Arduino Based RADAR System With TARGET Acknowledgement

RADAR 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. Small portable radar systems that can be maintained and operated by one person are available as well as systems that occupy several large rooms.

The radar dish or antenna transmits pulses of radio waves or microwaves which bounce off any object in their path. The object returns a tiny part of the wave's energy to a dish or antenna which is usually located at the same site as the transmitter.Arduino is a single-board microcontroller to make using electronics in multidisciplinary projects more accessible. The hardware consists of an open-source hardware board designed around an 8-bit Atmel AVR microcontroller, or a 32-bit Atmel ARM. The software consists of a standard programming language compiler and a boot loader that executes on the microcontroller.This project aims on the use of Ultrasonic Sensor connected to the Arduino UNO R3 (I made one myself. You can buy one or make one) board and the signal from the sensor further provided to the screen formed on the laptop to measure the presence of any obstacle in front of the sensor as well as determine the range and angle at which the obstacle is detected by the sensor. For this screen, we use Processing 2 software by Ben Fry and Casey Rease, Massachusetts Institute of Technology, Cambridge.Also, in addition to it, a set of LED's connected through the shift register and a buzzer also tells about the range of the obstacle. According to the range of the object, the green, yellow and red LED's glow up with variations in the buzzer output.

    Nice graphics.....but I think this is more of a SONAR than an RADAR. Theres a big difference.

    Agree its using an Ultrasonic Sensor putting it firmly in the sound domain rather than electro magnetic radio waves. The title needs to be changed to fix this. A true RADAR system would involve many problems requiring broadcasting licences etc.
