Foreword
This draft Harmonised European Standard (EN) has been produced by {ETSI Technical Committee Electromagnetic
compatibility and Radio spectrum Matters (ERM), and is now submitted for the combined Public Enquiry and Vote
phase of the ETSI Standardisation Request deliverable Approval Procedure (SRdAP).
The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.2] to
provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation
of the laws of the Member States relating to the making available on the market of radio equipment and repealing
Directive 1999/5/EC [i.1].
Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with
the normative clauses of the present document given in Table A.1 confers, within the limits of the scope of the present
document, a presumption of conformity with the corresponding essential requirements of that Directive and associated
EFTA regulations.
The present document is part 2 of a multi-part deliverable covering Short Range Devices (SRD) using Ultra Wide Band
technology (UWB); Harmonised standard for access to radio spectrum, as identified below:
Part 1: "Level Probing Radar (LPR) equipment operating in the frequency ranges 6 GHz to 8,5 GHz, 24,05 GHz
to 26,5 GHz, 57 GHz to 64 GHz, 75 GHz to 85 GHz for strictly vertical downward installation";
Part 2: "Level Probing Radar (LPR) equipment operating in the frequency range 75 GHz to 85 GHz for

Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and

Introduction
ETSI ERM TGUWB decided to develop more specific standards; this means instead of one generic ETSI EN 302 729
for all Level Probing Radar (LPR) devices, this multi-part deliverable was initiated in order to reflect the intended use
in relation to different aspects of the corresponding regulation ECC Decision (11)02 [i.3].
Part 1 covers the original provisions made in ECC Decision (11)02 [i.3] of 11 March 2011 for LPR equipment with
strictly vertical downward installation (see ECC Decision (11)02 [i.3], first four lines of Table 1 for strictly vertical
antenna orientation).
Part 2 covers the amendments made in ECC Decision (11)02 [i.3] on 5 July 2019 for LPR equipment with tilted
downward installation (see ECC Decision (11)02 [i.3], last three lines of Table 1 for tilted antenna orientation).
Due to the amendment of ECC Decision (11)02 [i.3] on 5 July 2019, ETSI ERM TGUWB decided to follow henceforth
a two-part structure and to only reflect the amendments made in 2019 in part 2 of the series.
More information on the conducted changes in previous versions of the present document can be found in the change
history in Annex H.

1 Scope
The present document specifies technical requirements, limits and test methods for Tilted Level Probing Radar (LPR)
equipment using a downward tilted orientation of the LPR antenna in the three tilting ranges ±15°, ±30° and ±45° in
relation to the strictly vertical downward direction and operating in the frequency range 75 GHz to 85 GHz in outdoor
as well as indoor environments.
Tilted LPR equipment in the scope of the present document consist of a combined transmitter and receiver and are
equipped with an integral or dedicated antenna provided also by the equipment manufacturer. Equipment intended to be
equipped with antennas from a third-party are not covered by the scope of the present document.
Equipment exhibiting a receive only mode or a standby mode are also not covered by the scope of the present
document. Furthermore, the present document is limited to tilted LPR equipment with FMCW modulation.
Tilted LPR equipment and the related categorization is further specified in clause 4.2.
NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.1] is given in Annex A.

4.2 Equipment categories
4.2.1 General
Technical and regulatory requirements for Tilted LPR equipment are provided in general in European
Commission Implementing Decision (EU) 2025/105 [i.7] and ECC Decision (11)02 [i.3], which are based on ECC
Report 139 [i.4]. The present document covers only the essential technical requirements set out in the last three rows in
Table 1 of ECC Decision (11)02 [i.3] for LPR equipment using a tilted vertical downward orientation of the equipment
antenna.
In addition, the manufacturer needs to consider further installation requirements as specified in Annex E and will have
to provide this information to the user/installer. These installation requirements, however, are not subject to Annex A of
the present document.
The following criteria were considered for equipment categorization of the tilted LPR equipment covered by the present
