Intelligent system for radar monitoring of transport communications

Application of Ultra Wide Band radar for monitoring of transport communications is considered. A fundamental peculiarity of UWB radar systems is that the reflected signal carries more information regarding the target shape than the conventional sensor. The number of frequency components in the UWB transmitted signal is large, and different scattering components on the target will not only have different resonant frequencies, but will also, due to their spatial separation on the target, reflect the illuminating short duration UWB signal at different times. Therefore, the UWB signal return is the sum of independent returns spread out discontinuously in time and consists of multiple time-separated scattering matrices, reflecting the separate spatial interactions on the target. This is the basis for the unique ability of target recognition via UWB sensors. An attractive feature of UWB radar's application as a security sensor is its hardware simplicity and, consequently, potentially low cost. In principle, it can be developed in both time and frequency domains. Algorithms used for radar signal processing are based on the data of signal registration. Both direct and inverse problems for radar probing of transport communications are considered in the article.
