Radar is an object detection system that uses waves to determine the range, altitude, direction, or speed of objects. The object returns a small part of the wave energy to a dish or antenna that is normally located at the same site as the transmitter. In an automatic target tracking radar system to follow selected white signals in the presence of signals Interference, for the automatic tracking of selected received signals. Here in this project the radar is equipped with DC gear motor and its operation is controlled by AT89S52 microcontroller. The buzzer and speaker are used to indicate the target detection. In this project the RADAR antenna is placed at an altitude to follow several frequencies emitted by various radio stations. The rotation of the RADAR antenna is based on the signal traced by a pair of control signals based on infrared sensors generated through it. Once the signal is paired, the antenna will stop in that particular direction, which indirectly turns the relay to turn on the particular music indication system. In this way we can trace the signal and we can activate the desired frequency channel. By using an ultrasonic sensor, mobile targets can be detected and the distance between the target and the antenna can be determined. ZigBee modules are used for wireless communication between the transmitter and the receiver.
