AN/APG-63. The AN/APG-63 and AN/APG-70 are a family of all-weather multimode radar systems designed by Hughes Aircraft (later Raytheon) for the F-15 Eagle air superiority fighter. These X band pulse-Doppler radar systems are designed for both air-air and air-ground missions; they are able to look up at high-flying targets and down at low-flying ...
The observation network was significantly expanded in 2009 with automated weather stations, [4] and the Doppler weather radar was upgraded the next year to have a range of 480 km (300 mi). [3] The Centre for Climate Research Singapore (CCRS) was established in 2013, with its purpose to research tropical climates using computer models. [7]
A NEXRAD weather radar currently used by the National Weather Service (NWS) is a 10 cm wavelength (2700-3000 MHz) radar capable of a complete scan every 4.5 to 10 minutes, depending on the number of angles scanned, and depending on whether or not MESO-SAILS is active, which adds a supplemental low-level scan while completing a volume scan. Its ...

0-70°. Herakles is a passive electronically scanned array multi-function radar manufactured by Thales Group. It is installed on board the FREMM multipurpose frigates and the Formidable-class frigates of the Republic of Singapore Navy . It has a track capacity of 400 [ 2] air and surface targets and is able to achieve automatic target detection ...
[1] The resolution of any radar depends on the width of the beam and the range to the target. For example; a radar with 1 degree beam width and a target at 120 km (75 mi) range will show the target as 2 km (1.2 mi) wide. To produce a 1-degree beam at the most common frequencies, an antenna 1.5 kilometres (0.93 mi) wide is required.
Radar beacon. Racon signal as seen on a radar screen. This beacon receives using sidelobe suppression and transmits the letter "Q" in Morse code near Boston Harbor (Nahant) 17 January 1985. Radar beacon (short: racon) is – according to article 1.103 of the International Telecommunication Union's (ITU) ITU Radio Regulations (RR) [1 ...
