How does fire control radar work?
The fire-control radar switches to the acquisition phase of operation once the radar is in the general vicinity of the target. The fire-control radar enters into the track phase when the target is located. The radar system locks onto the target during this phase. This phase ends when the target is destroyed.
Does Apache have radar?
The Apache Longbow has a distinctive radar dome mounted to its mast. One of the coolest things about the Apache is its sophisticated sensor equipment. The Longbow Apache detects surrounding ground forces, aircraft and buildings using a radar dome mounted to the mast.
What is radar frequency interferometer?
The Modernized Radar Frequency Interferometer system identifies intelligence, surveillance and reconnaissance (ISR) emitters and allows the pilot to detect and engage a threat long before the aircraft becomes vulnerable, increasing aircraft survivability and lethality.
Were Apache helicopters used in Vietnam?
But the Army’s Apache attack helicopter aviators they had struck first to “kick down the door” for the Nighthawks. Helicopter gunships had proven highly useful in Vietnam for delivering precise strikes and loitering air support—but relatively lightly-armed Viet Cong had shot down hundreds of them.
How many Chinook helicopters are there in the US?
750 Chinook helicopters
Of the nearly 750 Chinook helicopters in the U.S. and South Vietnam fleets, about 200 were lost in combat or wartime operational accidents. The U.S. Army CH-47s supported the 1st Australian Task Force as required. Four CH-47s were converted into ACH-47As by adding armor and improved engines.
What is tracking radar system?
The Radar, which is used to track the path of one or more targets is known as Tracking Radar. In general, it performs the following functions before it starts the tracking activity. Target detection. Range of the target. Finding elevation and azimuth angles.
What does APR 39 stand for?
Radar Warning Receiver
The AN/APR-39 Digital Threat Warning System monitors the environment for pulsed radar signals, characterize and identify them, and alert the crew to the existence of emitters.
What is radar baseline?
The distance between the two antenna positions (the so-called baseline) is a multiplier for the phase difference. The baseline should not be too large so that the reflection conditions between the two measurements do not change.
What does APG-78 FCR stand for?
Developed and fielded for the AH-64D Apache, the APG-78 LONGBOW Fire Control Radar (FCR) is a combat proven force multiplier. LONGBOW FCR has repeatedly demonstrated its operational capabilities to dramatically increase Apache’s mission success.
What kind of radar does the AH-64D Apache Longbow have?
The AH-64D Apache Longbow is equipped with a glass cockpit and advanced sensors, the most noticeable of which being the AN/APG-78 Longbow millimeter-wave fire-control radar (FCR) target acquisition system and the Radar Frequency Interferometer (RFI), housed in a dome located above the main rotor.
What is the Longbow radar?
The LONGBOW radome, mounted atop the AH-64 Apache attack helicopter main rotor, is just visible poking above terrain behind which the Apache hovers. Because of the LONGBOW radar’s mounting location, the Apache can acquire and track targets without being detected. (Photo by Lockheed Martin)
Does the British Army still use the Apache Longbow?
The UK currently operates a modified version of the Apache Longbow; initially called the Westland WAH-64 Apache, it is designated the Apache AH1 by the British Army. Westland built 67 WAH-64 Apaches under license from Boeing, following a competition between the Eurocopter Tiger and the Apache for the British Army’s new Attack…
