Ultrasonic Radar

Radio Detection and Ranging (RADAR) is a device which is used for monitoring a particular area 24/7. The basic needs of these are security. RADAR is an object detecting device. It can be used to detect aircraft, spacecraft, missiles, vehicles, weather formation and so on. Radar is an addition to man’s sensory equipment which affords genuinely new facilities. It consists of Trans-receiver and Processor. RADAR can be of many types. Ultrasonic RADAR is an object detecting system which is used to monitor an area of short range. This system consists of an Arduino which is interfaced to an Ultrasonic Sensor mounted on a Servo Motor. A microcontroller is used to interface the ultrasonic module. Ultrasonic module consists of a transmitter and a receiver. The module transmits the sound waves to the object and the transducer receives the waves reflected back from it. The measurement of the distance is calculated by the total time taken from sending the waves and receiving it with respect to the velocity of sound. The calculation is done by the programmed microcontroller and displays it on LCD screen.
