Description
Summary:Identification of nuclear pulse signal is ofimportance in radioactive measurements, especially inrecognizing adjacent overlapping nuclear pulses. In thisarticle, we propose an estimation method for parameters oftypical overlapping nuclear pulse signals. First, the nuclearpulses are regarded as individual genes and the norm is setas the fitness function. Second, the global optimal solutionis found by searching the population of genetic algorithm,so as to estimate the parameters of nuclear pulse. With highprecision, this method can identify parameters of overlappingnuclear pulses in the Sallen-Key Gaussian signaldecomposition experiments. This pulse recognition methodis of great significance to improve the precision ofradioactive measurement and is suitable for serious overlapof nuclear pluses.
