How far can a person reach across a table?
It depends on the length of the person's arm, and the width or length of a table (depending on the person's position at the table). For example, if a person can reach 2-feet, but they want to reach across the length of a 6-foot table, then they can't reach very far.
What is the smallest object radar can pick up?
The smallest object most radar can pickup is a bird. Radar used by air traffic control and civilians is less accurate than that of the military.
What is a typical radar operating frequency?
Typical radar operates in the 50 to 330 megahertz bands. However, long range radar uses ultra high frequencies in the 300 to 1,000 megahertz range.
How does a radar gun work?
the RADAR transmitter sends out a pulse of radio wavesthe radio waves bounce off objectsthe RADAR receiver picks up the reflected pulses of radio wavesthe round trip travel time is measured electronically or displayed on a 2D screenthe travel time tells how far away the objects areMost modern RADARs use radio waves in the microwave band but HF band, VHF band, and UHF band radio wave have also been used.Older RADARs use a mechanically rotated or wobbled dish antenna, but many newer RADARs use a stationary Electronically Phased Array flat plane antenna (this type of antenna is another topic just by itself).LIDARs work the same but use light wave pulses generated by LASERs instead of radio waves.A basic summary of how radar works is that a pulse is transmitted and any return or echo is listened for. If a return is sensed, the timing between the transmission and the reception of the echo is used to determine how far away an object is. There are some other ways in which radar works as well.Radar is something that is in use all around us, although it is normally invisible. Air traffic control uses radar to track planes both on the ground and in the air, and also to guide planes in for smooth landings. Police use radar to detect the speed of passing motorists. NASA uses radar to map the Earth and other planets, to track satellites and space debris and to help with things like docking and maneuvering. The military uses it to detect the enemy and to guide weapons.Radio pulses are transmitted from the antenna, reflect back off objects, and are received again by the same antenna. The time is measured from transmission to reception and used to calculate distances to the objects. In most systems the time measurement & distance calculation are a single implicit operation done directly in the display by calibrating it in distance not time units.
Can sonar work in air?
NO. We call that radar.
How far does the radar on a F-22 reach?
The AN/APG-77 Radar of the F-22 Raptor has a greater range than 460 kilometers which is more than 286 miles.
Can somebody explain the entire plot of Modern Warfare 2?
Terrorists are threatening America then they copy some satiliter radar and then they reach America and invade and you have to stop them at all costs
Is radar 2D or 3D?
Both. Original radar is 2D and was invented in 2D. Modern radar is in 3D and is generally used for ground penetrating radars. Eventually 3D will be incorporated into new modern warships and air defences.
Is 2000 feet too far for a police radar to detect?
this is completely dependant on the range of the specific radar.
Who made the radar?
As far as I know, radar was invented by a Hungarian scientist named Zoltan Bay. That radar was first used in World War II by the British troops.
What is the different of a telescope and radar?
Radar is used to track things, while the telescope can only magnify or see things from a far distance. Radar is visible, while a telescope is not. Telescopes are old, radar is new (:
How far inland did the 2011 japan tsumami reach?
it reach far far in
Do aeroplanes have radar computers in them?
Larger aircraft will usually have radar. Small planes do not.
What sort of radars do submarines have?
If a submarine has a radar at all, it is generally a smaller, low power unit. The most modern subs don'e have any radar gear on them at all. The signal from a radar unit can be detected by modern countermeasures equipment, and that locates the user of that radar. Bad news for a submarine, a vessel that is designed to operate in or from hiding.
Can a Doppler radar be used to study tornadoes?
Yes. Doppler radar is one of the most important tools in the modern study of tornadoes.
What are the benefits of having a radar detector?
Having a radar detector will alert you when a Police Car with its speed radar is near. The Radar Detectors will produce an audible signal alerting you of this, and will do so far in advance of when you are able to see the Police Car.
Do the police have to be stopped to radar you?
The answer, both technologically and legally, is "No". Most modern in-car Police radar systems can work while the vehicle is moving.
