The operational Lifetime of an unattendedgroundsensor (UGS) depends on the power consumption of the package and the space allocated for batteries. Solar cells have the potential of dramatically increasing operational lifetimes of UGS instruments by providing supplemental power, but in this application solar cells are subject to a number of non-traditional constraints. There are UGS applications where the solar array will need to be covert or have a high shock resistance. It is also possible that a UGS-solar array will be placed in a shaded area or randomly oriented with respect to the path of the sun. This paper will first survey conventional approaches towards solar battery charging and then discuss non-conventional approaches applicable to randomly oriented and covert UGS solar cell arrays.

New opportunities for battlefield surveillance and modeling are unfolding with the advent of smart sensors linked via digital wireless networks. One exciting prospect is the use of tomogaphic techniques in order to create real-time three-dimensional modeling and analysis of the environment that is immediately accessible to battlefield forces. We have developed a small-scale groundsensor network for this application. We discuss initial deployment of this network as a tracking system.

This paper extends our development of acoustical bearings-only target localization for the case of multiple moving targets. The resulting techniques can be used to locate and track targets traveling through a network of acoustical sensor arrays. Each array computes and transmits multiple, direction-of-arrival (DOA) estimates to a central processor, which employs the target localization technique. In previous work, we developed ML techniques that may or may not account for the fact that a bearing measurement points to the location of a moving target at a retarded time. By inserting a simple bearings association computation in the ML methods., we define quasi-ML techniques that can estimate the location and velocity of multiple targets using multiple bearing estimates per a sensor array.

Starting in the early 1990's, uncooled microbolometer thermal imaging sensor technology began to move out of the basic development laboratories of the Honeywell Corporation in Minneapolis and into applied development at several companies which have licensed the basic technology. Now, this technology is addressing military, government, and commercial applications in the real world. Today, thousands of uncooled microbolometer thermal imaging sensors are being produced and sold annually. At the same time, applied research and development on the technology continues at an unabated pace. These research and development efforts have two primary goals: 1) improving sensor performance in terms of increased resolution and greater thermal sensitivity and 2) reducing sensor cost. Success is being achieved in both areas. In this paper we will describe advances in uncooled microbolometer thermal imaging sensor technology as they apply to the modem battlefield and to unattendedgroundsensorapplications in particular. Improvements in sensor performance include: a) reduced size, b) increased spatial resolution, c) increased thermal sensitivity, d) reduced electrical power, and e) reduced weight. For battlefield applications, unattendedsensors are used not only in fixed ground locations, but also on a variety of moving platforms, including remotely operated ground vehicles, as well as Micro and Miniature Aerial Vehicles. The use of uncooled microbolometer thermal imaging sensors on these platforms will be discussed, and the results from simulations, of an uncooled microbolometer sensor flying on a Micro Aerial Vehicle will be presented. Finally we will describe microbolometer technology advancements currently being made or planned at BAE SYSTEMS. Where possible, examples of actual improvements, in the form of real imagery and/or actual performance measurements, will be provided.
