The performance of frequency modulated continuous wave (FMCW) radar in tracking targets is presented and analysed. Obstacle detection, target tracking and radar target tracking performance models are developed and were used to investigate and to propose ways of improving the autonomous motion of unmanned surface vehicle (USV). Possible factors affecting the performance of FMCW radar in tracking...

This paper presents the concept of unmanned vehicle situation awareness and provides a discussion of how unmanned vehicle situation awareness can be defined based upon human situation awareness. A broadly accepted human situation awareness definition is directly applied to the notion of unmanned vehicle situation awareness. The paper also discusses unique unmanned vehicle aspects that will infl...

Unmanned Ground Vehicle (UGV) technology plays a key role in Oshkosh Truck Corporation’s (Oshkosh’s) efforts to supply the American military forces and their allies with the tools they need. The US Congress has set an aggressive goal, targeting that one-third of all operational ground combat vehicles will be unmanned by 2015. In working with the armed forces to meet this goal, Oshkosh continues...

The studies in aerial vehicles modeling and control have been increased rapidly recently. In this paper , a coordination of two types of heterogeneous robots , namely unmanned aerial vehicle (UAV) and unmanned ground vehicle (UGV) is considered. In this paper the UAV plays the role of a virtual leader for the UGVs. The system consists of a vision- based target detection algorithm that uses the ...

The purpose of a data acquisition system is to provide reliable and timely information. The received information can be then analyzed in real-time or remotely to assess the state of the measured environment. Similarly, for an autonomous underwater navigation system it is critical to analyze the data received from the inertial measurement unit and other acoustic sensors to calculate its position...

This paper describes a decision-theoretic approach to cooperative sensor planning between multiple autonomous vehicles executing a military mission. For this autonomous vehicle application , intelligent cooperative reasoning must be used to select optimal vehicle viewing locations and select optimal camera pan and tilt angles throughout the mission. Decisions are made in such a way as to maximi...

Author: Trevor Peterson Title: Effect of Time Pressure and Task Uncertainty on I luman Operator Performance and Workload for Autonomous Aerial Vehicle Missions Institution: Embry Riddle Aeronautical University Year: 2010 Unmanned aircraft systems (UAS) are being utilized at an increasing rate for a number of military applications. The potential for their use in the national airspace is also of ...

Formal verification of agents representing robot behaviour is a growing area due to the demand that autonomous systems have to be proven safe. In this paper we present an abstract definition of autonomy which can be used to model autonomous scenarios and propose the use of small-scale simulation models representing abstract actions to infer quantitative data. To demonstrate the applicability of...

Future unmanned systems in the military will be highly heterogeneous in nature, with vehicles from multiple domains—aerial, underwater, and land—working in collaborative teams to complete a variety of missions. The complexity of supervising these teams will be enormous and will rely on human creativity, judgment, and experience. Therefore, the design and development of mission planning and moni...

Unmanned vehicles have been the focus of active research on autonomous motion planning, both deliberative and reactive. However, they are fundamentally limited in their autonomy by an inability to independently reason about, prioritize, and change the goals they pursue. We describe two new projects in which we are incorporating goal autonomy on unmanned vehicle platforms. We will apply the Goal...
