  The integrated radar and communication system is promising in the next
generation wireless communication networks. However, its performance is
confined by the limited energy. In order to overcome it, a wireless powered
integrated radar and communication system is proposed. An energy minimization
problem is formulated subject to constraints on the radar and communication
performances. The energy beamforming and radar-communication waveform are
jointly optimized to minimize the consumption energy. The challenging
non-convex problem is solved by using semidefinite relaxation and auxiliary
variable methods. It is proved that the optimal solution can be obtained.
Simulation results demonstrate that our proposed optimal design outperforms the
benchmark scheme.
