Air Force Boom Event Analyzer Recorder (BEAR): System Description

Abstract

Developed, tested, built and used in field studies were several Boom Event Analyzer REcorders (BEARs). These BEAR's operate unattended to capture the wave form of Impulsive Acoustic Events (e.q. Sonic Booms) and their time of occurrance while excluding all other acoustic events. These BEARs are designed to operate unattended for up to 10 days and can store over 50 normal (less than 250 miliseconds in duration) sonic booms. These BEAR systems have been used successfully to capture the sonic boom signature from all US supersonic aircraft. This report is a complete system description of the BEAR covering data collection, theory of operation, data storage and retrieval, operation and complete hardware and software description. The comparison test done in cooperation with NASA and field studies using these BEARs are detailed in companion reports. (JHD)
