CATR is a State Department bureau that oversees export controls on dual-use technologies and conventional weapons. It also participates in the Wassenaar Arrangement and interdicts the diversion of sensitive components and technology.
The F9650A Compact Antenna Test Range (CATR) is a platform for wireless and antenna system performance characterization at millimeter-wave frequencies. It supports 5G NR RF design verification, conformance, RRM, AoA, demodulation and carrier acceptance test with various options and upgrades.
A Compact Antenna Test Range (CATR) allows electrically large antennas to be measured at a significantly shorter distance than would be necessary in a traditional far-field test range. Compact ranges use a source antenna (feed) to radiate a spherical wave in the direction of a parabolic reflector, collimating it into a planar wave for aperture illumination of a Device under Test (DUT). Its ...
CATR is responsible for U.S. policy on conventional weapons and related dual-use technology, export controls, interdictions, sanctions, and commercial remote sensing satellites. It leads U.S. delegations to the Wassenaar Arrangement and participates in the Arms Trade Treaty and the U.N. Register of Conventional Arms.
CATRA has offered an opportunity for Capital Area residents from all generations with all types of special and typical needs to establish an atmosphere of support, respect, and health. We come together in an equestrian farm enviroment offering a therapeutic riding experience to those able to benefit from it.
ISN/CATR leads USG efforts to curb the proliferation of advanced conventional weapons and related dual-use technology. It coordinates US policy on export controls, transparency, interdictions, sanctions, and commercial remote sensing satellites.
CATR was established with the vision of providing transformative learning experiences to students globally. CATR has been duly registered with the Government and has achieved ISO certification. CATR is established as a distinguished digital platform for educational purposes and career progression, providing individuals across the globe with the chance to participate in online and offline ...
A Compact Antenna Test Range (CATR) is a type of range used for antenna testing at frequencies where the far-field spacing would be impractical for traditional outdoor or free space methods. A CATR uses one or more parabolic reflectors to collimate spherical waves of a source, or feed, antenna into planar waves within the desired test zone where the antenna under test is placed. This test zone ...
A Compact Range System or Compact Antenna Test Range (CATR) makes direct far-field measurements of electrically large antennas in a shielded anechoic chamber. It uses a large parabolic reflector to project a small radiating source (feed) into the far field. The reflector is used to transform a spherical wave into a plane wave with far-field characteristics. Multiple-feed systems may be used to ...
Learn about the two anechoic chambers at ESA that simulate space conditions for antenna testing: the Compact Antenna Test Range (CATR) and the Hybrid Environment for Radio Frequency Testing (HERTZ). Find out their features, sizes, frequencies, and applications for satellite antennas and payloads.
