KMOV (channel 4) is a television station in St. Louis, Missouri, United States, affiliated with CBS. It is owned by Gray Television alongside low-power station KDTL-LD (channel 4.6). The two stations share studios on Progress Parkway in suburban Maryland Heights ; KMOV's transmitter is located in Lemay, Missouri .
Doppler effect. The emitted signal toward the car is reflected back with a variation of frequency that depends on the speed away/toward the radar (160 km/h). This is only a component of the real speed (170 km/h). The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842, is the difference ...
Kamov Ka-27. The Kamov Ka-31 ( NATO reporting name Helix) is a military helicopter originally developed for the Soviet Navy and currently in service in Russia, China, and India in the naval airborne early warning and control role. As with all Kamov helicopters except the Ka-60 /-62 family, the Ka-31 has co-axially mounted contra-rotating main ...
Continuous-wave radar ( CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. [1] Individual objects can be detected using the Doppler effect, which causes the received signal to have a different frequency from the transmitted signal ...
The pulse width ( ) (or pulse duration) of the transmitted signal is the time, typically in microseconds, each pulse lasts. If the pulse is not a perfect square wave, the time is typically measured between the 50% power levels of the rising and falling edges of the pulse. The pulse width must be long enough to ensure that the radar emits ...
AN/SPS-64 Navigation radar, a surface navigation and search radar, made by Raytheon and used both commercially (brand name Mariner's Pathfinder) and by navies worldwide. [ citation needed ] AN/SPS-65 Development of AN/SPS-58 by Westinghouse as a low altitude radar that is part of the Mark 91 Fire Control System for the Sea Sparrow air defense ...
Radar is a system that uses radio waves to determine the distance ( ranging ), 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.
