Waveform selection for spaceborne sparse aperture MTI radar

Sparse aperture MTI radar has several potential advantages, but challenges associated with grating lobes, coverage area, and system timing must be overcome. Waveform selection, especially in the form of waveform diversity, provides methods for mitigating these issues. We present a detailed overview of issues involved in waveform selection applied to sparse arrays. We also present processing flows for waveform diversity and some supporting numerical results.
