Abstract
We propose new effective criteria for the detection and identification of substances, including explosives. These criteria are integral criteria on time and they are based on the SDA (Spectral Dynamics Analysis) method. We apply these criteria for the detection of explosive in the most difficult cases of the explosive identification. In the first case, we consider the compound explosive. In the second case we consider the complicated shape of the PWM C4 explosive. In all cases we detect and identify the substance. We developed first version of code for real-time identification of substance.
