Merrill Skolnik (November 6, 1927 – January 27, 2022) was an American researcher in the area of radar systems and the author or editor of a number of standard texts in the field. He is best known for his introductory text "Introduction to Radar Systems" and for editing the "Radar Handbook".
On December 15, 2000, the FPS-50 and −92 transmissions ceased [citation needed] (all of the Arecibo Observatory's Litton L-5773 klystrons were obtained as surplus from Clear's decommissioned BMEWS transmitters.) [29] Clear's FPS-120 began 24-hour operations [citation needed] when Clear's SSPARS Site (separate from the BMEWS site) had Initial ...
And for the same examples : the radar horizon for the radar at a 1-mile (1.6 km) altitude will be 102-mile (164 km) and the one at 75 feet (23 m) will be 12-mile (19 km). Furthermore, layers with an inverse trend of temperature or humidity cause atmospheric ducting , which bends the beam downward or even traps radio waves so that they do not ...
Transposed Block Face-splitting product in the model of a Multi-Face radar with DAA, proposed by V. Slyusar in 1996 [5]. The main approach to digital signal processing in DAA is the "digital beamforming" after Analog-to-digital converters (ADC) of receiver channels or before Digital-to-analog converters (DAC) by transmission.
Radar range and wavelength can be adapted for different surveys of bird and insect migration and daily habits. They can have other uses too in the biological field.

The Duga radar is heavily featured in the virtual reality game Proze: Enlightenment, a suspense/puzzle game with the theory that the radar is being used by mind controlling experiments during the 1950-60s. The game actually starts with the player ascending one of the pylons on a maintenance lift.
The Ballistic Missile Early Warning System (BMEWS) was a radar system built by the United States (with the cooperation of Canada and Denmark on whose territory some of the radars were sited) during the Cold War to give early warning of a Soviet intercontinental ballistic missile (ICBM) nuclear strike, to allow time for US bombers to get off the ground and land-based US ICBMs to be launched, to ...
The Zaslon is a pulse-Doppler radar with a passive electronically scanned array (PESA) antenna and digital signal processing. The antenna used by the Zaslon is actually a multi-channel system comprising two separate electronically controlled arrays, an X band radar with 1700 emitters and a L band transponder with 64 emitters brought together into a single antenna.
