Automatic Defence and destroy system with RADAR using Ultrasonic sensor

Description

Abstract

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 direction 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.

War is an organized armed conflict that is carried out by states, nations, national and social groups. This ultrasonic proximity detector comprising independent, battery or AC powered Wi-Fi 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 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 8051 microcontroller receives the signal from ultrasonic receiver it activates the missile 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.

The ultrasonic proximity detector comprising independent, battery or AC powered transmitter and receiver sections make use of a pair of matched ultrasonic piezo ceramic transducers each operating at around 40 kHz each. This circuit is used to get reflected signals of 40 KHz from the object (here a missile) to feed that to a program to the microcontroller.

Op-Amps are used for amplification of the weak signals received upon reflection from the obstacle (which is inbuilt in ultrasonic module), by the receiving ultrasonic transducer sent by the transmitting one, to switch on appropriate load while the program is executed at the microcontroller end.
