Design and implementation of an embedded system to detect military fratricide crisis

摘要

Friendly fire is the situation where military forces attacks on friendly forces while attempting to attack the enemy. Causative reasons may be either misidentifying the target as hostile or due to errors. Such attacks results in unwanted casualties in the battle field. Utilization of improved technology to assist in identifying friendly forces is an ongoing process to prevent any fratricides. In this proposed paper one such attempt is made to develop an embedded device to identify friendly forces. In this approach encrypted data is sent through laser beam for an authentication. Implementation method gives special consideration to power down strategies, efficient encryption and decryption methodologies and theft security for the module. Software programming algorithm and their implementation is also discussed. PIC16F877A from Microchip Corporation is used as heart of this design. It features 256 bytes of EEPROM, self programming, 8 channels of 10-bit analog to digital converter, UART. Using mickroC PRO IDE, entire software programming done in embedded C language.
