Abstract: A cascaded impulse convolution shaping method for a nuclear signal includes: obtaining a detector signal by using a detector; convolving the detector signal with a Gaussian signal by using a multistage cascaded shaping system; and performing double-exponential impulse shaping, and generating, by using the multistage cascaded shaping system, a Gaussian-shaped impulse signal with a narrow pulse width for analysis. Based on the characteristic that a multistage cascaded convolution of a complex system can exchange a convolution sequence, the detector signal can first pass through a cascaded inverse system to form an impulse signal, and then the impulse signal is convolved with the Gaussian signal to generate a cascaded impulse convolution signal. This method can be extended to a three-exponential or four-exponential signal for Gaussian, trapezoidal, cyclotron up-scattering process (CUSP), cosine-squared distribution, and Cauchy distribution shaping.
