Acoustic detection of gunshots has many applications

in the field of security and military. This paper deals with

the detection of gunshots, using microphone sensor arrays placed

in different locations which are processed using MATLAB. The

time difference of arrivals of acoustic signals at different sensors

is used to determine the direction of arrival, elevation and the

location of the shooter. The aim of the project is to develop a

high speed, low power sensor array which can be used for both

military and civilian safety along with efficient network security.

A mathematical model will be developed and five microphone

system will be used in localizing the gunshot.
