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.

Coexistence of Communications and Cognitive MIMO Radar: Waveform Design and Prototype

no code implementations8 Mar 2021 Mohammad Alaee-Kerahroodi, Ehsan Raei, Sumit Kumar, Bhavani Shankar Mysore Rama Rao

New generation of radar systems will need to coexist with other radio frequency (RF) systems, anticipating their behavior and reacting appropriately to avoid interference.

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.

Reconfigurable and Intelligent Ultra-Wideband Angular Sensing: Prototype Design and Validation

no code implementations13 Aug 2020 Himani Joshi, Sumit J. Darak, Mohammad Alaee-Kerahroodi, Bhavani Shankar Mysore Rama Rao

The emergence of beyond-licensed spectrum sharing in FR1 (0. 45-6 GHz) and FR2 (24 - 52 GHz) along with the multi-antenna narrow-beam based directional transmissions demand a wideband spectrum sensing in temporal as well as spatial domains.
