Abstract

We propose and discuss modified correlation criteria for the detection and identification of dangerous substances using pulsed THz signal in the reflection mode. These criteria are integral criteria in time and they are based on the SDA method. We develop various approaches for enhancement of features of a detecting substance in reflected THz signal under investigation. These criteria are applied for the detection of different explosive situations. Among them we consider a mixture of explosives and PWM C4 explosive with very complicated surface. Proposed algorithms show both high probability of the substance identification and a reliability of realization in practice. We discuss modified correlation criteria for the detection and identification of dangerous substances using pulsed THz signal in the reflection mode.
