LASER FREQUENCY MODULATION TACTICAL TRAINING SYSTEM

摘要

A laser based tactical engagement simulation training system, and in particular a MILES type system, is characterized by an improved communication code structure for the system. The improved code word structure comprises a standard MILES code word that is modified to contain information over and above that required to be embodied in a standard MILES code word. This is accomplished by FM modulating the logic level "1" pulses of the standard MILES code word in a manner that embeds additional information in the word and enhances the system, while at the same time maintaining downward compatibility with existing MILES systems. Apparatus also is provided for encoding, transmitting, receiving, decoding and processing information embodying the improved code structure, which significantly enhances tactical engagement simulation for direct fire force-on-force training, and that yields more accurate simulation to improve tactical training results.
