RADAR is an acronym for Radio Detection and Ranging.

The system works by transmitting high-frequency radio waves, or microwaves (which are a type of radio wave), toward an object.

The waves bounce off the object, and a receiver in the radar system detects the reflected energy, known as an echo.

By measuring the time delay between sending and receiving the signal, the system can calculate the distance and velocity of the object.

This unit is derived from the SI units for displacement (meter) and time (second),

Velocity is defined as the rate of change of displacement over time (displacement/time).
