Joint radar-communications waveform multiple access and synthetic aperture radar receiver

Radar and communications systems are often deployed in already crowded environments. The growing demand for additional communications users in frequency bands previously reserved for radar users motivates cooperation between these systems. One solution to the problem of radar-communications coexistence is to develop joint systems that simultaneously perform both tasks. One aspect of this co-design solution is to design waveforms simultaneously suitable for both systems' goals. Using a joint radar-communications waveform promises mutually beneficial performance gains while limiting spectral impact. We develop and simulate an example multiple access channel topology in which users simultaneously communicate and perform synthetic aperture radar imaging with a joint waveform. A joint radar-communications receiver is designed in the context of this example and shown to feasibly accomplish both systems' goals with a single waveform.
