pulse radar

This is in contrast to the later development of pulsed radar, which determines distance directly.

Already he can feel the pulsing radars questing out from the Missouri line.

It resembles a fine weaving or an immense, pulsing radar screen.

Already he can feel pulsing radar energies directed downward from the dome of the sky.

As pulsed radars were initially being developed, the use of very narrow pulses was examined.

The primary surveillance radar is usually a pulse radar.

The experiments with pulsed radar were continued, primarily in improving the receiver for handling the short pulses.

The advantage of combining doppler processing with pulse radars is to provide accurate velocity information.

A conventional pulse radar spends most of its time turned off, listening for the reflections of its own signal.

This was immediately connected to coherent pulsed radars, where velocity information was extracted.

As a result, the split-anode magnetrons were extremely unstable sources and their use in the design of pulsed radar was not successful.

The stations used a number of a long-range pulse radar systems known as the AN/FPS-19.

Radar companies and police next came up with pulse radar, which utilizes a radar gun with an on/off switch.

You could in the Reefs of Space perhaps even avoid the wash of pulsed radar which the Machine would flood through the system.

The test consisted of bouncing pulsed radar signals off the surface of the moon and checking the measurements obtained against previously recorded data.

Although the detection range was small and the indications on the oscilloscope monitor were almost indistinct, it demonstrated the basic concept of a pulsed radar system.

That had to await the invention of pulsed radar, and later, additional encoding techniques to extract this information from a CW signal.

The station consisted of three pulsed radars, and support facilities, including barracks, married quarters (trailers), a school, chapel, bowling alley and gym.

The on/off switching was difficult for radar detectors to pick up - until this year's generation of radar detectors introduced a pulse radar alert feature.

Pulse radar that automatically comes into operation if the HPIR radar cannot determine the range, typically because of jamming.

The station received an AN/FPS-19 pulse radar and was designated as station LIZ-1.

It uses the Iranian Toloue-4 turbojet engine and the DM-3B mono pulse radar used in Noor.

In January 2004, Iran announced that it has started manufacturing the DM-3B mono pulse radar for Noor missile.

A continuous wave frequency modulated (CWFM) or pulsed radar waveform is normally used to provide range resolution.

When using a pulsed radar, the variation between the phase of successive returns gives the distance the target has moved between pulses, and thus its speed can be calculated.
