aircraft detection

As the war grew closer, the need for an aircraft detection was critical.

Just what you'd need for an echo-principle aircraft detection system."

Aircraft detection radar experimentally introduced in 1941, widely fitted from March 1943.

The submarine's regular radar will have to be tweaked up for long-range aircraft detection.

At the beginning of 1953, the wing added the aircraft detection, warning and control mission, when six radar squadrons were assigned to it.

Pulse-Doppler radar for aircraft detection has two modes.

The primary difference was that the SW antennas could be directed in elevation for aircraft detection.

In late 1940, the VVS developed the requirement for an on-board enemy aircraft detection system.

It was the first time aircrews utilized electronic counter-measures, chaff, and the aircraft detection devices in an operating environment.

Test aboard a ship showed aircraft detection at 60 km and reliable measurement starting at 40 km.

There was also a Newfoundland Aircraft Detection Corps.

In 1938, the U.S. Army's first radio-based aircraft detection and ranging system (later called radar) was developed on post.

In 1938, the first U.S. aircraft detection radar was developed at the Signal Corps Center.

Aircraft Detection Corps Newfoundland was an all-volunteer civilian unit meant to observe for suspicious planes and ships.

Low PRF radar have reduced sensitivity in the presence of low-velocity clutter that interfere with aircraft detection near terrain.

Two years later, Dr. Schonland was asked to develop an aircraft detection apparatus (later called radar) for the Defence Force.

In addition to completing Argon, Tikhomirov led the design of Selen (Selenium) radar systems for attack aircraft detection.

This was mounted in a rotating yoke that allowed it to scan around the horizon, and to elevate for what was hoped would be improved aircraft detection.

Aircraft detection and tracking (Situational awareness IRST & air-to-air weapons cueing)

PCAS is passive and less expensive than active aircraft detection systems, such as TCAS.

In 1936, he successfully detected a passing aircraft by the Doppler-interference method; this was the first recorded demonstration in Japan of aircraft detection by radio.

From 1957-1959, the wing also controlled the 678th Aircraft Control & Warning Squadron, which performed the radar aircraft detection, warning, and control mission.

In 1932, progress at the Naval Research Laboratory (NRL) on radio interference for aircraft detection was passed on to the Army.

The Aircraft Detection Corps Newfoundland was created by the Commission of Government during World War II.

The Federal Aviation Administration will install all-weather aircraft detection systems at 14 busy airports, including the 3 biggest in the New York area, the agency said Wednesday.
