Icebergs generated from ice ablation processes continue to be a threat for operations conducted in polar regions. Systems that have been developed to track and observe these threats often use either space-based radar imaging or visual observation by the crew of the ship. Both of these methods have disadvantages, mostly in terms of real-time observation or the physical abilities of the crew. We propose...
One of the key elements for building a long-term robotic companion is incorporating the ability for a robot to continuously learn and engage in new tasks. Utilizing a defined workspace that provides various shared content between human and robot could assist in this learning process. Here, we propose integrating a touchscreen tablet and a robot learner for engaging the user during human-robot interaction...
Ships that operate in polar regions continue to face the threat of floating ice sheets and icebergs generated from an ice ablation process. Systems have been implemented to track these threats, with varying degrees of success. In this paper, a definition is proposed for this tracking problem that re-casts it within a class of robotic, multiagent target observation problems. The focus in this new definition...
Environmental monitoring of spatially-distributed geo-physical processes (e.g., temperature, pressure, or humidity) requires efficient sampling schemes, particularly, when employing an autonomous mobile agent to execute the sampling task. Many approaches have considered optimal sampling strategies which specialize in minimizing estimation error, while others emphasize reducing resource usage, yet...
Converting measurements from sine-space coordinates to Cartesian coordinates has been shown to introduce biases into the measurements. This issue occurs in long-range radar or radars with high range resolution. Previous work that derived the expressions for these biases and provided methods for removing them has focused on the monostatic radar case. In our research, we have provided the equations...
The introduction of biases into monostatic radar measurements as a result of conversion from sine space coordinates into Cartesian coordinates is a well-known problem. Specifically, this problem occurs in long-range radars or radars with high range resolution. However, the biases have only been determined with regard to monostatic radars. With a possible resurgence in bistatic radar, specifically...
This paper describes a baseline target tracking system implemented using the GTRI/ONR Multiple-Input Multiple-Output (MIMO) Radar Benchmark platform. MIMO radar systems have been garnering a significant amount of attention for their potential to improve overall radar performance in comparison to existing systems. While there is much in the current literature regarding the performance and parameter...
With the growing amount of research being devoted to the concept of multiple-input multiple-output (MIMO) radar, there has been a lack of a common simulation and benchmarking environment for determining the viability and cost-effectiveness of MIMO radar architectures and algorithms. To this end, GTRI has developed a MIMO Benchmark environment to serve this purpose, which is to be made publically available...
