Abstract

Aiming to the noise effect on weak signal extraction in the laser off-axis scattering detection, the signal processing technique, which applies the stochastic resonance that when the stochastic resonance among input signal, noise and nonlinear system is reached the output signal noise rate (SNR) is improved by converting the power of noise into the signal, is put forward. On the adaptive stochastic resonance theory, the new algorithm combining the genetics algorithm and adaptive resonance algorithm, which is optimized by applying niche technique and 'cross generational elitist selection' strategy. Meanwhile, the concrete realization description and stimulation are made out. It shows that the weak can be well detected from the low SNR circumstance, and the new method by that in the laser off-axis scattering detection the noise effect on weak signal extraction is weakened, is found. The method is promising in the applications such as laser alarm.
