The term 'TYPE OF RADAR' can be summarized by the Doppler Radar, which is a seven letter word. Doppler Radar is a type of radar that uses the Doppler effect to measure the velocity of objects. It works by sending out a beam of electromagnetic waves and then measuring the frequency of the waves that are reflected back. The frequency of the reflected waves is then compared to the frequency of the original waves, allowing the velocity of the object to be calculated. Doppler Radar is used in many applications, such as weather forecasting, air traffic control, and military operations.
