Radar Technology

In this book “Radar Technology”, the chapters are divided into four main topic areas: Topic area 1: “Radar Systems” consists of chapters which treat whole radar systems, environment and target functional chain. Topic area 2: “Radar Applications” shows various applications of radar systems, including meteorological radars, ground penetrating radars and glaciology. Topic area 3: “Radar Functional Chain and Signal Processing” describes several aspects of the radar signal processing. From parameter extraction, target detection over tracking and classification technologies. Topic area 4: “Radar Subsystems and Components” consists of design technology of radar subsystem components like antenna design or waveform design

Late time response analysis in UWB radar for concealed weapon detection : feasibility study

Remote detection of body-worn concealed weapons or explosives (CWE) is a field of ongoing research. In this Thesis the feasibility of CWE detection by using the UWB radar is explored. The CWE detection is based on the analysis of the Late Time Response (LTR) of the human which has been illuminated by the UWB signal. A specific set of LTR parameters characterizes the target signature. Therefore the existence of a CWE attached on the human body will influence the LTR characteristics and give the composite object i.e. human-CWE a different signature than the simple object i.e. human. The CWE detection methodology is verified by theoretical analysis, modelling and extensive laboratory experimentation. Investigation of the way the LTR parameters are influenced by the existence of the CWE signifies the differences of the LTR signature between the human and human-CWE. So the resolution of the differences in the LTR of a human with and without a CWE as the main objective of the research, are presented in the Thesis. The results verify that CWE detection with the use of LTR is feasible under the experimental conditions presented. Furthermore consideration of all possible detection scenarios is out of the scope of this Thesis.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

SATELLITE AUTOMATIC IDENTIFICATION SYSTEM

Sustav za automatsku identifikaciju (engl. Automatic Identification System - AIS) koristi se kao pomoćno sredstvo u vođenju navigacije. Safety of Life at Sea (SOLAS) konvencijom propisano je da svi brodovi preko 300 bruto registarskih tona u međunarodnoj plovidbi moraju biti opremljeni AIS uređajem. Podatci se u sustavu šalju preko radiofrekvencija. Sustav brodovima omogućava preciznu identifikaciju radarskih ciljeva, identifikaciju drugih plovila i smanjuje potrebu glasovnih komunikacija. Vlastima sustav omogućuje lakše potvrđivanje brodskih zapisa i provođenje propisa. Korištenjem satelita za primanje AIS signala omogućilo se pristupanje podataka sa brodova i ostalih objekata opremljenih AIS primopredajnicima. Sustav je još uvijek u razvoju, unatoč velikim naprecima. Primjene sustava su raznovrsne, ali zbog trenutne korisnosti, primjena u praksi još nije na visokoj razini. U radu se opisuju svi dijelovi satelitskog i zemaljskog sustava, njegov razvoj i uporaba u pomorstvu, te razmatranja o budućnosti sustava.The Automatic Identification System (AIS) is used as an aid in navigation. The Safety of Life at Sea Convention (SOLAS) stipulates that all ships over 300 gross tonnage tonnes in international navigation must have an AIS device. Data is transmitted over the radio frequencies. The ship system enables precise identification of radar targets, identification of other vessels and reduces the need for voice communications. The system enables authorities an easier validation of ship records and implementation of regulations. The use of satellite to receive AIS signals enabled access to data from ships and other facilities equipped with AIS transmitters. The system is still under development, despite great advancements. System applications are diverse, but due to current capabilities implementation in practice is not yet high. The paper describes all parts of the satellite and terrestrial systems, their development and use in navigation, and considerations of the future of the system
