High Resolution Time-Frequency Distribution for Maneuvering Target Detection in Over-The-Horizon Radars
A novel high-resolution time-frequency representation method is proposed for source detection and classification in over-the-horizon radar (OTHR) systems. A data-dependent kernel is applied in the ambiguity domain to capture the target signal components, which are then resolved using the root-MUSIC...
