Can helicopters be detected by radar?

Can helicopters be detected by radar?

Since a helicopter can fly at a very small altitude, it may fail to be detected by classical rotating surveillance radars. Besides, because of low speed, its echo may be filtered out in the course of processing radar signals, along with removal of constant echoes.

Can a helicopter defeat a fighter jet?

‘A well equipped attack helicopter flown by a trained crew will defeat most fighter airplanes in 1v1 air combat, should the fighter be foolish enough to drop down to try and engage,’ Nick Lappos, Technical Fellow Emeritus at Sikorsky and former U.S. Army AH-1 Cobra attack helicopter pilot, said on Quora.

Has an attack helicopter shot down a jet?

A helicopter shooting down a fighter aircraft, happen only during the 1980–1988 Iran/Iraq war. The Bell AH-1J Super cobra Helicopter, working with the Islamic Republic of Iran armed forces, was the most successful helicopter in the War, (like the other weapons on Iranian disposal at that time.

Who invented radar ww2?

Sir Robert Watson-Watt
One of the greatest radar pioneers was Sir Robert Watson-Watt, who developed the first practical radar system that helped defend the British in WWII.

How are radars made?

A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the object(s).

How do radars detect missiles?

The ground-based radars would constantly send pulses of high-frequency radio waves toward the horizon; if a missile was launched, the radio waves would be reflected off the missile back to the radar antenna, while the satellites would search for heat signatures from the missiles.

What are the units of radar cross section?

The units of radar cross section are square meters; however, the radar cross section is NOT the same as the area of the target. Because of the wide range of amplitudes typically encountered on a target, RCS is frequently expressed in dBsm, or decibels relative to one square meter.

What determines the total RCS of a radar platform?

In some cases, the onboard sensors can be the predominant factor in determining a platform’s total RCS. A typical example is a reciprocal high gain antenna on a low RCS platform. If the antenna beam is pointed toward the radarand the radar frequency is in the antenna operating band, theantenna scattering can be significant.

What happens to a radar cross section at a discontinuity?

Upon reaching a surface discontinuity, for example an edge, the traveling wave is scattered and part of it propagates back toward the radar. The sum of the traveling waves propagating from the far end of the target toward the near end is the dominant source to the target radar cross section.

What is the difference between the F-35 and the F/A-22?

“From the front, the F/A-22’s signature is -40dBm2 (the size of a marble) while the F-35’s is -30 dBm2 (the size of a golf ball). The F-35 is said to have a small area of vulnerability from the rear because engineers reduced cost by not designing a radar blocker for the engine exhaust.”
