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".
As the delays grew, the Mk. 4 was put back into full development, and the first prototypes began to arrive in 1944, just as the supply of the SCR-584 improved. Development was once again curtailed. This all proved to be lucky timing, as the arrival of production SCR-584s was coincident with the start of the V-1 flying bomb campaign that summer.
The radar mile is the time it takes for a radar pulse to travel one nautical mile, reflect off a target, and return to the radar antenna. Since a nautical mile is defined as 1,852 m, then dividing this distance by the speed of light (299,792,458 m/s), and then multiplying the result by 2 yields a result of 12.36 μs in duration.
Monostatic monopulse-Doppler radar sensors offer advantages over FMCW radars, such as: Half-duplex: Pulse-Doppler radar sensors are half-duplex, while FMCW radar sensors are full-duplex. Hence, pulse-Doppler provide higher isolation between transmitter and receiver, increasing the receiver's dynamic range (DR) and the range detection considerably.
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 ...
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 ...
An ionosonde, or chirpsounder, is a special radar for the examination of the ionosphere. The basic ionosonde technology was invented in 1925 by Gregory Breit and Merle A. Tuve [ 1 ] and further developed in the late 1920s by a number of prominent physicists, including Edward Victor Appleton .
The chirp pulse compression process transforms a long duration frequency-coded pulse into a narrow pulse of greatly increased amplitude. It is a technique used in radar and sonar systems because it is a method whereby a narrow pulse with high peak power can be derived from a long duration pulse with low peak power.
