National Radar Cross Section Test Facility; The National Radar Cross Section Test Facility (NRTF) is the DoD facility for RCS testing. Formerly known as RATSCAT, which began measuring radar scattering in 1963, it comprises two complementary sites, Main site and RATSCAT Advanced Measurement System (RAMS).
Radar cross-section (RCS), denoted σ, also called radar signature, is a measure of how detectable an object is by radar. A larger RCS indicates that an object is more easily detected. A larger RCS indicates that an object is more easily detected.
The United States' National Radar Cross-section Facility (commonly abbreviated as RATSCAT) is located at Holloman AFB, New Mexico. The Lockheed Have Blue and Lockheed F-117 Nighthawk have been tested at this site.
The AN/APG-77 system itself exhibits a very low radar cross-section, supporting the F-22's stealthy design. [3] The upgraded APG-77(V)1 may have an even greater range. Much of the technology developed for the APG-77 was used in the AN/APG-81 radar for the F-35 Lightning II , and in turn the technology from the APG-81 was applied to the upgraded ...
Giraffe is designed to detect low-altitude, low cross-section aircraft targets in conditions of severe clutter and electronic countermeasures. When equipped as an air-defense command center, Giraffe provides an air picture to each firing battery, using man portable radio communication.
The RR-144 is designed to prevent interference with civil ATC radar systems. Chaff, originally called Window [1] or Düppel, is a radar countermeasure involving the dispersal of thin strips of aluminium, metallized glass fiber, or plastic. [2] Dispersed chaff produces a large radar cross section intended to blind or disrupt radar systems. [3]
The GEM-T was given a new fuze which was further optimized against ballistic missiles and a new low noise oscillator which increases the seeker's sensitivity to low radar cross-section targets. The GEM-C is the upgraded version of the GEM, and the GEM-T is the upgraded version of the PAC-2. The GEM+ entered service in November 2002. [28]
Radar engineering is the design of technical aspects pertaining to the components of a radar and their ability to detect the return energy from moving scatterers — determining an object's position or obstruction in the environment.
