Evaluation of target detection methods and the study of accuracy improvement toward the application to MDA with hyperspectral imaging

摘要

In recent years, Maritime Domain Awareness (MDA) has become important for national defense in Japan. Target detectionusing hyperspectral data is useful for MDA. In this study, we found that Correlation Matched Filter (CMF) has a betterdetection accuracy than Spectral Matched Filter (SMF), both of which are derived from Reed-Xiaoli Detector. CMF doesn'tneed to calculate the average value of the background spectrum, which is also advantageous in real-time processing. Inaddition, we could also show that it is possible to improve the detection accuracy by band selection in CMF. This increasesthe detection accuracy of foreign matter on the ocean.
