Research on Unconstrained Phase-Only Matched Filtering Design

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.
