Printedonacid-freepaper ThisSpringerimprintispublishedbytheregisteredcompanySpringerInternationalPublishingAG partofSpringerNature Theregisteredcompanyaddressis:Gewerbestrasse11,6330Cham,Switzerland Preface At present, we observe the exciting modernization of wireless technologies: the radio communication and radio broadcasting systems, the television systems, and the wireless data transmission. This modernization is directed to increasing of capacity, spectral efficiency, noise immunity, and it is performed on the base of complex modulation types with code and time division, ultra-wideband signals, adaptation to the environment, redistribution and reuse of radio frequencies, etc. Inthecivilarea,theDVB-T2digitaltelevisionsystemsofthesecondgeneration are replacing now the previous first-generation DVB-T digital systems. The second-generation system provides increasing of information transmission rate up to30%asminimum.Insteadoflocalwirelessaccesssystemsofthea,b,g,nWi-Fi standards, the systems of the ac standard arewidely used withthe capacity, which value is more in order. In cellular communication networks, the LTE technology has got wide distribution, which has significant advantages compared to the pre- vious UMTS technology. In the military area, the fast development of wireless communications and control technologies is observed. The conception of modern war assumes the system usage of the military equipment and armaments integrated in the unified stable information network, which should ensure delivering of the reliable and complete information about situation and orders of headquarters to all participants inrealtime.Systemsofwirelesstelecommunications,whichareusedatallcontrol levels beginning from the tactical unit and finishing at the strategic level, are concerned as key elements of the military information network. Methods of radio monitoring should be improved after its object variation. To them, we can relate the combined electromagnetic situation, including the occu- pancy of radio ranges and frequencies, the acting radio electronic equipment, the high-frequency industrial, medical and scientific installations, the sources of industrial interferences. In order to manage with the growing stream of more complicated tasks without increasing of the employees’ quantity, the modern automatedcontrolsystemsshouldbeused.Applicationofsimilarsystemsincreases rate and accuracy of radio monitoring tasks fulfillment, releases the operating personnel from routine jobs, and essentially increases the labor productivity. v vi Preface The Russian IRCOS Company works at Russian and international markets during 25 years. For a quarter of a century, this company made a way from the development and delivery of the radio monitoring equipment with limited func- tionalityonthebaseofimported radioreceivers uptothemodernmulti-functional high-performance equipment of the own manufacture and the automated radio monitoring systems. This equipment integrates both the equipment of the own production and the equipment of other companies-manufacturers. The automated systems delivered during more than five last years are intended for application in thecivilandmilitaryagencies,theyprovideautomaticplannedandoperativemodes under the operator control and use the risk-oriented eventual mechanisms of functioning, and they are able to operate effectively at district, regional, and national levels. Thisbookwidensthematerialsofbooks“RadioMonitoring:Problems,Methods and Equipment. Springer Lecture Notes in Electrical Engineering 2009” and it is based on the new research results of the automated radio monitoring systems development, obtained by radio and electronic engineers, experts in the software and researchers of the IRCOS Company. That includes constructions and features of radio monitoring equipment, architectures of the software, methods and pro- cessing algorithms for radio signals, which purpose are search and detection of radio emissions, measurement of their parameters, identification of radio emission sources and their localization in the open territory and inside the rooms. In Chap. 1, the architecture of the automated systems is considered, which are purposedtobeusedatnational,regionalanddistrictlevelsbythecivilandmilitary agencies. The features of automation units are described, which consist of the radio monitoring equipment, the engineering-technical infrastructure, and the complex of software packets. The examples of the ARMADA and ASU RCHS “Universiada-2013” automated systems constructions are given. Chapter2isdevotedtomethodsofrevelationofunauthorizedradioemissionsin the engineering objects, in the rooms, in the open territory. The sources of unau- thorized emissions are considered, the stages of their revelation, the equipment for radio monitoring to be used; the examples of the AREAL automated system con- struction are given depending on application conditions: along the lengthy boundary, in the restricted part of the open territory, within the limits of the completely closed territory, in rooms, etc. Some typical variants of the system construction are described. Chapter 3 is devoted to the software architecture, which controls the automated system functioning. The software unifies the geographically distributed equipment of radio monitoring, provides users interaction with equipment on the base of the risk-oriented eventual mechanism and centralized data storage, automatically con- trols the system status, forms the accounting and report documentation, and interacts with external informational systems. Chapter 4 contains information on engineering infrastructure of the automated systems. The arrangement of control centers and points, radio monitoring points, applicationofcommunicationlinesbetweenthenodesoftheautomatedsystemare discussed. Preface vii Chapter 5 considers components of the automated systems, which provide the radio monitoring functions fulfillment: digital radio receivers (DRR), automated radio direction-finders, and manpack radio monitoring equipment including their construction and methods for signal processing. InChap.6,measuringmethodsforradiosignalparametersarediscussed,which are necessary to control frequency-spatial plans of the radio communications ser- vice: the central frequency of analog and digital signals, the width of occupied frequency band, the electromagnetic field strength, the radio interference intensity, as well as the occupancy of the radio frequency spectrum. In Chap. 7, on the base of the general approach to goniometric, amplitude, temporal, frequency, and time difference of arrival methods of measurements, the algorithms of radio emission sources localization are synthesized. Examples of constructions of time difference of arrival systems are given, and algorithms for synchronization of radio receivers included in the systems are examined, which is necessary for radio emission sources location calculation with high accuracy. Chapter 8 is devoted to TV and radio broadcasting signals monitoring. The peculiaritiesofdigitalTVsignalstechnology,theanalyzerofdigitalTVsignalsare described as well as the automated complex for multi-channel monitoring of the broadcast content. In Chap. 9, the reader will be acquainted with problems of construction and functioning of the set of radio signal analyzers for digital communication and data transmission technology including GSM, UMTS, LTE, DMR, APCO P25, Wi-Fi technologies,whichusethedigitalradioreceiversoftheARGAMAK-familyasthe basing equipment, which provide a possibility of radio signal analysis both at the standard and non-standard frequencies.
