In today's world enemy warfare is an important factor of any nation's security.The national security mainly depends on army (ground), navy (sea), air-force (air).The important and vital role is played by the army's artillery such as missile, guns etc.This system come up with an idea of detecting the incoming obstacle whether it is enemy or friendly with the help of higher encryption and decryption routine using wireless module.This system develops ultrasonic based radar system which detects obstacles continuously.To identify obstacle is friend or enemy RC4 algorithm is used which is implemented in ARM7.The main factors in RC4's success over such wide range applications are its speed and simplicity which efficiently implemented in both software and hardware.Ultrasonic based radar model will rotate 360 degree with the help of DC motor.itsend ultrasonic distance transmitter.PC including software to display orientation of obstacle.If obstacle crosses the set range the transmitter will send encrypted frame to incoming unit which acts as receiver over IR transceiver module.If decrypted frame is received from the incoming unit then the obstacle is friend.
