2. Phoenix (ATC) - Wikipedia

   en.wikipedia.org/wiki/Phoenix_(ATC)

   PHOENIX is a multipurpose Radar Data Processing System(RDPS) / Surveillance Data Processing System (SDPS) - a.k.a. tracker - used for many ATC applications in the Deutsche Flugsicherung (DFS), and is continuously extended and maintained ever since.

3. Synthetic-aperture radar - Wikipedia

   en.wikipedia.org/wiki/Synthetic-aperture_radar

   Before rapid digital computers were available, the data processing was done using an optical holography technique. The analog radar data were recorded as a holographic interference pattern on photographic film at a scale permitting the film to preserve the signal bandwidths (for example, 1:1,000,000 for a radar using a 0.6-meter wavelength).

4. Space-time adaptive processing - Wikipedia

   en.wikipedia.org/wiki/Space-time_adaptive_processing

   Space-time adaptive processing (STAP) is a signal processing technique most commonly used in radar systems. It involves adaptive array processing algorithms to aid in target detection. Radar signal processing benefits from STAP in areas where interference is a problem (i.e. ground clutter, jamming, etc.). Through careful application of STAP, it ...

5. Interferometric synthetic-aperture radar - Wikipedia

   en.wikipedia.org/wiki/Interferometric_synthetic...

   The processing chain used to produce interferograms varies according to the software used and the precise application but will usually include some combination of the following steps. Two SAR images are required to produce an interferogram; these may be obtained pre-processed, or produced from raw data by the user prior to InSAR processing.

6. Radar - Wikipedia

   en.wikipedia.org/wiki/Radar

   Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.

7. Ground-penetrating radar - Wikipedia

   en.wikipedia.org/wiki/Ground-penetrating_radar

   Ground-penetrating radar uses a variety of technologies to generate the radar signal: these are impulse, [48] stepped frequency, frequency-modulated continuous-wave , and noise. Systems on the market in 2009 also use Digital signal processing (DSP) to process the data during survey work rather than off-line.
