This document describes a missile detection and automatic destroy system that uses an ultrasonic sensor interfaced with a microcontroller to detect missiles. It calculates the distance to the missile using ultrasonic waves and rotates a sensor mounted on a stepper motor by 180 degrees. When a missile is detected, laser lights and a stepper motor are used to automatically track and destroy the missile. The system provides discrete distance measurement of objects and can detect small objects over long ranges.

3. ABSTRACT:
 This proposed system uses an ultrasonic module interfaced
to a microcontroller of 8051.
 An ultrasonic transducer comprising of a transmitter and
receiver are used. The transmitted waves are reflected back
from the object and received by the transducer again.
 The total time taken from sending the waves to receiving it
is calculated by taking into consideration the velocity of
sound.
 The distance is calculated by a program running on the
microcontroller and displayed on an liquid crystal display
screen interfaced to the microcontroller through ZigBee
Wireless communication.

4. COMPONENTS:
MICRO CONTOLLER OF 8051
ULTROSONIC SENSOR
LASER LIGHTS
STEPPER MOTER
LCD
L293DRIVER

5. BLOCK DIAGRAM:

6. MICROCONTROLLER:
 It has a modified hardware
architecture 8-bit RISC processor
code.
 The ATMEGA 328 is a single chip
microcontroller created by Atmel
in the mega AVR family.

7. LCD SCREEN:
 LCD (Liquid Crystal Display) screen
which consists of two lines with 16
characters each.
 Contrast on display depends on the
power supply voltage and whether
messages are displayed in one or two
lines.

8. ULTRASONIC TRANSDUCER
 Ultrasonic transducers are used in
systems which evaluate targets by
interpreting the reflected signals.
 Ultrasound is used for measuring
speed and direction.

9. L293D (DRIVER MOTOR):
 L293D is a typical motor driver or
Motor Driver IC which allows DC
motor to drive on either direction.
 It is a 16-pin IC which can control a
set of two DC motors
simultaneously in any direction.

10. STEPPER MOTOR:
 It is a class of rotary electrical
motor that converts electrical
energy into mechanical energy.
 Its speed can be controlled over
a wide range of variable supply
voltage, which rotates 180
degrees.

11. LASER LIGHT:
 LASER(Light Amplification Stimulated
By Emission Of Radiation) creates and
amplifies electromagnetic radiation of a
specific frequency through the process
of stimulated emission.
 Laser light systems create sharp light
beams, highly focused over long
distances. Like laser lighting
displays, laser lights are used as
an entertaining medium.

12. WORKING:
 The system controllers used to detect missile object.
 An ultrasonic transducer with a transmitter and
receiver is used. They produce sound waves that
transmit and when it reflects.
 The total time required to send the waves and receive
it calculated the velocity of sound.
 The distance is measured and displayed on the LCD
with the help of the controller.
 The sensor fitted above the antenna with the stepper
motor rotates 180 degrees.

13. ADVANTAGES:
 Detection and destroying of the missile are done
automatically.
 Discrete distance of the object can be detected and
measured.
 It can detected small object over long operating
distances.

14. APPLICATIONS:
 Ship velocity measured.
 Vehicle location.
 Bio mass estimation.
 Echo sounding

15. FUTURE SCOPE:
 1. By using microcontroller we can implement the
intelligent system in future.
 2. In Future it can be used as an advanced tracking
system along with high intensity camera to track a real
target.

16. CONCLUSION:
• This project of missile detection and automatic
destroy system is modified to aim at a missile object in
three-axis rotation by following the Ultrasonic
transceiver data.
