Vessel Velocity-Driven SAR Phase Refocusing for Moving Vessel Recognition

Year: 2024

Type: article

Abstract: In this study, a synthetic aperture radar (SAR) phase refocusing algorithm using vessel velocity was proposed and applied to three different satellite SAR images in order to enhance the recognition performance of moving vessels.Exploiting the Doppler frequency character of target velocity, it effectively calibrates azimuth defocusing and aids vessel recognition by using the well-focused image as training data.Refocusing performance on vessels exceeded that of the conventional autofocusing algorithm, while vessel recognition accuracy was enhanced after performing the refocusing.
