Question

define all the parts of radar and explain its uses

Answer 1

radar:-a radar is a device used to detect something with the help of radio waves the radio waves are tranmitted and then they are detected the time is noted that after how much time the wave is detected

two major parts of radar:-

Transmitter-this is a device which send radio signals in an area with a limited range

Detector-after being stuck by an object the radio waves are reflected back and they are sensed by a device known as detector

the formula for finding distance is

S=TV/2

s=distance,t=time taken by radio wave,v=velocity of radio wave, these are divided by 2 because the ray is reflected back so it covers double distance

modulator-it is a device which produces radio waves with time duration between 1 to 50 microseconds at high voltage

oscillator-it is a device which produce frequencies about 100khz


indicator is a type of display with the center point.the center point is the position of the detector and it shows a point where an object is detected

Answer 2

Radar is a detection system that usesradio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. Other systems similar toradar make use of other parts of the electromagnetic spectrum.
