	FAA - Airport Surveillance Radar (ASR-11)
		The primary surveillance radar uses a continually rotating antenna mounted on a tower to transmit electromagnetic waves that reflect, or backscatter, from the surface of aircraft up to 60 miles from the radar.
		The secondary radar uses a second radar antenna attached to the top of the primary radar antenna to transmit and receive area aircraft data for barometric altitude, identification code, and emergency conditions.
		The secondary radar operates in the range of 1030 to 1090 MHz.

	Radar Theory
		The first, called the Primary Surveillance Radar, operates on the principle of sending a narrow beam of energy, which is reflected from the aircraft under surveillance, and measuring its distance by noting the time lapse between the radar pulse transmission and its received echo.
		The Radar station at Piduruthalagala(Sri Lanka), the PSR and SSR antennas are co-located and scan synchronized, and both radars are used in conjunction to develop the total air traffic situation display on a single CRT radar scope, called the Plan Position Indicator (PPI).

	Primary and Secondary Radar
		The orientation of the radar antenna provides the bearing of the aircraft from the ground station, and the time taken for the pulse to reach the target and return provides a measure of the distance of the target from the ground station.
		When PSR was the only type of radar available, this was typically achieved by the Controller observing a directed turn by the aircraft, or by correlating a DME distance report by the aircraft with the position of a particular return along a known track.
		Radar data was displayed to controllers on the 'bright display' system which could be viewed in a dimly lit environment.

	ATCMonitor.com - AIR TRAFFIC CONTROL RADAR - HOW IT WORKS AND WHERE IT'S HEADED
		This early radar method was known as continuous wave radar, because the signal from the radar equipment was one continuous signal projected onto the target, which would only provide ATC with the knowledge that there was a target, but no information about the aircraft type, or its position, speed or altitude.
		For instance, the Airfield Surface Detection Equipment (ASDE) provides radar surveillance of aircraft and airport surface vehicles at high activity airports (Atlanta's ASDE is shown on top of the Atlanta tower in the picture to the right).

	Radar Basics
		The transmitted high-frequency impulses are reflected by the target and then received by the same radar unit.
		Secondary radar units work according to another principle: These work with active answer signals.
		Because the transmit power influences the radar equation at the primary radar with the two way travel, at the secondary surveillance radar only one way.

	BBC - h2g2 - Primary and Secondary Radar - A588684
		Radar development may have been driven by military needs, but it is now used widely in civilian application for the detection of ships and aircraft.
		Primary radar is a pulsed beam of ultrahigh frequency radio waves 'shone' in a circle from a rotating aerial.
		Range and direction can be determined from the SSR signal in much the same way as with primary radar, measuring the time between sending the interrogation and receiving the reply, making allowance for the turn-round delay in the transponder.

	EUROCONTROL - Primary Radar Surveillance
		Nevertheless, it is expected that non-cooperative independent surveillance in the form of Primary Surveillance Radar (PSR) within approach and TMA airspace remains a standing requirement.
		For en-route surveillance the situation is different as the principal technical solution remains dual SSR coverage not supplemented by PSR.
		To enable this, there may be a requirement to supplement secondary surveillance radar information with active or passive sensor information.
