This is an incomplete list of ground-based radars operated by the United States Marine Corps since the service first started utilizing radars in 1940. [1] The Marine Corps' has used ground-based radars for anti-aircraft artillery fire control, long range early warning, Ground-controlled interception (GCI), ground directed bombing, counter-battery radar, short-range cueing for man-portable air ...
The AN/CPS-1, also known as the Microwave Early Warning (MEW) radar, was a semi-mobile, S band, early-warning radar developed by the MIT Radiation Laboratory during World War II. It was one of the first projects attempted by the Lab and was intended to build equipment to transition from the British long-wave radar to the new microwave ...
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.
It is different from passive remote sensing, the most common type, as the electromagnetic radiation (EMR) is produced by the emitters and they transmit radiation at radio wavelengths (i.e. from around 1 cm to several meters) and sensors use the measured return to infer properties of the Earth's surface. radar remote sensing uses long-wavelength ...
This radar is an acknowledged derivative of the Israeli EL/M-2080 Green Pine long range radar, which is the critical component of that country's Arrow missile defense system. [3] However, it differs from the Israeli system as it employs Indian Transmit Receive modules, signal processing, computers and power supplies.
The European Space Agency's Planck satellite has been gathering data since its launch in 2009, slowly building up a map of the cosmic microwave background radiation -- a distant remnant of the Big ...
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
The radar footprint (the size of the surface area which is illuminated by the radar) must be small in comparison with all ocean wavelengths of interest. The radar spatial resolution is determined by the bandwidth of the radar signal (see radar signal characteristics) and the beamwidth of the radar antenna. The beam of a microwave antenna diverges.
