Abstract
Landmines and buried improvised explosive devices (IED) represent a clear and present danger to the modern U.S. warfighter. The ability to survey a potentially hazardous area from the air using an unmanned aerial vehicle (UAV)-mounted optical acoustic system has the potential to greatly reduce causality rates. However, existing acoustic sources are inadequate to stimulate the earth at the necessary levels or frequencies from the desired altitudesa new, compact, efficient, and intense sound source is needed. In this effort, Creare proposes to develop a Compact Airborne Acoustic Transmitter (CAAT) capable of stimulating the ground at 100 dB over the 90 to 400 Hz frequency range from an altitude of 1,000 feet. The CAAT combines an innovative, highly efficient acoustic source with a novel, efficient, and directional acoustic horn to maximize the sound pressure level on the ground. Creare has assembled a highly qualified team for this development effort. In Phase I, we will compare the designs of two sound sources and numerically optimize the shape of the acoustic horn. In Phase II, we will interface the subsystems and build, test, validate and deliver to the Navy a prototype of the required size, shape, weight, power consumption, and acoustic output.
