Mark 37 Director c1944 with Mark 12 (rectangular antenna) and Mark 22 "orange peel" Ship gun fire-control systems (GFCS) are analogue fire-control systems that were used aboard naval warships prior to modern electronic computerized systems, to control targeting of guns against surface ships, aircraft, and shore targets, with either optical or radar sighting.
An early radar detector Car radar detector (Japanese) A radar detector is an electronic device used by motorists to detect if their speed is being monitored by police or law enforcement using a radar gun. Most radar detectors are used so the driver can reduce the car's speed before being ticketed for speeding.
The Integrated Helmet and Display Sight System (IHADSS) 30 mm M230 chain gun turret on a Boeing AH-64 Apache being aimed with a helmet-mounted sight A helmet-mounted display (HMD) is a headworn device that uses displays and optics to project imagery and/or symbology to the eyes.
A line-replaceable unit (LRU [1]), lower line-replaceable unit (LLRU), [citation needed] line-replaceable component (LRC), or line-replaceable item (LRI) [2] is a modular component of an airplane, [3] ship or spacecraft [4] (or any other manufactured device) that is designed to be replaced quickly at an operating location (1st line).
Construction began at an upper location [need quotation to verify] of the former World War II Mount Tamalpais Radar Site of the Aircraft Warning Service [5] (the World War II information center of the AWC was located at tbd for plotting radar tracks in the San Francisco area).
When the unit activated, it could only be switched off by inserting this key. Current applications integrate the PASS device into the SCBA worn by firefighters so that it automatically arms when the SCBA air supply is engaged or when the SCBA is removed from its mounting bracket.
Pulse-Doppler radar sensors are therefore more suited for long-range detection, while FMCW radar sensors are more suited for short-range detection. Monopulse : A monopulse feed network, as shown in Fig. 2, increases the angular accuracy to a fraction of the beamwidth by comparing echoes, which originate from a single radiated pulse and which ...
Post-war models added a small radar to automate the range measurement; these are known as radar gunsights. Gyro sights usually contained more than one reticle to assist in proper aiming: a fixed one, often just a dot, signifying the direction the guns are pointing, a moving one showing the corrected aiming point, and a ring to match to a target ...
