Neural Volumetric Reconstruction for Coherent Synthetic Aperture Sonar
Synthetic aperture sonar (SAS) is an active acoustic imaging technique that coherently combines data from a moving array to form high-resolution imagery, especially of underwater environments. The moving array in SAS collects both magnitude and phase information which allows coherent integration methods to achieve resolution parallel to the sensor...

Improving Angle Estimation Accuracy for Millimeter-Wave Radars
Radar systems transmit electromagnetic waves through the air and the objects in the aperture reflect the signal. The reflected signal is captured by the radar to find the position, angle, and velocity of each object. Millimeter-wave (mmWave) radar is a subclass of radar systems that uses millimeter waves to operate. The main advantage of mmWave radars...

Efficient Multi-Bit Reconfigurable Reflective Surface (RRS) for mmWave and Terahertz Applications
Background Reflective surfaces, including metasurfaces and reflectarray antennas, are comprised of several subwavelength (< λ/2) passive reflective elements and can steer the reflection of an incident electromagnetic wave in arbitrary directions. Typically, reflective surfaces use one or multiple single-pull-single-through (SPST) switches...

CSVideoNet: A Real-time End-to-end Learning Framework for High-frame-rate Video Compressive Sensing
CSVideoNet: A Real-time End-to-end Learning Framework for High-frame-rate Video Compressive Sensing Background High-frame-rate cameras are capable of capturing videos at frame rates over 100 frames per second (fps). These devices were originally developed to characterize rapid events. Some high-frame-rate cameras can record high resolution still images...

MIST: Missing Person Intelligence Synthesis Toolkit
Missing person cases have been on the rise in the United States for the past twenty years. Currently, approximately 4,000 people go missing every day. Of those 4,000 cases, over 500 missing person cases go unsolved per day. Furthermore, many of these missing person cases are associated with human trafficking. By utilizing software tools, resources can...
