Called synthetic aperture radar (SAR), an ordinary-sized antenna fixed to the side of an aircraft is used with highly complex signal processing to give an image that would otherwise require a much larger, scanning antenna; thus, the name synthetic aperture. As each pulse is emitted, it is radiated over a lateral band onto the terrain.
The Advanced Synthetic Aperture Radar System-2 (ASARS-2) is the radar system mounted on some variants of the Lockheed U-2 reconnaissance aircraft.. The ASARS-2 radar was originally developed in the early 1980s by Hughes Aircraft, which was acquired by Raytheon in the late 1990s.
It was during this time he invented synthetic aperture radar in 1951, patented as "Pulsed Doppler Radar Methods and Means," #3,196,436. That same year Wiley posited the idea of solar sails in a science fiction story published in Astounding Science Fiction magazine entitled Clipper Ships of Space (originally titled Are the Clipper Ships gone ...
SAR is an abbreviation for synthetic-aperture radar, and "Lupe" is German for magnifying glass. The SAR-Lupe program consists of five identical (770 kg) satellites, developed by the German aeronautics company OHB-System, which are controlled by a ground station [1] responsible for controlling the system and analysing the retrieved data.

The NASA-ISRO Synthetic Aperture Radar (NISAR) mission is a joint project between NASA and ISRO to co-develop and launch a dual-frequency synthetic aperture radar on an Earth observation satellite in 2025. The satellite will be the first radar imaging satellite to use dual frequencies.
