unattended ground sensors (UGS) provide surveillance, intelligence, and monitoring of areas not suitable for continuous human presence. Current state-of-the-art UGS are larger and heavier than desired and usually are limited to one or two types of sensors. Northrop Grumman is developing the next generation UGS which is called the Miniaturized unattended ground sensor (Mini-UGS). The Mini-UGS will employ a modular concept which allows the UGS to be reconfigured as mission requirements change. Multiple types of sensors and/or radios can be interchangeable on the Mini-UGS. In order to make the Mini-UGS a reality, several critical technologies such as low power processor architectures, rugged communication bus, and package hardening techniques are under development. This paper presents the Mini-UGS concept and the critical technologies of which it is composed.

320 X 240 and 640 X 480 small pixel uncooled microbolometer focal plane arrays have been developed that reduce overall sensor size, weight, power consumption, and cost. At the same time, these sensors still provide the high quality image resolution needed for target recognition and identification. These newly developed small uncooled thermal imaging sensors are being demonstrated in several attended and unattended sensor applications that include unattended ground sensors, Micro Air Vehicles, and Infrared Helmet Sights. This paper describes recent developments at BAE SYSTEMS in uncooled microbolometer sensor technology for unattended sensor applications and presents the latest performance and image data for our 2(nd) generation systems.

conference on unattended ground sensor technologies and applications VII

In this paper we examine the different functions performed by an acoustic-seismic unattended ground sensor (UGS) and how they contribute to the overall cost of the sensor and its implementation. A key point made is that the performance of the acoustic-seismic depends on target characteristics and environmental conditions and cannot easily be traded off against implementation costs. At the present time, sensor implementation costs are dominated by the radios. In general, it is best to use radios whose range is consistent with the detection capabilities of the sensors. Dense networks of sensors using short-range radios supporting distributed communication architecture will produce an unnecessary duplication of coverage and a much-increased cost. Different scenarios for the utilization of acoustic-seismic UGS are examined, and evaluated with respect to their implementation costs. The most cost-effective use of acoustic-seismic sensors is in those applications where they can use satellite communications or tap into an existing communications network.

This paper describes the use of unattended seismic and acoustic unattended ground sensors (UGS) for aircraft detection and activity categorization. Such systems were tested for these purposes and found to be particularly effective. The multi-modal sensor system discussed here was tested in September of 2005 and again in January of 2006. Test results are detailed and conclusions about the way ahead are drawn to facilitate further research.

A low-power hardware platform and a software framework to support distributed wireless sensing for unattended ground sensor (UGS) applications has been developed. This platform provides a comprehensive set of hardware capabilities needed to meet the sensing, processing, and communication requirements for UGS, including a 16-channel analog interface, a processor dedicated to managing real-time requirements, dual wireless interfaces, and a low-power system bus to enable system modularity. An open software framework based on the Linux kernel is hosted on the main system processor. This framework incorporates the tools for effectively utilizing the capabilities of the hardware platform and rapidly developing applications in a networked, embedded environment.

Progress in several technical areas is being leveraged to advantage in unattended ground sensor (UGS) systems. This paper discusses advanced technologies that are appropriate for use in UGS systems. While some technologies provide evolutionary improvements, other technologies result in revolutionary performance advancements for UGS systems. Some specific technologies discussed include wireless cameras and viewers, commercial PDA-based system programmers and monitors, new materials and techniques for packaging improvements, low power cueing sensor radios, advanced long-haul terrestrial and SATCOM radios, and networked communications. Other technologies covered include advanced target detection algorithms, high pixel count cameras for license plate and facial recognition, small cameras that provide large stand-off distances, video transmissions of target activity instead of still images, sensor fusion algorithms, and control center hardware. The impact of each technology on the overall UGS system architecture is discussed, along with the advantages provided to UGS system users. Areas of analysis include required camera parameters as a function of stand-off distance for license plate and facial recognition applications, power consumption for wireless cameras and viewers, sensor fusion communication requirements, and requirements to practically implement video transmission through UGS systems. Examples of devices that have already been fielded using technology from several of these areas are given.

Networks of unattended ground sensors are fast becoming a reality, but little attention has been paid to date to the problem of how to plan an effective deployment of these sensors. Since the performance of the networked sensors depends on weather, target type, communications, terrain. and on how the sensors cooperate, the problem of planning a deployment is a very complex one. We will show how these factors can be included in a deployment planning tool that allows the warfighter to plan a deployment of acoustic sensors in near-real time. This tool can also be used as a health-monitor for the network of sensors, allowing the warfighter to maintain the network of sensors at a level of effectiveness needed to meet the mission goals.

NATO's Task Group (TG-25) on acoustic and seismic sensing is responsible for assessing the potential technologies that can be cooperatively developed and shared within NATO's countries to provide effective, robust and low-cost battlefield sensor systems. The primary emphasis is the concept of unattended ground sensors (UGS) for the detection and/or classification of ground and airborne vehicles, artillery and sniper fire. TG-25 has 3 main objectives: (1) to establish acoustic and seismic standards and data exchange procedures, (2) to compare, analyze, exchange, and develop analytical techniques, computational models and signal processing algorithms, and (3) to plan and conduct joint field experiments In this paper, we discuss participation in the joint NATO field experiment conducted in France in October 2002. The experiment's goal was to demonstrate interoperability of unattended ground sensors from various participating nations. Results of the experiments will be briefed and discussed.
