17、a Wide Band technology (UWB), as identified below: Part 1: “Building material analysis and classification applications operating in the frequency band from 2,2 GHz to 8 GHz“; Part 2: “Object discrimination and characterization applications“; Part 3: “Location tracking applications operating in the f

18、requency band from 6 GHz to 9 GHz“; Part 4: “Object identification for surveillance applications“. Introduction Ultra wideband technology enables a new generation of devices for building material analysis and classification of buried objects and material. The non-destructive scanning of building str

19、uctures offers large economical advantage compared to conventional destructive methods. These handheld devices are lightweight and are manually operated at low power. They exhibit a low activity factor during operation. The typical total operational duration is limited to a few minutes as the area o

20、f interest is usually confined to a few m and the measurement results are instantaneously available. Due to the low activity factor, the limited activation time per task, the nature of the applications, random use over time and location of the usage, no aggregation occurs. The devices are designed t

21、o work only in direct contact to the building structure being scanned and are designed to couple the electromagnetic signal directly into the building structure. The devices will not operate without physical contact to the building structure to be investigated. Parasitic, undesired radiation into fr

22、ee space is significantly reduced due to the device design and the additional attenuation of the measured building structure. Equipment features (e.g. deactivation switch, dynamic power control, listen-before-talk) may reduce such radiation even further. Frequencies in the lower GHz range are necess

23、ary to penetrate lossy building materials, such as concrete, because they exhibit a large attenuation which increases with frequency and to minimize clutter. A large bandwidth is required to ensure sufficient measurement resolution, needed for object identification, separation and classification. ET

24、SI ETSI TR 102 495-1 V1.1.1 (2006-01) 5 1 Scope The present document provides information on the intended applications, the technical parameters and the radio spectrum requirements for UWB material analysis and classification devices operating in the frequency band from 2,2 GHz to 8 GHz. It describe

25、s handheld systems that are manually operated to scan a building structure for hidden objects and to analyze building material properties. In addition, the equipment design only supports activation when in direct contact to the structure or material being investigated. It includes necessary informat

26、ion to support the co-operation between ETSI and the Electronic Communications Committee (ECC) of the European Conference of Post and Telecommunications Administrations (CEPT), including: Detailed market information (annex A); Technical information (annex B); Expected compatibility issues (annex C).

42、R Wall Probing Radar 4 Executive summary The present document describes a new generation of devices using Ultra Wide Band Sensor technology for building material analysis and classification applications. These devices are handheld and operated manually. Due to the low activity factor, the limited op

43、eration time per task, the nature of the applications, random use over time and location, it is assumed that no aggregation occurs. In addition, the equipment design only supports operation taking place in direct contact to the structure or material being investigated. In addition, Listen-Before-Tal

44、k (LBT) may be implemented to detect certain other victim devices operating within the same frequency range. The construction and operating conditions of such devices assure very low parasitic, undesired emissions and the number of devices is quite limited. UWB sensor devices operate with very low a

45、ctivity factors. ETSI ETSI TR 102 495-1 V1.1.1 (2006-01) 8 There is evidence that these devices significantly improve maintenance tasks, quality assessments and provide saving potentials. Public safety is enhanced, e.g. for consumer usage by detection of gas pipes or electrical installations or for

46、inspections of large buildings and structures. The main application for the equipment described are social benefit by providing a means to detect salt, water content of bridges and thereby assessing the corrosion state, particularly for consumer and public safety is addressed (unlike professional GP

47、R/WPR does), e.g. by detection of gas pipes or electrical installations. A high bandwidth is required to obtain sufficient spatial resolution. To detect weak targets a minimum power level is necessary. Building materials typically provide a high attenuation for UWB signals of 1 dB/cm or more. This e

48、nsures a low parasitic, undesired transmission of the UWB signals into free space. The close proximity of the device to the building material and the special design of the device ensure low parasitic reflection or radiation into free space. 4.1 Status of the System Reference Document The present doc
