Paper Abstract

An innovative communication system has been developed. This system has the potential for improved secure communication for covert operations. By modulating data on the chaotic signal used to synchronize two nonlinear systems, we have created a Low Probability of Intercept (LPI) communications system. We derived the equations which govern the system. We made models of the system and performed numerical simulations to test these models. The theoretical and numerical studies of this system have been validated by experiment. A recent design improvement has led to a system that synchronizes at 0 db signal-to-noise ratio. This development holds the promise of a Low Probability of Detection (LPD) system.
