Defense radar systems:
Defense radar systems [14] is a used of radio waves to analyzed the range of angles or distances and velocity of speed of objects. Its can be mostly used for bunkers, warships, aircrafts, spacecrafts, guided missile systems. That systems consists of transmitted to waves or microwaves produced the electromagnetic wave. It transmitting to the antenna. The antenna operated both transmission and receiving the operation to determine the properties of the objects. Radar developed and used for defense purposes that waves sequences for pulses or continues from the waves transmitter hit and reflect the objects and return the receiver, through come the information about the object location and velocity of objects and position of points. Its used WW2. A key in moderate to develop was the cavity of magnetron in the UK, which allowed the creation of compare the small systems with sub-meter resolutions [15]. That full from of radar is “Radio Detection and Ranging” or “Radio Direction and Ranging”. The modernized radar system are controlled the air and terrestrial traffic control. Controlled the air defense systems, antimissile systems, marine radars to position of landmarks and other ships, ocean surveillance systems, and outer space surveillance, assignation systems, metrological precipitation monitoring. Controlled and monitoring the flight control systems, and ground penetration radar for especially used for geological observations, and controlled the waves signals that purposes of public health surveillance.
