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.
