The method of empirical mode decomposition(EMD) was used for the signal processing and feature abstracting of acoustic target of battle field.According to the signal’s characteristics of different targets, some feature vectors in token of the target properties were constructed and abstracted.In the basis of feature abstracting and statistic analysis for large amount of sample signal of the targets, using the maximum subjection classification method based on the fuzzy synthesis judgment, the three typical acoustic target helicopter, tank and traffic vehicle were recognized.
