Diagram depicts a surface-to-air missile system showing the accuracy radar provided. Long-range search radar emits radio waves that bounce off an unidentified aircraft and return flight-path information to a control computer, which activates tracking radar to lock on the target. If the target is confirmed to be an enemy, the control computer launches the missile and guides it with a command radio.
