【摘要】 在战场目标噪声自回归参数统计特征分析的基础上，以战场四种车辆噪声为背景，在自回归谱上提取了１２ 个单项特征，并借助于直方图和模糊识别论域分布图，对它们的识别效果进行了分析。更多还原

【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.更多还原
