In 1934 the British military began to make strides toward radar ( which also uses the magnetron ) under the direction of Dr Wimperis, culminating in the operation of the first radar station at Bawdsey in August 1936.

It has 14 scheduled monuments, ranging from the earliest signs of human activity to the remains of a World War II radar station.

During the Second World War, the Royal Air Force built a radar station on top of Ward Hill during the battle of the Atlantic.

Russia withdrew its troops by 31 August 1994, but maintained several hundred technical specialists to staff an OSCE-monitored phased-array ABM radar station at Skrunda until 31 August 1998.

On the way to Ramelle, Miller decides to take the opportunity to neutralize a small German machine gun position close to an abandoned radar station, despite the misgivings of his men.

A radar station called RAF Drytree was built during World War II.

Some object at the remote location echoes this PN signal back to the location station – either passively, as in some kinds of radar and sonar systems, or using an active transponder at the remote location, as in the Apollo Unified S-Band system.

Secondary radar overcomes these limitations but it depends on a transponder in the aircraft to respond to interrogations from the ground station to make the plane more visible.

* R V Jones, the Assistant Director Intelligence ( Science ) at the British Air Ministry insisted for reasons of tactical deception that for every radar station attacked within the real invasion area, two were to be attacked outside it.

Offensive INLA actions at this time included the 1982 bombing of the Mount Gabriel radar station in County Cork, which the INLA alleged was providing assistance to North Atlantic Treaty Organisation, allegedly in violation of Irish neutrality.

In the late 1970s, the Soviet Union began constructing a phased array radar station at Abalakova, near Krasnoyarsk, which violated the ABM Treaty.

Beginning in 1983, the United States demanded its removal, until the Soviet Union admitted the radar station was a violation in 1989.

A report written by Major-General Robert Laycock in 1947 said there was a German raid on a radar station on the Isle of Wight in 1941.

However, the rocket was exactly on courses and inaccurate readings had been picked up by a radar station 120 miles away.

It is famous due to the nearby RAF Neatishead radar station.

During World War II, a radar warning station and airfield were built near the railroad tracks ; a post office was established in 1948.

The station was decommissioned during the 1990s, and the radar dishes were dismantled sometime between 2004 and 2006.

During the 1950s, the United States Air Force established a base and radar station at Fort Yukon ; the town was officially incorporated in 1959.

Several hundred had plunged to their deaths according to the local television station KATV which also reported that its radar had shown a " large mass " over the town.

On 1 July 1956 Tyndall AFB became the station operating for the third phase of the ADC mobile radar program, being designated as TM-198.

The station flies a white radar aerostat, known locally as " Fat Albert ", which is used for drug interdiction missions by the Drug Enforcement Administration.

The airport is also the location of a National Weather Service radar station, Southeast River Forecast Center, and Weather Forecast Office, which serves 96 counties in northern and central Georgia.

The radar tower was at the summit and the cantonment of the station was at, about one mile ( 1. 6 km ) below the present base of the ski area on Radar Road.

Years ago this was true, but with the replacement of wires or runners by radio and radar ( and perhaps television ), these restrictions have disappeared and now again too much is heard.

Land-based radar would help with this task.

It was `` window '' -- the tinsel paper dropped by bombers to jam radar sets, to fill the scope with hundreds of blips that would seem to be approaching bombers.

They had ruined the radar warning system with their window, they had made themselves invisible above their flares.

As with all radar measurements, these rely on measuring the time taken for photons to be reflected from an object.

To help avoid collision with terrain ( CFIT ), aircraft use systems such as ground-proximity warning systems ( GPWS ), which use radar altimeters as a key element.

The limitations of beam-riding guidance ( which was slaved to an optical sight on single seater fighters and a radar with night fighters ) restricted the missile to attacks against targets flying a straight course and made it essentially useless against a maneuvering target.

As early as 1950 Douglas examined equipping the Sparrow with an active radar seeker, initially known as XAAM-N-2a Sparrow II, the original retroactively becoming Sparrow I.

Concurrently with the development of the Sparrow I, in 1951, Raytheon began work on the semi-active radar homing version of Sparrow family of missiles, the AAM-N-6 Sparrow III.

An upgraded version with active radar seeker, called Active Sky Flash was proposed by BAe and Thomson-CSF, but did not receive funding because the RAF opted for other missiles.

As with other semi-active radar guided missiles, the missile does not generate radar signals, but instead homes in on reflected continuous-wave signals from the launch platform's radar.

The launching aircraft will illuminate the target with its radar.

The AGM-88 can detect, attack and destroy a radar antenna or transmitter with minimal aircrew input.

It would work together with Westinghouse AN / APQ-81 radar.

Its weapons system, the AIM-54 working with the AWG-9 radar, migrated to the new U. S. Navy fighter project, the VFX, which would become the F-14 Tomcat.

The Tomcat's AWG-9 radar was capable of tracking up to 24 targets in Track-While-Scan mode, with the AWG-9 selecting up to six priority targets for potential launch by the AIM-54.

The upgrade is being carried out by Embraer and Elbit ; it includes a new avionics suite, a full glass cockpit with three MFDs, HOTAS configuration and a new multimode radar, the Italian Grifo F. The first F-5EM was handed over on September 21, 2005, and it is scheduled at a rate of two aircraft being delivered each month from that date onwards.

Instead, this effort evolved into the SAGE system for the US Air Force, which used large screens and light guns to allow operators to interact with radar data stored in the computer.

They were fitted with new anti-aircraft guns, radar, and forward-launched ASW weapons, in addition to their existing light guns, depth charges, and torpedoes.

Neither of the Air Force fighter pilots saw anything exit the airliner, either visually or on radar, nor did they see a parachute open ; but at night, with extremely limited visibility and cloud cover obscuring any ground lighting below, an airborne human figure clad entirely in black clothing could easily have gone undetected.

Signal Processing is a very mathematically oriented and intensive area forming the core of digital signal processing and it is rapidly expanding with new applications in every field of electrical engineering such as communications, control, radar, TV / Audio / Video engineering, power electronics and bio-medical engineering as many already existing analog systems are replaced with their digital counterparts.
