Sparse Array Design for Dual-Function Radar-Communications System

The problem of sparse array design for dual-function radar-communications is investigated. Our goal to a which can simultaneously shape desired beam responses and serve multiple downlink users with the required signal-to-interference-plus-noise ratio levels. Besides, we also take into account limitation radiated power by each antenna. formulated as quadratically constrained quadratic program joint-sparsity-promoting regularization, NP-hard. resulting solved consensus alternating direction method multipliers, enjoys parallel implementation. Numerical simulations exhibit effectiveness superiority proposed leads more power-efficient solution.
