RADAR (Radio Detection & Ranging) is an object detection system which uses radio waves to determine the range, altitude, direction or speed of objects. Radar systems come in a variety of sizes and have different performance specifications. Some radar systems are used for air-traffic control at airports and others are used for long range surveillance and early-warning systems. A radar system is the heart of a missile guidance system.
In this, we are using ultrasonic sensor instead of RADAR antenna system. Ultrasonic is a non-contact level measurement method that uses sound waves. So technically, the technology used here in prototype design is SONAR(Sound Navigation & Ranging). Ultrasonic transmitters operate by sending a sound wave, generated from a piezo electric transducer, to the media being measured. The device measures the duration of time it takes for the reflected sound wave to return to the transducer. The successful measurement depends on reflection from the process material in a straight line back to the transducer. Distance measurement and angle of an object is acurrately possible.
This project can be used for security and surveillance for air defence system. The ultrasonic sensor module HC-SR04 moves to scan particular area using servo motor. The ultrasonic sensor can detect an obstacle upto 4 meters range. The data from the sensor is processed by Atmega328 microcontroller (Arduino UNO). It is transmitted to control room using zigbee modules. It is received and sent to PC to plot RADAR graph. We are using arduino Processing IDE to draw graph.
