| Abstract: |
A seismic-acoustic system can be detected from the air based on ground vibrations excited with an acoustic source, but current acoustic systems are too bulk and heavy. SARA proposes a combustion based system to create high intensity sound. The high energy density of hydrocarbon fuels allows for the creation of a lightweight compact system that compatible with the payload restrictions of UAV or light aircraft. SARA's innovative PD-CAAD technology harnesses the chemical energy to create high intensity sound at any desired frequency.
The current program is will focus on a laboratory demonstration of the demonstration of the technology. The results of the laboratory demonstrations will provide data for a Size Weight and Power (SWaP) trade study, system design, and conops design. The SWaP study will determine the ideal size for a given detection platform. SARA will then create a concept for a prototype design for testing in a phase II program. The design will include a conops analysis, which will consider how the military will deploy the technology in the field and integrate it with military operations.

| Benefits: |
The developed PD-CAAD technology will be a very compact, high intensity source of sound. The military urgently needs the technology as part of a system to detect mines and buried IEDs. Military mine detection systems measure the vibrations response of the ground to PD-CAAD's high intensity sound waves to uncover buried objects including mines. The entire system can be mounted on a lightweight aircraft, so personnel will no longer have to risk venturing into a mine field to determine the location of mines.
The technology will also see applications in the military, commercial, and homeland defense areas. The military can use the PD-CAAD as a very loud warning system, an acoustic hailing system, or as a battlefield distraction. Commercial versions of the technology will involve novelty and amusement applications. In homeland defense and law enforcement, the system can be used a non-lethal weapon, a high power hailing system, or as a warning system.
