Aimed at the characteristics of the wireless sensor networks
an improved algorithm is presented for signal dectection in order to reduce the false alarm rate
by using battlefield vehicle acoustic signal.Wavelet packet transform is used to extract 16-dimensional signal feature
support vector machine in classifing target.Energy-based global decision fusion algorithm is proposed to work out the final result.For evaluation purposes
real data are used from DARPA’s SensIT project
which contains lots of acoustic signals of two types of vehicle
a tracked vehicle and a heavy truck.The experiment results show that the algorithm is valid for battlefield vehicle classification based on wireless sensor networks.
