RADAR, short for RAdio Detection And Ranging, is navigation technology used to detect and navigate objects through radio waves. A RADAR dish or antenna transmits radio waves in to the space. If these pulses bounce off any object, a fraction of pulses returns back to the receiver antenna of the RADAR. The Signal strength of the received pulses and delay between transmission and reception are used to calculate the distance and orientation of the object.
They are generally used for military applications to detect the aircrafts in the space boundaries.
