Doppler Effect: Speed guns commonly use the Doppler Effect principle. When a radar signal is bounced off a moving object, the frequency of the returned signal is shifted proportionally to the object’s speed. This shift helps calculate the object’s speed.
Radar Technology: Speed guns typically employ radar technology to emit radio waves and detect their reflection from moving objects. This helps in measuring the speed based on the time delay and frequency shift of the returned signal.
Infrared Sensing: While not typically used in conventional speed guns, infrared sensors can be used in some advanced motion tracking systems. However, they are not a standard component in traditional speed guns.
Laser Technology: Some modern speed guns use LIDAR (Light Detection and Ranging) technology, which involves emitting laser pulses and measuring the time it takes for the reflection to return. This helps in accurately determining the speed of the moving object.
