ISAR Imaging Motion Compensation in Low SNR Environments Using Phase Gradient and Filtering Techniques
IEEE Transactions on Aerospace and Electronic Systems（2021）
摘要
In a low signal-to-noise ratio (SNR) environment, conventional range profiles-based motion compensation (MoCo) methods become inapplicable for inverse synthetic aperture radar (ISAR) imaging. In this article, a novel method for range profile alignment along with phase adjustment is proposed. The method is applied in the uncompressed phase history domain without the need for a prominent point. Moti...
