Short summary
Our paper reviews orthogonal waveforms for spaceborne Multiple-Input Multiple-Output Synthetic Aperture Radar (MIMO-SAR), a first-of-its-kind comparison. We provide a catalogue of waveform performance parameters and an ambiguity function analysis, serving as decision rules for optimal waveform selection in MIMO-SAR design.
