On its own, it isn't. Amplification requires input of energy - an antenna is entirely passive.

What is meant by the pointing direction of radar beam?
Which way the antenna is pointing.
What does radar use to determine velocity and location of objects?
Radar sends out a signal, either radio waves or microwaves. The signal then reflects off of objects and back to the radar. The radar logic calculates the time it takes for the signal to return and can then calculate the distance. The velocity is then measured by the rate of change in distance or by doppler shift. The doppler shift is a change in the frequency of the signal, as the signal is either compressed or stretched from impact with a moving object. The signal frequency is compressed if the object is moving toward the radar and stretched if the object is moving away. - - - - - Almost. Radar uses two inputs to determine the location of an object. The first is the length of time it takes the radar pulse to reach the target and return to the antenna. The speed of radio waves is 300,000 km/sec. Since it's got to go out and come back, divide that by two--so, if you send out 100 pulses per second and the antenna doesn't move, the radar can detect targets up to 1500 km away. (Since the antenna on a radar normally is movable, things get more complex than I want to get into at one in the morning, sorry.) The other is the position of the antenna. If your guy shows up at a 300-degree antenna position and it takes 0.01 millisecond for the pulse to return, he's 1.5 kilometers from your antenna at that specific azimuth. ----- Right on jmoreader. Also, the questioner should know that there are several different types of radar. Weather, Aircraft, or even the radar gun that cops use to check your speed. All of which work a little differently but rely on the same principles. A radar gun being the most simple as it doesn't really collect rangeing or position data, only velocity I believe. One interesting system is Composite Radar used for weather. There are inherent problems in using a single radar facility to view areas of rain, snow, or even turbulence within a storm cell. Most of the so called "curtain" effect is overcome by using several radar sites in different locations. When you view weather radar on television or elsewhere, the image you see is actually a computer generated image comprised from data collected by multiple radar locations. Viewing the weather from different "angles" provides a more complete and much more accurate image of the actual weather condition. As jmoreader pointed out, radar systems are generally quite complicated, but, the basic principles are fairly simple and common across the board. Send a signal out and analyze the return.
How does a Doppler radar determine the direction a storm is moving?
The Doppler part only detects motion towards and/or away from the radar antenna. To find a direction of travel (on any radar) you must watch the object (such as a storm) over time and watch it move. To find motion by doppler the radar must detect the frequency difference of the return signal - there will be a (very) small increase if the object is moving closer (and lower if moving away).
How does a radar system detect the the position of an object?
The radar antenna sends out a short pulse of radio waves in a direction, then listens for radio waves coming back. If any radio waves come back, then they must have hit something and echoed (bounced) back. The time it takes them to return tells how far away the solid object is that they bounced off of. Then the antenna turns to a slightly different direction and does the whole thing again.
What is a antonym for radar?
Radar
What is a radar mast?
A radar mast is a high platform to mount a radar antenna such as the radar has an unobstructed view.
You have new furuno radar gps and radar do you need antenas?
You need both a radar antenna and a GPS radar if this is marine then the radar antenna will perhaps include a Receiver and Transmitter as well and the GPS maybe a mushroom shape
What is palindromic antenna turner?
Radar
What radar do?
At the minimum, a radar is a device that can detect the range of the target object (ie. radar gun used by law enforcement). A more advanced radar can locate the range and direction of the target object (via the azimuth). For example, the old spinning radar antenna seen on TV can locate an object based on the detected range and the direction the antenna is facing at the time. These can still be used to track the weather as clouds can be tracked. The most highly advanced radar can identify just about everything about the target object as if it is in front of you. An example of use is tracking space junk.
What is the elevation of the Palos Verdes radar antenna?
1480'
You are beamed by a radio wave by a highly directonal antenna how to detect it?
radar
What is meant by the pointing direction of radar beam?
Which way the antenna is pointing.
What is the dofference between azimuth and elevation?
Elevation is a vertical lift and azimuth is a rotation around a vertical axis. An example of its use is in radar. The radar antenna rotates towards its target, its azimuth, and then lifts vertically to elevate the receiver then locks on to the target.
Why was the mcrowave invented?
Someone melted a chocolate bar while working on a radar antenna.
What are the health issues living near a Doppler radar?
Radiation exposure is a serious problem for residents in close proximity to a radar or microwave transmitting antenna.
How does synthetic aperture radar different from other radar?
Synthetic Aperture Radar synthesis a longer antenna (or Aperture) by integrating pulses together that overlap each other to exploit turn rate phenomena.
How Radar range related to Antenna gain?
