Title:
IDENTIFICATION OF EXPLOSIVES BY FREQUENCY DOMAIN MICROWAVE SPECTROSCOPY IN REFLECTION MODE
Document Type and Number:
WIPO Patent Application WO2006031155
Kind Code:
A3
Abstract:
The invention lies in explosives detection and identification method, which allows using it in mobile devices intended for use at locations, where crowds of people gather, and in various closed spaces. Said method includes the exposure of the object being checked with a pulse in the frequency range from 300 MHz to 150 GHz, reception of the signal reflected from the object measurement of the phase shift of the received signal vs. the emitted signal and its intensity, which is used to determine the absorption ratio of the object, comparison of the measured phase shift with a reference phase shifts recorded in advance, which correspond to certain types of explosives. The results of the comparison, taking into account said absorption ration are used to determine the presence of an explosive and its type. The pulse is generated in the form of a pulse burst sequence with varying frequency.
