Introduction The request for harmonized European spectrum for tank level probing radars (TLPR) as defined in TR 102 347 4 has resulted in an
17、 addition of identified frequencies for TLPR in CEPT/ERC Recommendation 70-03 1, annex 6. ETSI, in parallel, has published the Harmonized European Standard EN 302 372 2 for TLPR. ITU-R Recommendation SM.1538 3 also covers TLPR. The present document covers the request for harmonized European spectrum
18、 for Level Probing Radar-sensors (LPR) applications not installed in closed metallic or similar (e.g. concrete) enclosure structures. LPR use a similar technology as TLPR, however due to the different installation conditions, different technical requirements are envisaged for the Harmonized Standard
19、. Commercially, sales of LPR are currently limited due to lack of a Harmonized Standard and regulation. License exempt European harmonized conditions for the availability and use of radio spectrum for LPR could lead to an increase of the total addressable market for TLPR and LPR applications. NOTE:
20、From a regulatory point of view, TLPR may not be considered a subset of LPR. Since the majority of radar level sensor products currently on the market are TLPR, and LPR is closely technology related, TLPR are mentioned in the present document mainly for marketing clarifications (see annex A).

ETSI ETSI TR 102 601 V1.1.1 (2007-12) 6 1 Scope The
24、 present document provides information on the intended applications, the technical parameters and the radio spectrum requirements for LPR proposed to be operated in one or more of the following frequency bands: 6,0 GHz to 8,5 GHz; 24,05 GHz to 26,5 GHz; 57 GHz to 64 GHz; and 75 GHz to 85 GHz. LPR co
25、vered by the present document are always installed in a fixed position and pointing downwards to achieve maximum reflection. They use highly directive antennas and the antenna footprint can be defined accurately, i.e. the area of their emissions is well defined, and any reflections outside of the ar
26、ea can be controlled to not exceed a maximum limit by using Adaptive Power Control (APC). The present document describes LPR devices that measure substance levels via short ranges with an accuracy in the millimeter range. LPR use carrier-based Ultra Wide Band technology for this purpose. The present
27、 document provides information to aid in the development of general, non-individual, preferably licence exempt European harmonized conditions for the availability and use of radio spectrum for level probing radar (LPR) sensor systems. Additional information is given in the following annexes: Annex A
28、: Detailed market information; Annex B: Detailed technical information; Annex C: Expected sharing and compatibility issues. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

44、t after the ETSI ERM correspondence approval procedure. 5 Executive summary 5.1 Background information LPRs are used in many industries concerned with process control to measure the amount of various substances (mostly liquids or granulates). LPRs are used for a wide range of applications such as pr
45、ocess control, custody transfer measurement (government legal measurements), water and other liquid monitoring, spilling prevention and other industrial applications. The main purposes of using LPRs are: to increase reliability by preventing accidents; to increase industrial efficiency, quality and
46、process control; to improve environmental conditions in production processes. LPRs are the preferred measurement tool to achieve the above goals for the following reasons: due to the requirement of having non- contact measurement means because of large level variations, aggressive substances or extr
47、eme temperature/conditions; since other alternative solutions (e.g. ultra- sonic or optical) are too sensitive to contamination or other process conditions; since metallic coating of enclosure structure is not possible (e.g. plastic or glass tanks) because of chemical reactions by aggressive substan
48、ces. ETSI ETSI TR 102 601 V1.1.1 (2007-12) 9 5.2 Market information There is already an established LPR market and certain level measurements cannot be performed by other means than LPR. LPR represent an industrial niche market and should not be considered as a mass market. They cannot be used for c
49、ommunications purposes. An economic benefit results from the introduction of LPR devices in industrial processes. From a marketing point of view, the Level Radar (LR) market consists of both LPR and TLPR. Sales of LPR are low at this moment since certification is a major problem due to lack of both an appropriate harmonized standard and regulation. Therefore, there is an increase of about 20 % of the total European addressable market for level probing radars, if suitable European harmonized conditions for the avail
