Short-range ultra-wideband (UWB) radar sensors belong to very promising sensing techniques that have received vast attention recently. The M-sequence UWB sensing techniques for radio detection and ranging feature several advantages over the other short-range radars, inter alia superior integration capabilities. The prerequisite to investigate their capabilities in real scenarios is the existence of physically available hardware, i.e., particular functional system blocks. In this paper, we present three novel blocks of M-sequence UWB radars exploiting application-specific integrated circuit (ASIC) technology. These are the integrated 15th-order M-sequence radar transceiver on one chip, experimental active Electronic Communication Committee (ECC) bandpass filter, and miniature transmitting UWB antenna with an integrated amplifier. All these are custom designs intended for the enhancement of capabilities of an M-sequence-based system family for new UWB short-range sensing applications. The design approaches and verification of the manufactured prototypes by measurements of the realized circuits are presented in this paper. The fine balance on technology capabilities (Fc of roughly 120 GHz) and thoughtful design process of the proposed blocks is the first step toward remarkably minimized devices, e.g., as System on Chip designs, which apparently allow broadening the range of new applications.

In this paper a new method for nondestructive testing (NDT), applied to carbon fiber composite materials, is investigated. The approach is based on the comparison between the electromagnetic signal reflected by the carbon fiber composite sheet under test, when an ultra-wideband (UWB) signal is incident on it, and the one reflected by a healthy sheet. The possible presence of a defect is then revealed by an appropriate metric measuring the mismatch between the two reflected waveforms. The performance of different metrics is investigated, for two defect types, based on real measurements in an indoor environment. As an outcome of our experimental activity, very promising results have been obtained for one of the tested metrics, which allows to accurately detect surface defects with a size comparable to the radar resolution on a carbon fiber composite sheet.

“…In recent years, there has been a relatively large demand for the development of UWB sensor systems. These systems are used in the field of non-destructive testing and in industrial areas [2][3][4][5][6]. In specific applications, UWB sensor systems are used as Ground Penetrating Radar [6,7], to locate and search for people behind obstacles and walls [8,9], to locate general objects or robots [10], in the field of non-invasive diagnostics and detection in medicine [11][12][13], and also in the automotive industry [14].…”

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.
