From February 1943 the US used a universal system to identify radar variants, consisting of three letters and a number, respectively designating platform, type of equipment, function, and version. Reduced 4-foot (1.2 m) antennas in aerial outfit AUS. First fitted to Decimetric (50 cm) ranging set for Bofors 40 mm and "multiple pom-pom" fire control. Type 285P with five element Yagi antenna with combined Tx / Rx function. Had separate Tx and Rx antennas, combined in Type 279M to single antenna operation. The Type 285M could provide accurate ranges via the mechanical ranging panel, L12, and bearing information using lobe switching, but height finding was primitive and had to be calculated using maximum signal indication. Became Operational : First fitted to corvette HMS Orchis in May 1941. The antennas were mounted on a stabilized mounting and placed high on the mast on cruiser and battleship sized ships. Type 280 radar; Type 281 radar; Type 282 radar; Type 283 radar; Type 284 radar; Type 285 radar; Type 286 radar; Type 290 radar; Type 291 radar; Type 293 radar; Type 965 radar; Type 1007 radar; Type 1022 radar; Type 2007 radar; SharpEye™ solid state radar; SCV radar; Airborne Edit. First British ship-based radar system. This radar used a frequency of 90 MHz, a beamwidth of 35°, and a wavelength of 3.5 metres. Type 271. Was not considered successful and not widely used. Main armament ranging and shot-spotting set for Combined the electronics of the Type 277 and the stabilized mounting of the Type 273. Used a single transmit/receive antenna, Follow on from Type 79, metric air warning set. Original Type 291 had a hand-steered antenna, replaced by Type 291M with power training and plan position indicator. This system was continued after WWII with multiservice designations being prefixed by 'AN/' for Army-Navy. This set also had a secondary surface search with surface and aerial gunnery capability and used a Precision Ranging Panel, which passed accurate radar ranges directly to the Metric air warning set with separate Tx / Rx antennas. The first successful airborne microwave radar. Became Operational: … Used on Navy Swordfish and Air warning set for submarines replacing Type 291W.A version of the Type 271 with a cable-drive and more powerful receiver allowing the antenna to be mounted remotely from the radar office. Multi-service classification codes according to the Polmar, Norman (December 1978). Fitted to HMS Sheffield. The PRP allowed for accurate range determination, range rate determination using radar, and accurate transmission of radar ranges and range rates to The Type 282, 282M, 285, and 285M radars used a mechanical ranging panel that used a mechanical cursor placed over the ranging display, to estimate range and automatically transmitted the calculated range to either the War Status: Used operationally in war on small ships: Purpose: Surface Warning: Wavelength: 10 cm: Power Output: 5 - 90 KW: Range: 10 - 25: First microwave radar set. Basic users (becoming a basic user is free and easy!) the metric Type 284 was replaced by the centimetric Type 274). view 40 history. United States Naval Institute Proceedings. In the Centimetric replacement for Type 284. Type 281B had combined Tx / Rx antenna. Originally known as Type 271 Mark V, this was a significant upgrade of the original design and was later renamed to make this clear. Metric sets were numbered in the 28x and 29x series.
The larger antennas more than made up for the wiring losses seen in the 272, and the resulting system was even more powerful than the original 271. When centimetric sets arrived with the advent of the cavity magnetron, they were numbered by subtracting 10 from the metric type number they were based on (e.g. The shutdown option can be used for intermittent operation in battery powered applications. IPS-280 High sensitivity K-Band CW Doppler Radar with adjustable frequency and I Q - outputs. Type 272. This set used a Precision Ranging Panel and was used to fire the guns automatically using the Main armament ranging and shot-spotting set for cruisers and battleships with Ranging set for anti-aircraft fire control, fitted to HACS directors and rangefinder-directors and used ranging panel L12. View photos of G280. U and W variants for coastal craft and submarines respectively.Based on the same electronics as the Type 277/276, the The Precision Ranging Panel (PRP) was an electromechanical transmission and calculating system. "The U.S.Navy: Sonars, Part 1". These sets were initially numbered as wireless telegraph (w/t) sets, but a distinguishing prefix of "2" was soon added. "The U.S.Navy: Shipboard Radars". This was not always possible however, as Types 271 - 274 were already in use for original centimetric sets, thus some metri… Fitted on Bofors mounting Mark IV "Hazemeyer" and Main armament anti-aircraft barrage fire control set fitted to "barrage director" for cruiser 6-inch (150 mm) and battleship guns.
