Acoustical detection of gunshots in the open
Hrabina, M.,
This paper descibes development of reliable gunshot detection system without need of localization, with emphasis on low power consumption for use in counter-poacher devices primarily protecting elephants in Africa. Intended system will work as a binary detector of gunfire without further classification of used fire-am. Dominance of right gunshot detection over false alarm is crucial. Recognition systém is based on LPC coefficients, correlation against template and comparison of spectal energy in sub-bands.
