Abstract
Determining the location of an explosive event using a networked sensor system within an acceptable accuracy is a challenging problem. McQ has developed such a system, using a mesh network of inexpensive acoustic sensors. The system performs a three-dimensional, time-difference-of-arrival (TDOA) localization of blasts of various yields in several different environments. Localization information of the blast is provided to the end user by exfiltration over satellite communications. The system is able to perform accurately in the presence of various sources of error including GPS position, propagation effects, temperature, and error in determining the time of arrival (TOA). The system design as well as its performance are presented.
