scanning radar

H2S was the first airborne, ground scanning radar system.

Automatically, he glanced at the horizontally scanning radar, as he had done every few minutes.

In particular, conical scanning radars required some time to settle on an accurate track.

Uses a ground scanning radar to "match" topography against digital map data to fix current position.

He was also awarded a combination scanning radar and Loran set valued at $3,300.

The onboard electronics were based on a simple analog design, with a homing conical scanning radar sensor.

The most common form is an adaptation of conical scanning radar which compares the return from two directions to directly measure the location of the target.

During the visit, five controllers, sitting in thickly cushioned chairs, bent over consoles, scanning radar screens and giving instructions to Soviet pilots.

The FPS-17 detection scanning radars have fixed antennae oriented toward the Soviet Union.

The forward scanning radar of the Mirage was a complicated and sophisticated body of electronics, that required firstly a high degree of manual dexterity.

During the Second World War he worked on scanning radar technology and guided missiles, which may have influenced his subsequent alpha wave scanning hypothesis of brain activity.

Special surface scanning radar was added and in addition, the 40mm, 20mm guns and torpedo tubes were removed and replaced with three twin mount 3in guns 3"50's.

The Coast Guard accomplishes these tasks with the use of offshore patrol vessels (OPV), helicopters, surveillance aircraft, satellites and a network of land based surface scanning radar.

Other techniques, such as echo-sounding and soil scanning radar, are currently being developed, and are likely to be used more and more in the future for accurate location and surveying of sites.

The formation sailed on serenely, unaware of the enemy beneath their tail, creeping up in the blind spot where the forward scanning radar could not discover them and rapidly moving into a position up sun.

This was the area that was the subject of the Amarna Royal Tombs Project ground scanning radar investigation, which showed several anomalies, one of which was proved to be KV63.

The Rafale avionics consists of an RBE2 electronic scanning radar, the OSF passive visual system and SPECTRA electronic warfare.

In other places the tunnel described a series of shallow curves, cutting down the view provided by the scanning radar to a couple of hundred metres or less, so that he seemed to float alone in the chill blackness.

In the Pacific theater, B-29's were equipped with the improved H2X radar called the AN/APQ-13, a ground scanning radar developed by Bell, Western Electric, and MIT.

Given an example antenna that generates a beam of 2 degrees width - fairly typical - a conical scanning radar might move the beam 1.5 degrees to one side of the centerline by offsetting the feed slightly.

The successor of SY-1, designed by Peng Lisheng (彭历生) and designated as SY-1A, had a mono-pulse terminal guidance radar seeker replacing the original conical scanning radar seeker.

Light precipitation such as drops and flakes is subject to the air currents, and scanning radar can pick up the horizontal component of this motion, thus giving the possibility to estimate the wind speed and direction where precipitation is present.

Lots of useful stuff came from them, such as work on lasers and masers, fibre-optics, micro-miniaturisation in electronics, low temperature superconductors, linear motors, inertialess scanning radar, ground speed radar, etc, etc, but most of that has been sold off now.

Almost immediately after takeoff this morning in one of their American-built Awacs surveillance planes, Saudi Air Force personnel turned on scanning radars and computer systems that placed the sprawling expanse of the Arabian Peninsula, Iraq and Kuwait on a neat video screen.

The Firsters with her had sworn, and scrambled, one turning the scanning radar groundward, looking for a clearing, the pilot swinging south, to lay the latac parallel to the prevailing winds, the engineer hurrying to bleed gases from the envelope, ready to collapse it as soon as they could land.
