Abstract

We describe a novel approach to target counting and speed estimation using the envelope of the seismic and acoustic signals. This approach is particularly well suited to low-cost, low-power sensors that lack the ability to determine target bearing and separation. We present methods for envelope peak detection, target detection, and speed estimation. Results of a field evaluation of one implementation of the algorithms are also presented.
