What is a radar sensor?

Radar sensors are used for contactless detection, tracking, and positioning of one or more objects by means of electromagnetic waves.

What is a field disturbance sensor?

Field disturbance sensor. A device that establishes a radio frequency field in its vicinity and detects changes in that field resulting from the movement of persons or objects within its range.

Where are car alarm sensors?

Car Alarm Door Sensors These sensors can be installed in the doors, trunk, and hood of a car, and they allow the control unit to sense whenever someone opens anything up to gain access to the vehicle.

  • Pulse Radar.
  • Continuous Wave Radar.

What can radars detect?

Radar (radio detection and ranging) is a detection system that uses radio waves to determine the distance (ranging), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.
