Author Affiliations +
Perimeter security is of increasing importance, both for Homeland security and a variety of related applications. Infrared (IR) imaging systems in a variety of configurations can provide a compact, cost effective solution for day/night long-range visual site perimeter surveillance. Over the past year, L-3 Communications Cincinnati Electronics (L-3 CE) has fielded currently available electro-optic/IR imaging systems with several configurations of optics and focal plane array (FPA) detector format to collect digital data on man and vehicle targets. The purpose of these deployments was to assess compatibility with existing sites and determine identification ranges. Of key interest to L-3 CE were the comparison of predicted night vision performance to field data at ranges up to ten kilometers, comparison of daytime and nighttime operation, and the population of an image database for future in-camera image enhancement algorithms. This paper provides information on the configuration of the imager, pan/tilt head, and data control/collection system, environmental conditions, and range performances achieved for the various test sites. It includes a summary of the data collected with sample imagery from the collection activities. This paper concludes with the results of data analysis, plans for future data collections, and implementation into ground based sites.
