Application of chaotic theory to balise signal detection

Concerning the difficulty of balise uplink signal detection in strong noise density, chaos oscillator system is proposed to detect balise uplink signal, based on the chaos system for its immunity to noise. By combining with the principle of Duffing system used in weak signal detection and uplink signal feature, the methods and steps of using Duffing oscillator to detect the balise uplink signal are proposed, and the simulation model is built to test. Simulation results show that the proposed method of detecting the balise uplink signal using Duffing oscillator is possible, which means that it has good anti-noise performance.
