Abstract

In this paper an extended robust independent components analysis algorithm based on cumulants is applied to identify vibrational alarm signals generated by soldier termites in southern Spain (reticulitermes grassei), measured using low cost equipment. A seismic accelerometer is employed to strongly characterize these acoustic emissions. To support the proposed technique, vibrational signals from a low cost microphone have been mixed with known signals, and the mixtures processed by ICA. The experimental results confirm the validity of the proposed method, which has been taken as the basis for the development of a low cost, noninvasive, termite detection system.
