ABSTRACT
The ubiquity of millimeter-wave (mmWave) technology could bring through-obstruction imaging to portable, mobile systems. Existing through-obstruction imaging systems rely on Synthetic Aperture Radar (SAR) technique, but emulating the SAR principle on handheld devices has been challenging. We propose ViSAR, a portable platform that integrates an optical camera and mmWave radar to emulate the SAR principle and enable through-obstruction 3D imaging. ViSAR synchronizes the devices at the software-level and uses the Time Domain Backprojection algorithm to generate vision-augmented mmWave images. We have experimentally evaluated ViSAR by imaging several indoor objects.

Millimeter-Wave Interferometric Synthetic Aperture Radar Imaging via Ground Projection
CSE '14: Proceedings of the 2014 IEEE 17th International Conference on Computational Science and EngineeringDue to the short wavelength, Millimeter-wave interferometric synthetic aperture radar (MMW-In SAR) imaging requires higher precision of the platform trajectory compared with other centimeter-wave bands. In the case of non-ideal trajectory, traditional ...

ICIP '95: Proceedings of the 1995 International Conference on Image Processing (Vol. 1)-Volume 1 - Volume 1This paper presents an interferometric processing of an aircraft's monostatic and bistatic inverse synthetic aperture radar signatures for automatic landing. The aircraft's squint angle in this ISAR imaging problem is near 90 degrees. We show that this ...
Accurate device self-tracking for robust millimeter-wave imaging on handheld smart devices
MobiSys '22: Proceedings of the 20th Annual International Conference on Mobile Systems, Applications and ServicesMillimeter-wave (mmWave) imaging has been difficult to implement on handheld devices since imaging algorithms rely on millimeter-scale device self-tracking, which existing systems cannot achieve reliably. We propose CompenSAR, a handheld system which ...
