Earth Remote Sensing: An Overview
Spaceborne remote-sensing instruments are used for applications ranging from global climate monitoring to combat-theater weather tracking to agricultural and forestry assessment. Aerospace has pioneered numerous remote-sensing technologies and continues to advance the field.
The Best Laid Plans: A History of the Manned Orbiting Laboratory
In the mid to late '60s, an ambitious project to launch an orbital space laboratory for science and surveillance came to dominate life at Aerospace.
The Infrared Background Signature Survey: A NASA Shuttle Experiment
The development of remote sensing systems requires an accurate understanding of the phenomena to be observed. Aerospace research helped characterize space phenomena of interest to missile defense planners.
Active Microwave Remote Sensing
Active microwave sensing—which includes imaging and moving-target-indicating radar—offers certain advantages over other remote-sensing techniques. Aerospace has been working to increase the capability of this versatile technology.
Engineering and Simulation of Electro-Optical Remote-Sensing Systems
In designing remote-sensing systems, performance metrics must be linked to design parameters to flow requirements into hardware specifications. Aerospace has developed tools that comprehensively model the complex interaction of these metrics and parameters.
Data Compression for Remote Imaging Systems
Remote imaging platforms can generate a huge amount of data. Research at Aerospace has yielded fast and efficient techniques for reducing image sizes for more efficient processing and transmission.
Detecting Air Polution from Space
The use of satellite data for air-quality applications has been hindered by a historical lack of collaboration between air-quality and satellite scientists. Aerospace is well positioned to help bridge the gap between these two communities.
Synthetic-Aperture Imaging Ladar
Aerospace has been developing a remote-sensing technique that combines ultrawideband coherent laser radar with synthetic-aperture signal processing. The goal is to achieve high-resolution two- and three-dimensional imaging at long range, day or night, with modest aperture diameters.
Commercial Remote Sensing and National Security
Aerospace helped craft government policy allowing satellite imaging companies to sell their products and services to foreign customers—without compromising national security.
