匹配滤波识别相关峰的分析与实验判别
Analysis and Experimental Determination for Matched Filtering Recognition of Correlation Peak
摘要
能否输出相关峰是相关器判定目标真伪的主要方式,但其元件调节精准度不高时,容易对相关峰产生误判。基于匹配滤波相关识别器,从理论上分析了相关峰产生误判的3种可能,重点对相关信号的强度判别进行了理论和实验研究,针对这3种可能产生误判的情况,分别从实验结果的相关峰阈值强度、形态、输入图像旋转方面探讨真伪相关峰的判别,为相关峰的判别提供实验参考。
Abstract
Whether correlators can output correlation peak is the main way to determine the target authenticity of correlators. However, it is prone to misjudgment when the accuracy of the components adjustment is not high enough. Based on the matched filtering correlators, we make theoretical analysis of three cases about the misjudgment of the correlation peaks. We give special emphasis to the theoretical and experimental study on correlation signal strength discrimination. Considering the three cases about the misjudgment of the correlation peaks, we explore the judgment of correlation peaks from the threshold intensity and the form of the correlation peaks, and the angle of rotation of the input image, which provide reference for experimental determination of the correlation peak.
