The history of synthetic-aperture radar begins in 1951, with the invention of the technology by mathematician Carl A. Wiley, and its development in the following decade. Initially developed for military use, the technology has since been applied in the field of planetary science .
The most widespread radar device today is undoubtedly the radar gun. This is a small, usually hand-held, Doppler radar that is used to detect the speed of objects, especially trucks and automobiles in regulating traffic, as well as pitched baseballs, runners, or other moving objects in sports.
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 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.
In 1944, the US Army contracted [7] for an electronic "computer with guns, a tracking radar, plotting boards and communications equipment" (M33C & M33D models used different subassemblies for 90 & 120 mm gun/ammunition ballistics.) [3] The "trial model predecessor" (T-33) was used as late as 1953, [8] and the production M33 (each $383,000 in 1954 dollars) [9] had been deployed in 1950. [10]

To expedite the test, a synthetic-aperture radar designed for airborne use was adapted, by subcontractor Goodyear, to space operation and the long ranges involved, based on criteria developed by the research team at another participating organization whose relationship to Quill has not yet been declassified.
