GBSAR is a tool which can provide additional protection during the cons

34、truction and maintenance of buildings, bridges, tunnels and monitor environmental structure changes. GBSAR provides high accuracy and outstanding reliability. The objective of designers and operators of GBSAR is to direct radar signals towards the surface of a construction or environment to detect a

35、ny movement or resonance of the object. GBSAR does not communicate any information via the radar signal to any other equipment; therefore no protocol communications standard is required. The GBSAR equipment operates under the Short Range Devices rules of not claiming protection from other radio comm

36、unication services operating in the same or adjacent bands. Recognizing that GBSAR may have indirect safety of human life implications, manufacturers should pay particular attention to the potential for interference when selecting parameters for GBSAR. 4.1 Status of the present document Version, V 1

37、.0.0_0.1.1, of the TR was approved by ERM-TG28#14 and was submitted to WG ERM-RM for approval via correspondence. Comments were received from the NL and CH administrations. These comments were dealt with in version V 1.1.1_1.2.1 of the document, which was forwarded to CEPT . In order to take into ac

38、count further comments, including those received during the meeting of WG FM of CEPT (September 2006), a new version (1.1.1_1.2.2) was produced. The present version is offered to TC-ERM in view of its approval as TR 102 522 and its publication. 4.2 Market information Interferometric analysis and Syn

39、thetic Aperture Radar (SAR) synthesis are two powerful data processing techniques which have nowadays been used for airborne and space-borne remote sensing systems with the objective of detecting ground displacement. These two techniques, based on processing of data acquired by electromagnetic micro

40、waves reflected by targets, can be exploited by Ground Based (GB) system (in the following named GBSAR system) to perform: Structures monitoring. Terrain monitoring. The deployment of the system is up to 0,6 and 6 units/1 000 km2for structure and terrain monitoring respectively. For detailed market

41、information, see annex A. 4.3 Technical system description A GBSAR system exploits, as earth monitoring satellites, interferometric analysis and Synthetic Aperture Radar (SAR) techniques to provide displacement maps for terrain or structure monitoring applications. In particular: the interferometric

42、 technique provides data on object displacement by comparing phase information, collected in different time periods, of reflected waves from the object, providing a measure of the displacement with an accuracy of less than 1 mm; the Synthetic Aperture Radar (SAR) technique enables the system to prov

43、ide high resolution images. High range resolution is obtained using large transmitted bandwidth whereas high cross range resolution is derived, only for the terrain monitoring applications, exploiting the movement of the physical antenna along a straight trajectory. ETSI ETSI TR 102 522 V1.1.1 (2006

44、-12) 9 The GBSAR system is based on a Step Frequency - Continuous Wave (SF-CW) coherent radar that transmits, step by step, continuous waves at discrete frequency values in a frequency range of bandwidth B. By this method an interference mitigation is offered as the transmission is only on for a sho

45、rt time at each discrete frequency. It is important to observe that the transmitted signal is a sequence of non-modulated frequency steps, whose total frequency range (bandwidth) is controlled by the equipment management system. The bandwidth can be adjusted between 100 MHz and 200 MHz when required

46、 by the measurement. For detailed technical information on GBSAR, see clause B. 5 Current regulations There is currently no regulation for GBSAR in the frequency range 17,1 GHz to 17,3 GHz. The current annex 6 (“Equipment for Detecting Movement and Equipment for Alert“) of CEPT/ERC Recommendation 70

47、-03 1 contains provisions for operation in the following bands: 24,05 GHz to 24,25 GHz at a power level of 100 mW. 13,4 GHz to 14,0 GHz at a power level of 25 mW. However, these power levels are insufficient to permit the operation of GBSAR capable of providing the range resolution and displacement

48、accuracy necessary to provide industrial users of GBSAR with the capability they require. An assessment of these alternative bands (13 GHz and 24 GHz) is given in clause B.2.1. It has to be noted that although the frequency range 16,6 to 17,1 GHz is allocated to RADIOLOCATION designated as Military

49、Harmonized band for land, airborne and naval radars, the following range 17,1 to 17,3 GHz is allocated to RADIOLOCATION as a designated band for military radars shared with civil uses in accordance with the provisions in the European Common Allocation Table. 6 Proposed regulations It is proposed to permit GBSAR to operate with the specifications in table 1.
