The UWB Radar Application in the Aviation Security Systems

Abstract

In the process of our research, we have identified new methods of processing ultra-wide-band (UWB) radar signals and possibilities of the UWB radar use in aviation security systems. We paid our main attention to finding new algorithms for tracking the movement of a person behind an obstacle using the UWB radar. Such UWB radar application is typical for tracking the movement of people behind obstacles in case of security forces intervention at an airport. In the research process, we used methods of analysis, synthesis, and measured data from the performed experiment. The main contribution of the paper is the development of new algorithms for locating the movement of a person behind an obstacle using a straight- line method in the case of using two independent UWB radar systems. The article did not examine the accuracy of determining the position of a person behind the obstacle. We found that when applying the Kalman filter after signal processing by the straight-line method, the trajectory of the person’s movement behind the obstacle was smoother. The results of processing the measurement signals of UWB radar by the linear method have shown that this method is applicable to tracking a person behind an obstacle and can be used in aviation security systems.

Sinuous Antenna for UWB Radar Applications

“…Hardware components of UWB radars were presented in [ 23 ]. In [ 24 ], the authors identified new methods of processing UWB radar signals and possibilities of the UWB radar use in aviation security systems. The authors of [ 25 ] present a conceptual guide to the UWB impulse signal and target interaction phenomenon showing how to use the signal spectrum change to identify and enhance detection and tracking of certain target classes.…”

Risk Management Level Determinants in Visegrad Countries – Sectoral Analysis

“…Although SMEs are aware of the existence of business risk, they perceive it with different intensity (Bartos et al, 2021). Many companies use mainly informal risk assessment (Antosko et al, 2015;Petruf et al, 2015), although in technological processes, increasingly more sophisticated system and predictive mechanisms are implemented (Főző et al, 2019;Kužma et al, 2016;Džunda et al, 2021). Moreover, some companies do not have the appropriate organisational condi-tions for the functioning of a department responsible for the analysis and risk management (Machova & Vochozka, 2019).…”

An imaging algorithm research for the airborne ultra-wideband synthetic aperture radar

“…Literature [1] studied the related technologies of Ultra-wideband radar imaging, and gave the key problems and solutions of Ultra-wideband radar imaging. Literature [2] studied and discussed the application of Ultra-wideband radar in aviation safety system. Literature [3] proposed an improved target recognition algorithm based on carrier-free Ultrawideband radar to improve the target recognition effect of Ultra-wideband radar.…”
