2024 IEEE Conference on Computational Imaging Using Synthetic Apertures (CISA)

Join us for a co-hosted event with the IEEE Signal Processing Society, the IEEE Synthetic Aperture Standards Committee, and the IEEE Synthetic Aperture Technical Working Group at the NIST Boulder campus. Researchers and engineers will engage in cutting-edge research on computational imaging and sensing using synthetic apertures (SAs). 

The term SA refers generically to a discrete measurement scheme together with an inverse problem solution that yields imaging or sensing performance better than the hardware system is inherently capable of, e.g., wider field-of-view, higher angular resolution.  An SA may sample a propagating wavefield or environmental parameters in the signal domain via linear motion of an antenna or transducer, as in synthetic aperture radar (SAR), sonar (SAS), or channel sounding.  Alternatively, an SA may sample in the k-space domain via different look angles around an object or scene, as in computed tomography, spotlight SAR or Fourier ptychography.  Lastly, an SA may be constructed from a sparse array of sensors as in radiometry, seismology, or radio astronomy.  The front end of an SA may be a conventional antenna, acoustic transducer, or a quantum sensor, such as a Rydberg probe, in advanced implementations.  CISA will highlight advances in the theoretical development, engineering practice, and standardization of all aspects of SA imaging and sensing.
