Abstract

The study of methods of searching for explosive objects is an important problem, as it allows to determine the effectiveness of the application of each of the existing methods, which is extremely important for the safety of civilians who are in war conditions, and also allows to prevent possible terrorist acts.This article examines three main methods: laser Raman spectros-copy, ground-penetrating radar, and the terahertz search method.Laser Raman spectroscopy is one of the rather promising methods for the study of explosive objects.It is based on the analysis of the spectrum of light scattered after illumination with a laser beam.Each substance has its own characteristic scattered spectra that can be used for its identification.Laser Raman spectroscopy is highly specific and sensitive to the chem-ical composition of materials, including explosive substances.It can be applied for non-invasive and rapid detection of such substances, even if they are present in large volumes.GPR is another method for finding explosive objects.It uses radio wave radiation to measure the properties of materials and can detect changes caused by the presence of explosive substances.Ground-penetrating radar has high resolution and the ability to penetrate through different layers of materials, which makes it effective in detecting hidden objects.The use of a terahertz signal is also a promising method in the search for explosive substances.It is based on the use of radiation in the terahertz frequency range, which is between the microwave and infrared ranges.This method is characterized by high sensitivity to chemical changes in materials and the ability to detect even very low concentrations of substances.The use of data processing algorithms and artificial intelligence contributes to the development of effective systems for detecting explosive materials.A summary analysis of the latest research and publications indicates the effectiveness and perspective of the methods of terahertz technology, ground-penetrating radar and laser Raman spectroscopy in the detection of explosive objects.These methods are characterized by high sensitivity, specificity and the ability to work in real time.Additional research and develop-ment of these techniques can contribute to further improvements in security systems by effectively detecting and removing explosive objects to prevent potential hazards.
