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".
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 .
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.
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.
Coverage of the original PAVE PAWS and BMEWS systems, later upgraded to SSPARS and eventually to UEWR BMEWS solid-state phased-array radar at RAF Fylingdales. The Solid State Phased Array Radar System [1] (SSPARS), colloquially Ballistic Missile Early Warning System radar network (BMEWS radar network), [2] is a United States Space Force radar, computer, and communications system for missile ...
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.
A Duga radar is featured in the 2021 video game Chernobylite. [22] In episode 12 of the first season of the NBC science fiction series Debris, the Duga radar array makes an appearance as a fictional array in the state of Virginia. The Chernobyl Duga site is featured in the Science Channel series "Mysteries of the Abandoned" (season 1, episode 1 ...
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 ...
