Abstract

The Early Attack Reaction Sensor (EARS) is a modified passive acoustic system that detects gunshots (muzzle blast and/or shockwave) to provide the user with relative azimuth and range of sniper fire via both audio alert and visual display. The EARS system consists of a microphone array in a small planar configuration and an equivalently sized Digital Signal Processing board, which is interfaced to a PDA via a PCMCIA slot. Hence, configuration easily provides portability. However, the system is being repackaged for man-wearable and vehicle mount applications. The EARS system in a PDA configuration has been tested in open fields at up to 500 meters range and has provided useable bearing and range information against the sniper rounds. This paper will discuss EARS system description, various test results, and EARS system capabilities and limitations.
