	Fire-control radar - Definition, explanation
		A fire-control radar is a radar which is designed specifically to provide information (mainly target azimuth, elevation, range and velocity) to a fire-control system in order to calculate a firing solution (i.e.
		This works either by having the radar switch between sweeping the search sector and sending directed pulses at the target to be tracked, or by using a phased-array antenna to generate two (or more) discrete radar beams and dividing them between both tasks.
		Radar resolution is the ability of the radar to differentiate between two targets closely located.

	ACTIVE AND SEMIACTIVE RADAR MISSILE GUIDANCE (Site not responding. Last check: 2007-10-29)
		The source of the reflected radiation is a radar transmitter; in the instance of weapons with active radar guidance, this transmitter is situated within the missile; in the case of semiactive guidance, it is carried by the launch aircraft.
		Surveillance radars usually employ fairly wide beams, the objective being the detection of the target, tracking beams, on the other hand, must be very narrow, as they serve to accurately measure the position of the target with respect to the radar.
		In the mid-fifties, when it was decided to develop radar guidance for air-air missiles, it was impossible, with state of the art technology, to package a radar transmitter and receiver of the appropriate range into a medium sized missile.

	Radar Basics (Site not responding. Last check: 2007-10-29)
		The maximum range ability of surface-search radar is primarily limited by the radar horizon; therefore, higher frequencies are used to permit maximum reflection from small, reflecting areas, such as ship masthead structures and the periscopes of submarines.
		In the case of aircraft control, the guidance information is obtained by the radar operator and passed to the aircraft by either voice radio or a computer link to the aircraft.
		The primary function of a height-finding radar (sometimes referred to as a three-coordinate or 3D radar) is that of computing accurate ranges, bearings, and altitudes of aircraft targets detected by air-search radars.

	Camouflage and Radar
		Camouflage and radar are complex subjects of study, radar particularly as it is a dynamic system that depends on a skillful operator and appreciative commander for maximum effect.
		Fire (as in "gun fire") control radar was optimized to detect and track specific targets, forming a critical input to fire direction systems.
		Fire control directors solved the complex problem of aiming a weapon based on the target's range, speed and direction and the ship's own movement (including roll).

	Radar
		Because a radar antenna may both transmit and receive signals, the duplexer determines whether the antenna is connected to the receiver or the transmitter.
		The PPI displays the direction of the target in relation to the radar system (relative to north)as an angle measured from the top of the display, while the distance to the target is represented as a distance from the center of the display.
		Simple pulse radar requires precise timing circuits in the duplexer to prevent the transmitter from transmitting while the receiver is acquiring a signal from the antenna, and to keep the receiver from trying to read a signal from the antenna while the transmitter is operating.

	Best Battleship: Fire Control
		And the radar used by Washington off of Guadalcanal was not as good as the sets fitted aboard Iowa.
		Radar operating at meter or decimeter wavelengths is useful for ranging, but lacks the angular accuracy necessary for training.
		This hybrid fire-control solution is, of course, limited by the quality of the optics available, and also by the visual horizon (which is closer than the radar horizon), and weather conditions.

	Performance of US Battleships at Surigao Strait
		That the Mark 8 Fire Control Radar (FCR) was superior to the Mark 3 FCR is neither a mystery, in contention, nor a surprise.
		Maryland probably held a solid radar target for the next three to five minutes and then probably lost the target briefly (0404-0405?) in her turn to 270 as the superstructure masked the Mark 3 radar on the after director and it slewed around to reacquire on a port bearing.
		Between 0355 and 0359, the Yamashiro was probably badly obscured on radar due to the profusion of shell splashes as a result of the fire from West Virginia, Tennessee and California.
