• Resource optimization and scheduling
• Image analyst training
• Ground station operation and management

Synthetic Aperture Radar (SAR) system
The synthetic aperture radar (SAR) system allows General Dynamics' customers to view ground-level details through clutter above, such as clouds and fog. SAR illuminates a scene through microwaves and records both the amplitude and the phase of the back-scattered radiation, creating a coherent image.

An inherent feature of this type of imaging is speckle, which arises because each resolution cell contains many scatterers. The phases of the return signals from these scatterers are randomly distributed and speckle is caused by the resulting interference.

Major products using SAR technologies:

Image Chain Engineering
Sentry
DCS
Exploitation
