摘　　要：从理论上分析了分数相关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 ,对分数相关尺度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。结果表明在尺度畸变不变模式识别中 。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 scale distortion-invariant pattern recognition is discussed in detail by using numerical method based on the matched-filtering configuration. A comparison is made with the conventional correlation that shows the fractional correlation possesses more powerful capability of scale distortion invariant pattern recognition than that of the conventional correlation.
