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.
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.
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.
