Mode Selection in Cognitive Radar Networks

William W. Howard, Samuel R. Shebert, Anthony F. Martone +1

Cognitive Radar Networks, which were popularized by Simon Haykin in 2006, have been proposed to address limitations with legacy radar installations. These limitations include large…

Mode Selection and Target Classification in Cognitive Radar Networks

William W. Howard, Samuel R. Shebert, Benjamin H. Kirk +1

Cognitive Radar Networks were proposed by Simon Haykin in 2006 to address problems with large legacy radar implementations - primarily, single-point vulnerabilities and lack of ada…

Open and Closed-Loop Weight Selection for Pattern Control of Paraboloidal Reflector Antennas with Reconfigurable Rim Scattering

R. Michael Buehrer, William W. Howard, Steven Ellingson

It has been demonstrated that modifying the rim scattering of a paraboloidal reflector antenna through the use of reconfigurable elements along the rim facilitates sidelobe modific…

Timely Target Tracking in Cognitive Radar Networks

William W. Howard, Charles E. Thornton, R. Michael Buehrer

We consider a scenario where a fusion center must decide which updates to receive during each update period in a communication-limited cognitive radar network. When each radar node…

Model Order Estimation in the Presence of multipath Interference using Residual Convolutional Neural Networks

Jianyuan Yu, William W. Howard, Yue Xu +1

Model order estimation (MOE) is often a pre-requisite for Direction of Arrival (DoA) estimation. Due to limits imposed by array geometry, it is typically not possible to estimate s…

Decentralized Bandits with Feedback for Cognitive Radar Networks

William Howard, R. Michael Buehrer

Completely decentralized Multi-Player Bandit models have demonstrated high localization accuracy at the cost of long convergence times in cognitive radar networks. Rather than mode…

Distributed Online Learning for Coexistence in Cognitive Radar Networks

William Howard, Anthony Martone, R. Michael Buehrer

This work addresses the coexistence problem for radar networks. Specifically, we model a network of cooperative, independent, and non-communicating radar nodes which must share res…

Adversarial Multi-Player Bandits for Cognitive Radar Networks

William W. Howard, R. M. Buehrer, Anthony Martone

We model a radar network as an adversarial bandit problem, where the environment pre-selects reward sequences for each of several actions available to the network. This excludes en…

Multi-Target Localization Using Polarization Sensitive Arrays

William W. Howard, R. Michael Buehrer

In this work we develop clustering techniques for the Bearing Only Target Localization (BOTL) problem. Our scenario has a receiver move along some path, generating bearing estimate…
