Under the new IMO performance standards relating to the shipboard radar equipment, all of them shall now be capable of displaying the AIS information; the term ARPA, in term, is planned to be replaced with the TTD, standing for the target tracking device. Nowadays, a broad range of such devices is available, and the personnel involved in operation of this equipment, shall be provided with the familiarization training at the time of the boarding, and such training shall be equipment-specific.
The present booklet shall accompany this video training film and is mainly intended to be used by the navigation officers to train the cadets and also to be used by all other people on board to get familiarized with the main issues related to the target tracking as applied to the collision avoidance. Maritime radars enable the vessels to pinpoint other ships and to locate the own position of the vessel relative to the landmarks.
The working principle of the radar consists of sending the beam radio wave pulses and amplification, processing and further displaying of the returning echoes - this allows the radio operator to "see" the ships which would normally not be visible due to the mist of fog, or lack of lighting. It shall be noted that the echoes from some targets may not be strong enough and therefore not display while other objects may be obscured...
Marine radar is considered a must-have piece of shipboard radio equipment necessary for the safe navigation of the vessels; such radars are also carried even by many leisure crafts on voluntary basis, with VTS, standing for the vessel traffic services, and this equipment is truly indispensable to the safe and effective operation of the major marine ports and harbors; in addition, this equipment has some other important maritime applications.
The present volume will tell the readers how marine radars detect the targets. The content starts with quite brief historical overview to explain the way contemporary practice has developed from the original faltering steps of the past times. The authors have described and illustrated the modern marine radars together with both active and passive beacon targets.
As we know and as it has been discussed in this publication by Videotel, operation of the marine radar relies on the ability of various marine objects to return the echoes, and the authors have examined subject ability in theoretical and practical standpoints. The have also included the full technical analysis of numerous real life factors such as the environment and the weather plus the radio operator's ability to set the required controls. All efforts have been made to be comprehensive and to minimize the need for any other references.
The aim of this technical study is provision of the specific and thorough analysis of all opportunities and of the legal/economic feasibility of implementing the safety due of the navigation, considered a transit charge that should be paid as necessary by all vessels that cross the waters of the coastal States, another aim of the compilers of the publication is to perform a professional estimation of the real contribution of such device to improving the capacities of subject countries in the surveillance of marine navigation, following the decisions of the GTMO 5+5 Ministers.
Among the purposes of this document we would definitely highlights the diagnosis of the systems of the navigation aids, analysis of the real needs (particularly funding needs), operational approaches and legal provisions, and also the possible implementations of the due for the vessels and coastal States, elaboration etc. Six major parts of this study are providing industry with virtually all required info relating to the international legal framework and legal feasibility, services required means/costs, characterization of the due, elements of the benchmark, and impacts. The annexes will provide the terms of reference, the questionnaire plus the actual status of the conventions, as adopted by the GTMO 5+5 members.
The main aim of Ashley Waite, the practicing engineer and author of this excellent and very useful volume, was to provide all other practicing engineers with the source of information that would help them to understand the fundamental working principles of sonars and also to let them develop the formulas and so-called rules of thumb for the design and performance analysis of subject equipment.
Having a remarkably long professional experience in design and operation of sonars, the author has managed to use this knowledge providing a good practical guidance and working solutions to the various problems most commonly encountered by the technicians and engineers involved in design and operation of the sonars as well as in the performance analysis. The content is arranged in three main parts covering the parameters of the equipment, sound propagation through the sea water and practical sonar systems.
The book is covering all important aspects of sonars and contains numerous useful working examples. The readers are not expected to have any serious knowledge of sonars because the way of explanation is very clear and easily understandable even to the beginners, with no math or physics background required. The end-chapter exercises provided with the correct solutions have been included for the self-assessment and tracking of the training process. The book will be an excellent addition to every engineer's library.
The last years have shown significantly increasing attention paid to the MTS, i.e. maritime transportation systems; the industry focused on efficiency and safety of sea transportation, prevention of potential pollution caused to the environment from ships and also response to the cases of pollution.
The AIS, standing for the auto-identification systems, were originally developed to be a response to all above mentioned concerns, and huge work attempting to define the technical/communication requirements applying to such systems. Those efforts have finally resulted in development of the worldwide carriage requirements for the systems aboard all ships as per the SOLAS Convention, as necessary.
The present report addresses the shipboard display of the information. Considering insufficient amount of the recognized standards and requirements applicable to such display, the USCG did request NRC to examine both technical and human factors. The efforts were made to include proper assessment of the current AIS technologies together with the evaluation of the system designs and capabilities. The committee was originally expected to consider the potential impacts of the changes in the technology, economics, security plus various operational considerations plus human factors, operational environments, technical integration, international standards and other relevant matters...
The main content of the present training course was developed under the RoNoMar standing for the "Romanian-Norwegian Maritime Project" and starts with a Glossary of terms/abbreviations used within the publication and industry in general. Radio is considered a basis of all safety and distress systems that are in wide use by the vessels at sea since the initial instance of application of the radio-technology to save the human lives at sea back in 1899.
The radio technology has soon been realized to be very effective and the distress-and-safety system based on the radiotechnology was established in the internationally recognized regulations and rules governing the types of the equipment and frequencies used, together with the established operational procedures.
The book starts with the introduction and theoretical basics of the GMDSS system, followed with the propagation of the radio waves, receivers and transmitters of the waves, safety and distress communications, telex procedures, DSC, radiotelephony and Inmarsat, MSI, terrestrial distress communications, SART, EPIRB, power supplies and general radio-related regulations, traffic charging and antennas, GMDSS frequencies and some additional reference information related to the operators and access codes, antenna positioning etc.
This is the informative handbook with the content initially aimed to serve as the accessible practical guide for use by the shipboard radio operators as well as shore-based radio stations, particularly operators of the VHF and SSB, i.e. MF/HF radios. It will provide all readers with the required technical info about the radiotelephony procedures, coverage and appropriate use of the cell phones, terms and contacts, and how exactly SAR is being managed in New Zealand.
The information presented in the handbook has been arranged in five major chapters. The first one has been dedicated solely to the radiotelephony procedures including prowords, i.e. procedural words, VHF channels, SSB frequencies, silence period etc., while the second one addresses the coverage and services including broadcasts and warnings, medical advice, sat safety services etc.
The third chapter provides other important information including the medical evacuation, working with choppers, transmissions in harbor, testing the radios, sea rescue by choppers etc. Two remaining chapters of this handbook are providing the useful contacts plus contain a small yet comprehensive Glossary of the terms used in this handbook and generally in the industry.
We definitely recommend you to have a look in the revised and significantly expanded "Radar Handbook" providing students of the maritime colleges, professionals and enthusiasts of radio technology with a required coverage of the associated technology starting right from the theoretical fundamentals and up to the newest contemporary applications of radars.
The content was worked out basing on the invaluable contributions by thirty world recognized experts in the subject field, and their combined professional efforts eventually result in this title expected to serve as a good information source addressing the radar subsystems, e.g. the antennas/receivers, transmitters, pulse compression, processing of the data etc. The target cross-section is also explained, with the various radar systems, echoes from sea and ground, etc.
This release features the truly unsurpassed guidance on the theoretical concepts, practical applications of the radars, and several completely new chapters covering the signal processing, traffic control, bistatic radars, sea clutter, meteorological radar, ground penetration, auto-detection, sensor integration etc. Hundreds of the clear and informative illustrations plus the real-life examples are supplementing the text of the volume, included to facilitate better understanding.
