An Advanced Air Defence System Prototype using Arduino UNO

An Advanced Air Defence System is mandatory to ensure the safety of our country. Our proof-of-concept Air Defence System, comprises of Arduino UNO, two Servo Motors- one for horizontal sweeping and another for vertical sweeping, and an HC-SRO4 Ultrasonic Sensor to detect an object within the threshold distance. When connected to a power source, for every ten-degree increment in motion of the horizontal Servo-Motor, a top to bottom, 180-degree vertical sweeping is done for effective tracking. Once an object is within the threshold distance of the sensor, the HC-SRO4 Ultrasonic Sensor locks on to that object and an LED or a Laser Diode continuously turns on and off simulating the launching of a projectile. This process continues until the object is out of the threshold range of the sensor. In real life, since fighter planes are capable of travelling at supersonic speeds, enemy tracking using Ultrasonic Sensors is almost futile. Hence, Infrared Enemy Detection and Tracking Methods are more commonly used as active search systems like radar, must emit electronic signals that tip off the enemy to its presence and they have the capability to detect enemy aircrafts at a range of about 200-600 km. In the future, further enhancements can be done by AI Integration (for example: IRST Systems) to identify and track enemy aircrafts, analyse patterns, etc.
