Compact Acoustic - Seismic Unattended Ground Sensor

Acoustic and seismic sensors have become the technology of choice for Unattended Ground Sensors. Military vehicles have loud and distinctive signatures which can be detected at remarkable distances. In order to minimize the size and cost of the proposed sensors, SenTech proposes to use a single microphone and a three component geophone as the sensor's transducers. SenTech's proposals incorporate several innovative techniques that will be combined to achieve a higher level of performance than what has been achieved today in any other Unattended Ground Sensor system. Advanced seismic processing techniques will be used to remove the acoustically - coupled components and determine the direction of the vehicle. Adaptive resolution spectral analysis will be used to maximize the available signal to noise ratio when the sources are non-stationary. Knowledge-based classification algorithms will be used to identify targets and interpret field activities. The small size of the devices will allow the sensors to be delivered from helicopters of remotely piloted aircraft of hand emplaced by soldiers. When multiple sensors provide overlapping coverage over an area of interest, their results can internetted to produce a more accurate localization of a source.
