Review on Unauthorized Object Detection Using Mini IR Radar

Abstract

Both military bases and airports utilize radar to detect unwanted objects. In order to find objects, radars use the echo detection principle. The reflection of echo waves in the air is timed based on how long it takes for the signal to be received. This information is used to calculate the object's distance. Infrared technology is what we suggest using to simulate this idea. An IR sensor radar that rotates continuously at 360 degrees makes up our system. The radar continuously emits infrared light while monitoring reflection. The radar stops and sends a signal when it notices reflection from any object within its field of view. Additionally, the radar transmits the angle at which the object was detected. Here, a tiny IR transmitter and receiver pair is used. To control the operation of the circuit, the pair is interfaced with a microcontroller. Radar input is continuously received by the microcontroller. The radar alerts the microcontroller when it detects an object. Now that it has the data and the radar direction, the microcontroller can determine the angle at which the object was discovered.
