Research on Unconstrained Phase-Only Matched Filtering Design

根据非约束相关匹配滤波器和纯相位匹配滤波器的概念,分析了非约束纯相位匹配滤波器的特性及其在光学相关识别中的应用,并与其他典型纯相位匹配滤波器进行了比较.模拟和实验结果表明,非约束纯相位匹配滤波器具有畸变容限大、相关峰高、算法简单的特点.用于光学相关识别是一种实用的空间匹配滤波器算法.

Based on the conception of unconstrained correlation filter and phase-only matched filter,the characteristics and application of the filter was analyzed,and it has been compared with other typical phase-only matched filters.Simulation and experiment show that the features of unconstrained phase-only matched filter are that correlation peak is higher and distortion tolerance is larger and arithmetic is simpler.It is an arithmetic that can be applied well in the correlation recognition.
