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 ...
ALTAIR (ARPA Long-Range Tracking And Instrumentation Radar) is a radar tracking station on Roi-Namur island in the north part of the Kwajalein atoll in the Marshall Islands. It is a high-sensitivity, wide-bandwidth, coherent, instrumentation and tracking radar that is capable of collecting precise measurements on small targets at long-ranges.
The radar was upgraded with a completely new antenna capable of dual-band operations, called Haystack Ultrawideband Satellite Imaging Radar (HUSIR). The system is capable of simultaneous operations in X band and W-band , which allows it to better determine the size, shape, orientation, and motion of orbiting objects. [ 11 ]
SARs produce a two-dimensional (2-D) image. One dimension in the image is called range and is a measure of the "line-of-sight" distance from the radar to the object. Range is determined by measuring the time from transmission of a pulse to receiving the echo from a target. Also, range resolution is determined by the transmitted pulse width.

S1850M radar on HMS Daring. The S1850M is a long-range radar with a digital antenna array for wide area search in elevation. The S1850M is manufactured by Thales and BAE Systems Integrated System Technologies (formerly AMS UK). It is a modified version of the Thales Nederland SMART-L radar. The S1850M is advertised as being capable of fully ...

Microwave wavelengths in the centimeter range were required to give the small radar antennas which were compact enough to fit on aircraft a narrow enough beamwidth to localize enemy aircraft. It was found that conventional transmission lines used to carry radio waves had excessive power losses at microwave frequencies, and George Southworth at ...
