Weak Signal Detection Using Chaotic Phase Transition

This study investigates the theory and simulation experiments of weak signal detection through chaotic phase transitions. After analyzing the weak signal detection method based on oscillator initial value sensitivity, we identified that transient processes affect detection performance. We propose a guessing game algorithm as an improved detection approach, with research on simulation input noise generation and step size selection to establish a simulation model. The method detects weak sinusoidal signals under typical noise backgrounds, with experimental results demonstrating...
