guard systems

This article is aimed at design and development of the new optimal approaches to analyze and process the reflected signals of guard systems to provide for detection of object’s motion at a high level of reliability and noise robustness. The process wideband signals of guard systems transformation directly in the time-frequency (wavelet) domain has been investigated for various basis functions, decomposition depths, and noise levels, which resulted in the definition of recommendations and principles for selection of the most efficient methods for processing of such signals.
