How does radar work. How does radar work. The radar system sends out a signal in the form of a sound wave. This pulse is sent out from the radar dish on top of your boat. It can be used to detect aircraft ships spacecraft guided missiles motor vehicles weather formations and terrain.

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. How stuff works with 3d animation and excellent voice over. It rotates steadily sweeping the airspace with a narrow beam. When the signal is reflected by an object the radar computer determines how far away it is and where it is located.

As they strike objects in the atmosphere the energy is scattered in all directions with some of the energy reflected directly back to the radar. How does the radar work. Each pulse lasts about 0 00000157 seconds 1 57x10 6 with a 0 00099843 second 998 43x10 6 listening period in between. Here s a summary of how radar works.

Magnetron generates high frequency radio waves. Antenna acts as transmitter sending narrow beam of radio waves. The word radar is an acronym for radio detection and ranging and in its simplest form it consists of a transmitted radio signal aimed by an antenna in a particular direction and a receiver that. Police use radar to detect the speed of passing motorists.

Radar is a detection system that uses radio waves to determine the range angle or velocity of objects. It requires two types of readings for this to occur. Another key difference is that radar doesn t always stay in capture mode as the human eye does it also emits its own signal acting first as a source and then as a receptor of radio waves for. Duplexer switches magnetron through to antenna.

The transmitted radio waves move through the atmosphere at about the speed of light. As the radar antenna turns it emits extremely short bursts of radio waves called pulses. Radar of the type used for detection of aircraft.
