microwave detector

This has happened in the past when people started using X-ray and microwave detectors."

A radio and microwave detector is also included, which reads radio power directly.

Microwave detectors could no longer plainly 'see' it, although it was still visible to the human eye.

Instead the experimental results in this paper focus mainly on the resolution and linearity of the system when used as a microwave detector.

The cabin contains multiple radio and microwave detectors, which can be switched into the focus beam for different science observations.

Its high frequency microwave detector is cooled to just 0.1C above absolute zero, the coldest temperature possible.

It was a plywood box with sheets of webbed steel that sheltered the optical and microwave detectors from outside emissions.

The device cannot hide an object from a human eye but only, as the New Scientist explains, from the "eyes" of a microwave detector.

They are similar to microwave detectors but can detect the precise location of intruders in areas extending over hundreds of acres.

It became obsolete around 1920, but later versions served as microwave detectors and mixers in radar receivers during World War 2.

Microwave detectors showed radiations from the aft section of her hull, which might still be inhabited, even though the fore sections were cold and silent.

Planck has microwave detectors looking for Cosmic Background Radiation — energy left over from the Big Bang.

Microwave detectors have recently revealed the presence of organic molecules in interstellar space, and optical spectra show traces of them in comets.

The Navy had financed efforts by Dr. Gaitan's group to develop inexpensive, hand-held microwave detectors that could be used for setting up communications equipment.

This meter is the only one which combines magnetic, electric, and radio/microwave detectors in one package, so that the entire nonionizing electromagnetic spectrum is covered.

A microwave detector is needed for soft top cars as the conventional system using ultrasonic sensors would result in false alarms caused by air movements within the vehicle.

For years scientists deployed high-flying aircraft, balloons and microwave detectors at the South Pole in search of evidence for anisotropy in the background radiation.

At the same time, the ship's microwave detector will be able to peer down into the atmosphere to look for the telltale signatures of water and ammonia among other substances.

Mars Dual Technology - PIR/Microwave Detector with Pet Immunity.

As part of his work within the SCALEQIT project, Wilhelm-Mauch has already developed a highly efficient microwave detector that can detect photons with 100% efficiency.

The detected voltage signal output of the Schottky barrier diodes typically used in microwave detectors have a square law relationship to the power being measured and meters are calibrated accordingly.

Microwave detectors respond to a Doppler shift in the frequency of the reflected energy, by a phase shift, or by a sudden reduction of the level of received energy.

In 1965 two American physicists at the Bell Telephone Laboratories in New Jersey, Arno Penzias and Robert Wilson, were testing a very sensitive microwave detector.

Not that the structure sensors failed to function within such a radius but there was no advantage in using them under these circumstances because the microwave detectors furnished results almost as quickly and with more accuracy.

Magal said the orders include Yael, the company's leading taut wire system; MagBar smart grids to protect water passes; and a smart fence-mounted, fiber-optic detection system and microwave detectors.
