microwave sensor

With the help of the suit's microwave sensors he found it in the first twelve hours.

Microwave sensors are executed in a wide variety of techniques.

Two displayed the terrain using thermal infrared and active microwave sensors.

The fence, built with American technology, has microwave sensors and alarms and cameras.

To satellite microwave sensors, surface melt appears to be open water rather than water on top of sea ice.

ERS, with its microwave sensors, will give us the best view we've ever had.'

This is why the tool of choice for determining ice concentration is often a passive microwave sensor.

Heavy security on the perimeter, including microwave sensors and an array of cameras, allows for freer movement within the compound.

Security experts also are hurrying to complete a high-tech monitoring system, including radar, electromagnetic barriers and microwave sensors.

On the other hand, pressure-sensitive mats were widely used for opening grocery doors before they switched to microwave sensors.

The visual wavelengths were useless-we couldn't see a thing through the ports-but the microwave sensors let us look to the horizon.

He did not know yet how the ship had managed to remain invisible to all equipment except the microwave sensor but he intended to find out.

This principle underlies all passive microwave sensors and most passive infrared sensors.

On a smaller scale, astronomers are heavily dependent on liquid helium for cooling infrared and microwave sensors in their telescopes.

During the Pluto night Proserpina requested permission to drop small, rugged microwave sensors around the zand gathering areas.

Ilse glanced at her console; satellite radar and microwave sensors told her a surprising amount about the upper part of the ocean.

It uses infrared, rather than microwave sensors, and they are fitted to the external console, rather than added to the urinal bowl itself.

Zsasz collapses the tunnel in on Nightwing, but is stopped by Batman who had made the agonising journey through a microwave sensor to stop him.

For example, many dual-tech sensors combine both a PIR sensor and a microwave sensor into one unit.

Other thermal sensing technologies include microwave calorimeters and bolometers,and quasi-optic pulsed microwave sensors.

Microwave sensors are ideal for use in moist, vaporous, and dusty environments as well as in applications in which temperatures vary.

He joined NASA in 1999 as head of the Microwave Sensors Branch at Goddard.

So, while reliable for measuring area most of the year, the microwave sensors are prone to underestimating the actual ice concentration and area when the surface is melting.

Just as with ultrasonic level sensors, microwave sensors are executed at various frequencies, from 1 GHz to 30 GHz.

Field type sensors such as Eddy Current, Capacitive, and Microwave sensors are useful in harsh environments and for long duration testing.
