C) locating geostationary satellites D) receiving a signals in a radio receiver
 
Answer & Explanation Answer: A) detecting and locating the position of objects such as Aeroplanes

Explanation:

RADAR - RAdio Detection And Ranging.

A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. 

 

Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.

 

Radio waves from the transmitter reflect off the object and return to the receiver, giving information about the object's location and speed.
