    Abstract
  • To suppress the effects of signal power, distance, and medium attenuation in propagation on the fuze action of underwater weapon, automatic gain control(AGC) is necessary for narrowing the dynamic scope of signal amplitude. We proposed an AGC method based on the number of signal amplitude over threshold, and analyze the principle of signal amplitude detection in this paper. To eliminate the influence of receiver noise on AGC errors, we presented a way to optimize the threshold selection. Application of our method to an underwater acoustic receiver system demonstrates its high control precision and anti-interference performance.
