Things were a little worse when the first squeals came from the radar two days later.
His hands were shaking worse when the automaticradar signals began to come through more clearly.
He washed his mouth out and grabbed for the radar key, banging out a report on this.
He checked his chronometer and flipped over the micropages of his Ephemeris; the big radar at Washington was still out of line with him, and the signals had to cut through too much air to come clearly.
The amulets were contained in slender bracelets and were designed to trap radar impulses.
The fused blip was still visible on screen as the radardishes tracked it, moving in a way that indicated a steep downward plunge.
Illustration] On every ship and plane in the task force, eyes were glued to the radar screens.
Its bulkheads were banked withradar and telemetering devices.
Oswald, a radar operator, was very quiet, kept to himself, and did not appear to have any close friends.
This necessitated a lot of change of aircraft call signs, codes, radio frequencies, radar frequencies.
Cornelius Brown, and Sergeant Brown is the most competent sergeant in the field of radar that I have ever encountered.
And when the radar screen would pick up an aircraft, you would then challenge that aircraft?
Radar is very susceptible to homing missiles, and this piece of equipment is used to put your radar antenna several miles away, and relay the information back to your site which you hope is relatively safe.
He had a radar specialization number, but we used him as a clerk.
That's right, along with the range capabilities of the radar sets and their blindspots and so forth and so on.
And I suppose all the men who worked with the radar sets knew these things?
There are some things which he knew on which he received instruction that there is no way of changing, such as the MPS 16 height-finder radar gear.
Oswald was not enthusiastic about his job, and performed about as well as the average radar operator.
Sometimes he relayed information to other radarsites in the Air Force or Navy.
There was actually noradar site setup at that area, and we just got the gear and other material and trucks and apparatus and things, and equipment was repaired and made ready for the next operation.
For instance, there is under development, I understand, a sort of a radar type of fence so that you can see if a person comes through a certain area without there being any fence there.
He also volunteered the information that he had offered to the Soviet authorities any information which he had acquired as an enlisted radar operator in the Marines.
No, but he was a Marine and he had been trained as an electronics radar specialist.
He mentioned that he knew certain classified things in connection with having been I think a radar operator in the Marine Corps, and that he was going to turn this information over to the Soviet authorities.
Bond was doing the calculations, based on the rocket's travel through the radar beam.
The dust cloud that marked an oncoming vehicle grew larger, and in a few minutes they saw the panel truck and the trailer with radardish mounted on it.
He kept right on going until his head banged painfully on the bottom of the nose-cone radar unit.
Jerry watched the shape on the radar screen climb to higher altitude and asked, "What's his velocity?
The pilot brought it in over the big radar antenna on the laboratory roof, then dropped onto the runway for a three-point landing opposite the orchard.
It's a panel truck, loaded with equipment, and they pull the radar antenna behind it on a trailer.
He might have had a training first and then theradar operation next.
I would assume that there was a relationship to some discussion of this experience and training in the Military Corps in the electronics and radar that suggests the drafting or because I knew of some possibilities in that area.
It swept through the defenses east of that mountain with demolitions and flamethrowers, then moved south toward Radar Hill, the eastern stronghold of Hill Row.
Inside there still remained stubborn Japanese defenders who continued to resist the contest for Radar Hill, as did the defenders within Amiangal Mountain’s extensive tunnels.
Behind the counter, one of the four rangers on permanent duty at the station was transferring a radar storm plot onto a weather chart.
A radar gauge bounced a beam off the bottom of one of the holes.
Applied with great economy of force, these landings produced fleet anchorages, fire support bases, auxiliary airfields, and expeditionary radarsites for early warning to the fleet against the kamikazes.
Wallace and his 8th Marines arrived from Saipan, initially to capture two outlying islands, Iheya Shima and Aguni Shima, to provide more early warning radar sites against the kamikazes.
Some of the artillery regiments had to absorb a flood of radartechnicians and antiaircraft artillery gunners from the old Defense Battalions at the last moment.
In that case, they may hope merely to approach near enough to obtain adequate radar echoes.
The first task was to rig the ship with absorbing screens to prevent radar echoes and nullify this means of locating them from Earth.
I keyed the chart file, flashed pages from the standard index on the reference screen, checking radar coverages, beacon ranges, monitor stations, controller fields.
And again I reached out-- A radar man at a site in the Pacific, fifteen thousand miles away, rose from his chair, crossed the darkened room and threw a switch.
Men labored over their plotting tables, noting the information the radarechoes brought back; slowly piecing together the picture.
That ground radar isn't effective below three thousand feet," Morrow reminded him.
But it appeared that a small radio set would have the power to reach anywhere in the Solar System, not to mention the extensive refinements of any television and/or radar set-up.
Radar blanketed the skies, rocket missiles stood on their firing-racks, long-range bombers waited to deliver atomic death and swift jet-fighters waited to do battle with them.
Before him was the familiar maze of instrument dials and signal lights and switches crammed around a glowing, green-blotched radar scope.
But one fact was added: both official groups said they were deeply interested in the reports for "reasons of security," that a thorough investigation would be made, and that radar surveillance along the West Coast would be intensified.
Two minutes later, a bright spark appeared on his radar scope.
He jabbed a button, and a motor purred, rolling out the retractable radar antenna.
He glanced at the parabolic radar antenna, rearing its head a dozen feet above him.
Use a P-charge if you can't spot him by radar or sonar.
Shortly after midnight, near Savo Island, Callaghan’s cruisers picked up the Japanese on radar and continued to close.
Air defense crews with small-caliber antiaircraft guns and tracking radar practice in conjunction with the early warning network and air defense communications.
After target identification they practice holding their weapons on the aircraft by radar or visual sighting.
The base would give you a heading to fly for couple of minutes then change to another heading so they could pick you out of the other planes on the radar screen.
Illustration: The small meteor ripped through the Space Bird's crew compartment, blinding theradar scope and severing communication with Earth.
According to the usual version, George Koehler had accidentally learned of two crashed saucers at a radar station on our southwest border.
Maybe few of the things sighted out in the Southwest have beer our test rockets, but that doesn't explain the radar reports in Canada and Japan.
The Air Force replied that there was not enough radar equipment to blanket the nation, but that its pilots were on the lookout for the saucers.
When radar trackers saw that a disk was off course and could not be realigned, the nearest station then sent a special signal to activate the detonator system.
As the missiles climbed high into the stratosphere, the satellite's radar could pick them up and keep them on course by remote control.
Unless the radar boys are way off, some of those saucers are enormous.
I believed, that he had told me about the radar tracking.
Alarm was increasing, and there were demands that radarbe used to track the disks.
Suppose radar or some other device warned you a meteorite was coming toward you head-on.
Radar or other devices may have to be developed to detect approaching meteorites at a distance and automatically change a space ship's course.
At first, the sightings were due to imperfect controls; the disks sometimes failed to keep their altitude, partly because of conflicting radio and radar beams from the countries below.
As it passed, Chiles noted a snout like a radar pole.
Being seen meant making a sufficiently distinguishable blip on somebody's radar screen to arouse comment over a blip where, according to schedule no orbiting blip should be.
At this point, unfortunately, a fault in the trackingradar transmitter had resulted in it losing contact with the target.
It was a good thing space cruisers depended on their radar and not on sight, he thought.
Besides, radar screens were more dependable than eyes, even though they could pick up only solid objects.
A senior space officer was seated before a simple panel on which there were only a dozen small levers, a visiphone, and a radar screen.
It would make an outstanding blip on any radar ’scope.
If anything comes within a dozen miles of us, the radar unit covering that sector will at once set automatic machinery in operation, and the rockets will shoot the ship out of the path of the meteor.
Morey snapped the switch from the general radar to the beam receiver, that he might locate the machine exactly.
The two radar beams were kept focused constantly on the Pirate's craft.
High above the planes they went, for with hisradar Arcot could trace them.
