Distributed Radar Imaging Based on Accelerated ADMM

no code implementations17 Jul 2023 Ahmed Murtada, Bhavani Shankar Mysore Rama Rao, Udo Schroeder

Alternatively, we proposed in an earlier work a joint reconstruction technique based on two problem formulations according to the optimization framework of the Alternating Direction Method of Multipliers (ADMM).

Widely Distributed Radar Imaging: Unmediated ADMM Based Approach

no code implementations10 Mar 2022 Ahmed Murtada, Ruizhi Hu, Bhavani Shankar Mysore Rama Rao, Udo Schroeder

While the problem is designed to promote a sparse solution for the global image, it is constrained such that a relationship with local images that can be reconstructed using the measurements at each sensor is respected.

Widely-distributed Radar Imaging Based on Consensus ADMM

no code implementations4 Nov 2020 Ruizhi Hu, Bhavani Shankar Mysore Rama Rao, Ahmed Murtada, Mohammad Alaee-Kerahroodi, Björn Ottersten

In this paper, a novel $l_1$-regularized, consensus alternating direction method of multipliers (CADMM) based algorithm is proposed to mitigate artifacts by exploiting a widely-distributed radar system's spatial diversity.
