In this work, we consider the joint design of a surveillance radar and a multiple-input multiple-output communication system sharing the same bandwidth. In this framework, we maximize the energy efficiency at the communication system (i.e., the amount of information reliably delivered per unit of consumed energy) under a constraint on the minimum signal-to-disturbance ratio for each inspected range-azimuth resolution cell of the radar. The transmit powers of both systems, the space-time linear communication codebook, and the radar receive filters are the degrees of freedom for joint system optimization. The block coordinate ascent method is used to find an approximate solution to this optimization problem, and a numerical example is provided to show the merits of the proposed design strategy.

Abstract

In this work, we consider the joint design of a surveillance radar and a multiple-input multiple-output communication system sharing the same bandwidth. In this framework, we maximize the energy efficiency at the communication system (i.e., the amount of information reliably delivered per unit of consumed energy) under a constraint on the minimum signal-to-disturbance ratio for each inspected range-azimuth resolution cell of the radar. The transmit powers of both systems, the space-time linear communication codebook, and the radar receive filters are the degrees of freedom for joint system optimization. The block coordinate ascent method is used to find an approximate solution to this optimization problem, and a numerical example is provided to show the merits of the proposed design strategy.
