Microcontroller Based Missile Detection and Destroying

This project is to design and construct automatic missile detection and destroying system. The system is designed to detect the target (missile) moving in multiple directions. The destroying system moves automatically in the direction of missile and fires it upon fixing the target. This system consists of a SONAR based object tracking system that continuously monitors the target. Upon detecting the target it sends the target's location to a Central Control System. The Central Control System takes the action of moving the firing mechanism in the direction of target missile. Upon fixing the direction, it sends the control command to firing system to attack the target.

This project is divided in three part RF Transmitter, RF Receiver, and microcontroller.

The main objectives of this project are:

1. Monitoring the moving target.

2. Real time monitoring of target

3. Works in any lighting conditions.

4. Automatic target attacking.

5. Controlling the robot using RF TX and RX

This ultrasonic proximity detector comprising independent, battery or AC powered transmitter and receiver section make use of a pair of matched ultrasonic piezo ceramic transducers each operating at around 40 kHz. This circuit is used to get reflected signals of 40 KHz from the a missile to feed that to a program to the microcontroller to switch on appropriate load while the program is executed at the microcontroller end. When the AVR microcontroller receives the signal from ultrasonic receiver it activates the door gun by triggering the gate of MOSFET through a transistor. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. Then this is converted to DC using a Bridge rectifier. The ripples are then removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

OpAmps are used for amplification of the weak signals received upon reflection from the obstacle, by the receiving ultrasonic transducer sent by the transmitting one, to switch on appropriate load while the program is executed at the microcontroller end.

The project consists of the ultrasonic transmitter and receiver each of which works for the frequency of 40 kHz.

At the receiver side the received signal is amplified and given to the microcontroller which is used as to operate the relay driver (ULN2003) for operating the relay to drive the loads.

Target acquisition and tracking are frequent domains of active sensing methods such as RADAR, Ultra-sound, or LASER scanning. The ability to track targets at manipulation range can significantly reduce the cost and complexity of manipulator control. Ultrasonic sensors, in particular, provide an ideal platform for experimental development in range detection. They are cheap, readily available, and increasingly possessed of high-resolution sensors. Its various Applications range from robotic security systems to environments such as production lines where distance measurement and obstacle measurement and manipulation of objects are routine tasks with potential for wide-scale automation and defense.
