- 3. INTRODUCTION: Basically anyobject thrown at a target with the aim of hitting it is a missile. In modern world,missiles are detected and destroyed by anti-aircraft system whose path is controlled by radio signals or by internal homing devices.
- 4. HISTORY OF ANTI–MISSILE SYSTEM: The first serious attempts at SAM development took place during World War II, although no operational system were introduced. Historically notable systems include the American Nike Ajax, the first operational guided missile SAM system, and the Soviet Union's S-75 Dvina, the most-produced SAM.

- 6. AVR ATMEGA 32MICROCONTROLLER: ATmega32 is an 8-bit high performance microcontroller of Atmel’s Mega AVR family with low power consumption. Atmega16 is based on enhanced RISC. Most of the instructions execute in one machine cycle. Atmega16 can work on a maximum Clock frequency of 16MHz. ATmega32 has 16 KB programmable flash memory, static RAM of 1 KB and EEPROM of 512 Bytes bound by Harvard Architecture. The endurance cycle of flash memory and EEPROM is 10,000 and 100,000 respectively. ATmega32 has various in-built peripherals like USART, ADC, Analog Comparator, SPI, JTAG etc. Each I/O pin has an alternative task related to in-built peripherals.
- 7. PIN DIAGRAM ATmega32is a 40 pin microcontroller. There are 32 I/O lines which are divided into four 8-bit ports designated as Port A , port B, port C and port D. ATmega32 has various in- built peripherals like USART, ADC, Analog Comparator, SPI, JTAG etc. Each I/O pin has an alternative task related to in-built peripherals.
- 8. L293D MOTOR DRIVERIC The most common method to drive DC motors in two directions under control of a computer is with an H-bridge motor driver. We can make our own H bridge using transistors but it will be better if we use a ready made IC named as L293D, it’s a dual half H brige IC. We can drive a maximum of two DC motor and one stepper motor using one L293D.
- 9. VOLTAGE REGULATOR 7805 7805 is a voltage regulator integrated circuit. It is a member of 78xx series of fixed linear voltage regulator ICs. The voltage source in a circuit may have fluctuations and would not give the fixed voltage output The voltage regulator IC maintains the output voltage at a constant value. The xx in 78xx indicates the fixed output voltage it is designed to provide. 7805 provides +5V regulated power supply . Capacitors of suitable values can be connected at input and output pins depending upon the respective voltage levels.
- 10. DIODE IN4007 Thesediodes are used to convert AC into DC these are used as half wave rectifier or full wave rectifier. Diodes of number IN4001, IN4002, IN4003, IN4004, IN4005, IN4006 and IN4007 have maximum reverse bias voltage capacity of 50V and maximum forward current capacity of 1A. Diode of low capacity cannot be used in place of diode of high capacity.
- 11. RF MODULE: TheRF module operates at Radio Frequency(RF) . The corresponding frequency range varies between 30 kHz & 300 GHz. RF signals can travel even through obstruction between transmitter & receiver. Any RF module comprises of an RF Transmitter and an RF Receiver
- 12. ROBOT CHASSIS: Achassis is a base - the physical frame or structure of an automobile, an airplane, a desktop computer or other multi-component device. In military terms, it refers to the frame on which a cannon carriage moves backwards and forwards
- 13. A steppermotor is another kind of electric motor used in the robotics industry. Stepper motors move a known interval for each pulse of power. These pulses of power are provided by a stepper motor driver and are referred to as a step. STEPPER MOTOR:
- 14. ULTRASONIC SENSOR UltrasonicRangefinder is used to find range of an obstacle from the sensor. It works on a principle similar to RADAR or SONAR which evaluate attributes of a target by interpreting the echoes from radio or sound waves respectively.
- 15. LASER – LIGHTAMPLIFICATION BY STIMULATED EMISSION RADIATION Any device that emit highly amplified and coherent radiation of one or more discrete frequencies. LASER delivers light in an almost-perfectly parallel beam (collimated) that is very pure, approaching a single wavelength. It is used to produce a coherent non dispersing beam of light by multiple refractions inside a highly polished glass cavity.
- 16. WIRELESS VIDEO CAMERA It is a wireless transmitter carrying a camera signal. The camera is wired to wireless transmitter and the signal travels between the camera and the receiver. The sound you hear on a radio is transmitted wirelessly and you can tune it to a certain frequency and hear the sound. The power is provided by a battery or transformer. The Receiver A wireless receiver has only one function. After the camera and wireless transmitters have provided the wireless video signal the receiver collects this signal and routes it the Monitor, TV, VCR , DVR or PC (or alternative recording or viewing device). Video Transmitter: Video Transmitters can be obtained separate from cameras.. Instead of the wire from the camera to the recording device or monitor the wireless signal will send the video. Again you will need to provide power to the camera and the transmitter.
- 17. WORKING: The systemis 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.

- 19. CONCLUSION: By usingultrasonic waves, we can detect the missile then micro controller activates the destroyer. This can be applied in various defense fields to protect the Nation from foreign attacks. In case of global military conflict, the role of anti-missile defense becomes very important. Although anti-missile defence with a hundred percent reliability was not reached by any country, huge efforts are put into this area. For this purpose early attack detection systems, controllable rockets, high power lasers are used.
