Design of Beamforming for Full-duplex Integrated Radar and Secure Communication System
摘要
Abstract
An artificial noise-assisted beamforming method is proposed to ensure communication security and reduce the energy con-sumption of the full-duplex joint radar-communication system.Considering that the location of the eavesdropper is unknown,under the constraints of the secure communication requirement and the received signal-to-noise ratio from the target,the transmitted power is minimized through optimizing the transmit beamforming,receive beamforming and the added artificial noise.This optimization problem is analyzed by semidefinite relaxation and successive convex approximation,then a closed-form solution for the receive beam-forming vectors of the radar and uplink communication are derived.And then,an iterative algorithm is proposed to obtain the optimal transmit beamforming matrix and artificial noise covariance matrix.Compared to the conventional half-duplex system,simulation re-sults show that the system achieves full-duplex secure communication with a limited increased power consumption.Besides,compared to the commonly used block coordinate descent method,the proposed algorithm achieves lower power consumption.关键词
