The purpose of this project is to design and construct automatic missile detection and destroying system.  This system is designed to detect the moving targets (missile) and fires them with help of laser gun.   This system consists of an intelligent 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 triggering the firing mechanism in the direction of target (missile). The firing in the system is done through a Laser GUN.   The main controlling system of the whole system is a microcontroller. Sonar sensor, stepper motor and laser gun are interfaced to Microcontroller. The DC motor based movable platform with sonar sensor mounted on it continuously checks for target and feds this data to the Microcontroller. The Microcontroller activates the laser gun along with Buzzer when the target is fixed. Target distance will display on LCD. To perform this task, Microcontroller is loaded with an intelligent program written in embedded ‘C’ language.  

The main objectives of this project are:

1. Continuous monitoring of the moving target.
2. Firing through laser gun.
3. Audible alerts using Buzzer.

The major Building Blocks of this system are:

1. PIC Microcontroller.
2. Regulated Power Supply.
3. Sonar sensor.
4. Stepper motor with driver.
5. Buzzer with driver
6. Laser/High power LED gun.
7. LCD display.
8. Crystal oscillator
9. LED indicators
10. Reset

Software’s used:  

1. PIC-C compiler for Embedded C programming.
2. PIC kit 2 programmer for dumping code into Micro controller.
3. Express SCH for Circuit design.
