Enhanced Pre-STAP Beamforming for Range Ambiguous Clutter Separation with Vertical FDA Radar
Remote Sensing, 2021 Medium pulse repetition frequency (MPRF) is an important mode in airborne radar system. Since MPRF mode brings both Doppler and range ambiguities, it causes difficulty for the airborne radar to suppress ground or sea clutter. In recent years, it has been
