Abstract: The various embodiments presented herein relate to utilizing an operational single-channel radar to collect and process synthetic aperture radar (SAR) and ground moving target indicator (GMTI) imagery from a same set of radar returns. In an embodiment, data is collected by randomly staggering a slow-time pulse repetition interval (PRI) over a SAR aperture such that a number of transmitted pulses in the SAR aperture is preserved with respect to standard SAR, but many of the pulses are spaced very closely enabling movers (e.g., targets) to be resolved, wherein a relative velocity of the movers places them outside of the SAR ground patch. The various embodiments of image reconstruction can be based on compressed sensing inversion from undersampled data, which can be solved efficiently using such techniques as Bregman iteration. The various embodiments enable high-quality SAR reconstruction, and high-quality GMTI reconstruction from the same set of radar returns.

Abstract: Methods for image based localization using an electronic computing device are presented, the methods including: capturing a local image with an image capture device; associating metadata with the local image; causing the electronic computing device to receive the local image; causing the electronic computing device to match the local image with a database image, where the database image is three-dimensional (3D); and calculating a pose of the image capture device based on a pose of the database image and metadata associated with the local image. In some embodiments, the metadata includes at least pitch and roll data corresponding with the image capture device at a time of image capture.
