2. Radar(Radio Detection Ranging):Radar is an object detection system
which uses radio waves form identifying objects……
• Altitude
• Direction
• Range
• Speed of moving position
Principles:
• The radar dish or antenna transmits pulse of radio waves which bounce
off any object in their path.
• The objects returns a tiny part of the waves energy to a dish or antenna.
• This usually located at the same time site at the transmitter.
• Calculate the emitted and reflected waves time by computer for
measuring object location properly.
