamforming

Simultaneous target detection and multi-user communications enabled by joint beamforming
Simultaneous target detection and multi-user communications enabled by joint beamforming

In this paper, we propose several joint beamforming designs for the multi-input-multi-output (MIMO) dual-functional radar-communication system. We firstly split the antennas into two groups, one for radar and the other for communication. With this separated deployment, the radar signal is designed to fall into the null-space of the downlink communication channel. The communication beamformer is optimized such that the obtained beampattern matches the radar's beampattern while satisfying the performance requirements of the downlink users. We further consider a second operational option, where all the antennas transmit a joint waveform that is shared by both radar and communications, and formulate an appropriate beampattern while guaranteeing the downlink cellular transmission. Numerical results show that both methods are able to realize the simultaneous radar detection and wireless information transfer.

Abstract

In this paper, we propose several joint beamforming designs for the multi-input-multi-output (MIMO) dual-functional radar-communication system. We firstly split the antennas into two groups, one for radar and the other for communication. With this separated deployment, the radar signal is designed to fall into the null-space of the downlink communication channel. The communication beamformer is optimized such that the obtained beampattern matches the radar's beampattern while satisfying the performance requirements of the downlink users. We further consider a second operational option, where all the antennas transmit a joint waveform that is shared by both radar and communications, and formulate an appropriate beampattern while guaranteeing the downlink cellular transmission. Numerical results show that both methods are able to realize the simultaneous radar detection and wireless information transfer.
