Nonlinear target recognition

  • US Patent No. 7030808
  • Issued: April 18, 2006
  • Status: Expired

Nonlinear target detection for the detection of extremely weak signals when buried in very high levels of noise is performed with improvement of the quality of the signals received in the data by the amplification of the signal to noise (S/N) ratio. The S/N ratio increases dramatically after the originally measured signal is passed through a nonlinear stochastic resonance filter.
