摘　　要：本文从理论上分析了分数相关器的分数级次对相关输出面能量分布的影响 ,利用数值模拟方法 ,对基于匹配滤波结构的分数相关器畸变不变模式识别特性进行了深入的讨论 ,并与传统相关器进行了比较 .结果表明在畸变不变模式识别中 。In this paper,the impact of the orders of fractional correlator on the energy distribution of the correlation plane is analyzed theoretically,and then the performance of fractional correlator for distortion invariant pattern recognition is discussed deeply by numerical method based on the matched filtering configuration.A comparison is made with the conventional correlation that shows the fractional correlation possess more powerful capability of distortion invariant pattern recognition than that of the conventional correlation.
