For deep space communication systems, the decision of whether or not to suppress the transmitted carrier has always been an issue. For certain missions that use high data rates, the available bandwidth might be a limiting factor. In such cases, it is preferred to use a...

This software implements a new probabilistic framework for integrated multi-target detection and tracking of small moving objects in image sequences, with specific application to tracking people in aerial images, in which image stabilization is inherently noisy.

The Neo-Geography Toolkit (NGT) is a collection of open-source software tools for the automated processing of geospatial data, including images and maps. It can process raw raster data from remote sensing instruments and transform it into useful cartographic products such as visible image base maps, topographic models,...

This invention allows the verification and identification of a person based on features extracted from one or more electrocardiographic leads or channels. For identification purposes, the invention can be used to identify a subject from a group of known subjects. For...

This technology was developed for the Soil Moisture Active Passive (SMAP) mission and for the IRAD-FY13 Technology for Radiometer RFI Noise Detection & Mitigation Based on HHT2. Spacecraft beyond the present state-of-the-art passive radiometry will make use of natural...

A low-cost optical element was developed specifically for neutron optics applications. The technology operates as a reflective lens — similar to proven grazing incidence optics used for x-ray imaging — and improves neutron imaging resolution for applications using low-energy (<1...

Sunlight can be reflected into permanently shadowed regions (PSRs) using S/C solar sails in order to detect and confirm the presence and distribution of water ice cold-trapped in PSRs in lunar polar craters. This reflected light is then viewed with an optical spectrometer.
