Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. [1] SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars.
The main advantage of the STAR architecture is that it requires no mechanical scanning of an antenna. Using a static antenna simplifies the antenna system dynamics and improves the time-bandwidth product of the radiometer. Furthermore, aperture thinning reduces the overall volume and mass of the antenna system.

Synthetic aperture radar (SAR) allow for an angular resolution beyond real beamwidth by moving the aperture over the target, and adding the echoes coherently. Architecture: The field of view is scanned with a highly directive frequency-orthogonal (slotted waveguide), spatially orthogonal (switched beamforming networks), or time-orthogonal beams.
Radar programs focus on the development, analysis, and performance evaluation of radar systems; reflectivity and propagation measurement characterization; electronic attack and protection techniques; avionics integration; non-cooperative target identification; vulnerability analysis; signal processing techniques; ground and airborne moving target identification; synthetic aperture radar; and ...
The radar is capable of producing extremely high resolution images at long range. ASARS-2 was used extensively during Operation Desert Storm for target location and battle damage assessment. It has also been used to survey damage after various domestic disasters, including floods along the Mississippi River and the 1994 Northridge earthquake .
The AN/APG-68(V)9 [6] radar system consists of the following line-replaceable units: Antenna; Medium Duty Transmitter (MDT) Modular Receiver/Exciter (MoRE) Common Radar Processor (CoRP) The AN/APG-68(V)9 radar is the latest development. Besides the increase in scan range compared to the previous version, it has a Synthetic aperture radar (SAR ...
Future Imagery Architecture (FIA) was a program awarded to Boeing to design a new generation of optical and radar imaging US reconnaissance satellites for the National Reconnaissance Office (NRO). In 2005 NRO director Donald Kerr recommended the project's termination, and the optical component of the program was finally cancelled in September ...
