This document describes the design of an infrared radar training module that can scan 180 degrees and detect objects from 20-150cm away. An infrared distance sensor is used to detect objects through triangulation by emitting and receiving infrared light. The sensor is rotated by a servo motor controlled by an Arduino, which sends distance and angle data to Processing software to visualize it as a dynamic radar display. The goal is to create a low-cost training module to teach students about radar technology, which could also be applied to home security systems or obstacle detection for robots.

In our project the main target is to develop a low cost radar training module for students to have an idea about what is radar. To visualize the sensed data from the IR sensor to a radar screen, Sharp GP2Y0A02 series infrared distance sensor was used to our project. Itll detect and measure anything within a 20-150cm range and it does this by triangulation method from where it emits a beam of IR and from when it receives it. Basically a pulse of IR light is emitted by the emitter. This light travels out in the field of view and either hits an object or just keeps on going. In the case of no object, the light is never reflected and the reading shows no object. If the light reflects off an object, it returns to the detector and creates a triangle between the point of reflection, the emitter, and the detector. We are using the arduino to control a servo motor that will rotate our IR sensor around 180 degrees. The arduino will then send the value from the distance sensor along with the current angel of the servo motor to the serial port. The project also used the programming language 'Processing' to visualize the data received as a dynamic graph. Although the main aim is to develop an IR radar training module, this infrared radar has other applications too. This can be used as a home security system by coupling it to an alarm and can be coupled to an obstacle avoiding mobile robot platform in order to maneuver in any terrain. The most important feature in this radar is that it is low cost radar.
