【Abstract】 This paper is intended to explore the effectiveness of battlefield targets classification and identification according to the characteristics of acoustic and seismic signals using ANN (Artificial Neural Network). Acoustic/seismic test and analysis system for typical battlefield targets is developed and properties of targets are acquired. Aiming at solving the drawback of extremely slow convergence speed of normal BP algorithm, a reformed BP algorithm is adopted to train the classifier. It is demonstrated that the reformed BP algorithm has higher correct identification rates for acoustic and seismic signals of battlefield targets according to signal sample experiments of typical targets, and the ANN classifier is suitable for the classification of battlefield targets.更多还原
