In this paper, we consider the problem of compressive radar sensing via one-bit sampling with time varying threshold. The system model and target detection problem are presented leading to a non-smooth optimization. To deal with this
sparse optimization problem, we propose an efficient algorithm based on alternating direction method of multipliers (ADMM) approach. The proposed method is then numerically compared with a benchmark in terms of solution accuracy and computational complexity. Simulation results illustrate that the proposed method significantly reduces the computational complexity while its solution almost coincide with the optimal one.
