Paper Abstract

changed substantially and that surveillance systems designed to operate against heavy armor following conventional tactics have to adapt to a “New Threat” environment. This observation is very pertinent to the use of acoustic and seismic sensors. These sensing modalities have been used with success against a threat consisting of armored vehicles powered by large Diesel engines. In the type of conflicts that we are likely to encounter in places like Afghanistan, Yemen and other SE Asian countries, US forces will be faced by a threat that can move about in converted civilian vehicles, Figure 1. Systems like the Wide Area Mine (a.k.a. Hornet) and the Brilliant Anti-Tank Munition (BAT) exploited the loud and distinctive signatures of combat vehicles to direct their fire control system. Other surveillance systems such as Steel Rattler / Steel Eagle and DARPA’s Micro-IUGS focused on “high value targets”, also military vehicles of considerable size. All of these target vehicles are powered by large, noisy diesel engines and have large tires or tracks that produce substantial seismic signatures.The object of this paper is to present an analysis of the signatures of civilian vehicles that may be adapted to military or terrorist activities. We will then look at the sensor configurations that are best adapted to detect and track these vehicles. Some examples of the type of surveillance data that we can obtain are also shown in the paper.
