A Novel MIMO–SAR Solution Based on Azimuth Phase Coding Waveforms and Digital Beamforming [PDF]

Sensors, 2018
In multiple-input multiple-output synthetic aperture radar (MIMO–SAR) signal processing, a reliable separation of multiple transmitted waveforms is one of the most important and challenging issues, for the unseparated signal will degrade the ...

Intra-pulse Spotlight SAR Imaging Method Based on Azimuth Phase Coding

Leida xuebao, 2018
The intra-pulse spotlight imaging mode can effectively overcome the contradiction between high resolution and wide swath in spaceborne Synthetic Aperture Radar (SAR), and considers the echo’s signal-tonoise ratio.
