Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). Introduction The present document covers Pulse and FMCW tank level probing radar a

15、pplications in the gigahertz range, based on SRD technologies, with potential benefits for a wide range of applications such as process control, custody transfer measurement, safety (e.g. to prevent spilling) and industrial applications. The purpose of producing the present document is to lay a foun

16、dation for industry to quickly bring innovative and useful products to the market while avoiding any harmful interference with other services and equipment. The emphasis in the present document is on commercial use of Tank Level Probing Radars (TLPRs). TLPRs, in the scope of the present document, op

17、erate only when installed in closed (not open) metallic tanks or reinforced concrete tanks, or similar enclosure structures made of comparable attenuating material. This operational constraint ensures that the emissions outside of the tanks or enclosure structures do not exceed very low, defined lim

18、its (even less than spurious emissions), for the purpose of determining the fill level of the contents of such tanks. Commercial TLPR applications using pulse RF or FMCW technology within the scope of the present document typically operate or are foreseen in the following frequency bands: 4,5 GHz to

19、 7 GHz; 8,5 GHz to 11,5 GHz; 24,05 GHz to 27 GHz; 57 GHz to 64 GHz; and 75 GHz to 85 GHz. The present document includes necessary information to support the co-operation under the MoU between ETSI and the Electronic Communications Committee (ECC) of the European Conference of Post and Telecommunicat

20、ions Administrations (CEPT) for amending the ERC Recommendation 70-03, annex 6 1. ETSI ETSI TR 102 347 V1.1.2 (2005-01) 5 1 Scope The present document provides information on the intended applications, the technical parameters and the radio spectrum requirements for TLPR based on e.g. pulse RF or FM

21、CW, operating specifically in the frequency bands: 4,5 GHz to 7 GHz; 8,5 GHz to 11,5 GHz; 24,05 GHz to 27 GHz; 57 GHz to 64 GHz; and 75 GHz to 85 GHz. The present document describes pulse RF and FMCW systems that are used in tank level measurement applications. The scope is limited to radars operate

22、d as short range devices (because of their commercial usage and design), in which the TLPR is installed in closed (not open) metallic tanks or reinforced concrete tanks, or similar enclosure structures made of comparable attenuating material, holding a substance, liquid or powder, whose level is a v

23、ariable. It does not include any radar systems in applications where they would be operated outside closed (not open) metallic tank or reinforced concrete tank, or similar enclosure structure made of comparable attenuating material. The radar applications in the present document are not intended for

24、 communications purposes. Their intended usage excludes any intended radiation into free space which sets it apart from any type of communications equipment. Additional information is given in the following annexes: annex A: Detailed market information; annex B: Technical information; annex C: Expec

31、ference Document TLPR Tank Level Probing Radar 4 Executive summary The present document provides a basis for a general, non-individual, licence-exempt arrangement for tank level probing radar (TLPR) systems. TLPR will play a pivotal role in the economic direction of major mass material storage infra

32、structure projects. TLPRs provide high accuracy and outstanding reliability, high resistance to dirt and tank atmosphere, regardless of the substance in the tank, its temperature or pressure, allowing precise control of manufacturing processes and storage facilities. The objective of designers and o

33、perators of TLPRs is to direct signals from the tank top towards the surface of a substance contained in a closed (not open) metallic tank or reinforced concrete tank, or similar enclosure structure made of comparable attenuating material, such that only extremely low unwanted emissions occur outsid

34、e the tank (limits described in annex B). The applications where TLPRs operate, e.g. tanks containing internal structures, etc. demand a relatively high bandwidth and/or power to provide sufficient distance resolution between the surface echo and other disturbing echoes. In either case the shielding

35、 provided by the tank, the absorption of RF energy by the substance in the tank, and the orientation of the antenna to point in a downward direction will act to contain the RF energy radiated from the TLPR to levels that are well below the limits prescribed in existing EMC standards. Given the simil

36、arity in bandwidth to unintentionally radiated digital device emissions and the desire to limit electromagnetic radiation in general, the present document proposes that a general EMC standard should be used to specify the radiation from tank level probing radar systems as measured outside of the enc

37、losure, in which the radar is installed coupled with technical specifications for power output, spurious emissions, duty cycle and antenna gain. This essentially would provide a regulatory structure that ensures these systems do not become sources of radiation that will cause any interference to exi

38、sting primary or secondary services in the requested band. TLPRs do not communicate any information via the radar signal to any other equipment; therefore no protocol communications standard is required for these systems. Market and technical information including the required spectrum, and a discus

39、sion of compatibility issues are presented in the annexes of the present document. ETSI ETSI TR 102 347 V1.1.2 (2005-01) 7 4.1 Status of the present document The draft version, V 0.0.1, was approved by ERM-TG31A and was presented to ERM-RM for discussion and approval at its #28 meeting in Montegrott

40、o. The draft version V1.1.1_1.1.1 is the outcome of the discussion within ERM-RM#28. Version 1.1.1_1.1.2 incorporates minor editorials and has been forwarded to CEPT as a first phase SRDoc for immediate consideration. ERM-RM informed CEPT that the information on the 24,05 GHz to 27 GHz is stable, an

41、d that ERM-RM aims at providing CEPT, very rapidly, a more complete version of the document (expected to cover also the additional frequency bands to be considered for TLPRs). Version 1.1.1_1.2.1 includes the additional frequency bands and other information required by CEPT. It was approved by ERM-T

42、G31A . Version 1.1.1_1.2.2 was circulated for approval by correspondence within ERM-RM until 19 October 2004. The present document V1.1.1_1.2.3 has been approved by ERM-RM and is submitted to ERM#24 for approval for publication. It will be sent to the CEPT for consideration. Version 1.1.2 has been p

43、ublished correcting editorial errors. Nortel Networks (Europe) expressed concern during ERM#24 regarding the inclusion of the 5,8GHz band in this SRDoc. This band is currently the subject of work on a candidate harmonized standard in ETSI EP BRAN covering FWA (including Mesh) equipment. Whilst it is

44、 noted that these tank level gauges are intended for use (mostly) in metallic containers, this restriction in their usage is not mandatory. Nortel Networks (Europe)s concern surrounds the potential increase in the noise floor in the 5,8 GHz band together with the potential impact of these systems on

45、 the sharing studies currently nearing completion in SE38 should their use not be restricted to sealed metallic containers. 4.2 Market information For detailed market information, see annex A. 4.3 Technical system description For detailed technical information on tank level probing radars, see annex

46、 B. 5 Current regulations The current regulations in annex 6 (“Equipment for Detecting Movement and Equipment for Alert“) of CEPT/ERC Recommendation 70-03 1 contain provisions for operation in the band from 24,05 GHz to 24,25 GHz at a power level of 100 mW. However, this bandwidth is insufficient to

47、 permit the operation of TLPRs capable of providing the range resolution and accuracy necessary to provide industrial users of TLPRs with the capability they have requested. Article No. 4.4 of the Radio Regulations 2 has been relied upon by national administrations (and CEPT as well) in many context

48、s to authorize applications not conforming to the Table of Frequency Allocations in the Radio Regulations (e.g. Short Range Devices which are operated in ISM frequency bands). TLPR equipment, as described in this document, might also be operated under Article Radio Regulations No. 4.4. Further, it s

49、hould be noted that ITU-R Recommendation SM.1538-1 3 recommends that national spectrum authorities consider permitting the following bands for TLPRs: 4,5 GHz to 7 GHz; 8,5 GHz to 11,5 GHz; 24,05 GHz to 27 GHz; 57 GHz to 64 GHz (within annex 1, “Additional applications“ in ITU-R Recommendation SM. 1538-1 3); 76 GHz to 78 GHz. ETSI ETSI TR 102 347 V1.1.2 (2005-01) 8 NOTE: The frequencies 0,5 GHz to 3 GHz are recommended for TLPR in Recommendation ITU-R Recommendation SM.1538-1 3 but are not stated here because industry repre
