| Abstract: | Based on the statistic feature analysis of the autoregression parameters for the noises of battlefield target,twelve features are extracted in the autoregression spectrum against the background of the noises of four kinds of battlefield vehicles. And their recognition effects are analyzed by means of a pictorial block diagram and fuzzy recognition statement field distribution diagram. |
