Electromagnetic compatibility and Radio spectrum Matters (ERM) - Road Transport and Traffic Telematics (RTTT) - Automotive radar equipment operating in the 24,05 GHz up to 24,25 GHz or 24,50 GHz frequency range - Part 1: Technical characteristics and test methods
The present document specifies the technical requirements and methods of measurement for automotive radar equipment operating in the 24,05 GHz to 24,25 GHz frequency range or in the 24,05 GHz to 24,50 GHz frequency range intended for Narrow Band Short Range Radar (NB SRR) for Road Transport and Traffic Telematics (RTTT) applications such as Automotive Cruise Control (ACC), Collision Warning, Anti-Collision (AC) systems, obstacle detection, Stop and Go, blind spot detection, parking aid, precrash, backup aid and other safety relevant automotive applications. The present document contains the technical characteristics and test methods for narrowband short range radar equipment fitted with integral antennas and applies to transmitters and receivers with integral antennas operating in all or part of the range from 24,05 GHz to 24,50 GHz. The present document covers the basic NB SRR as provided by the EN 302 858-1 (V1.2.1) operating in the frequency range of 24,05 GHz to 24,25 GHz. Additionally, the present document specifies the WLAM (Wideband Low Activity Mode) mode, operating from 24,05 GHz to 24,50 GHz. The operation of this mode is optional and specified in the normative annex B of the present document. The present document does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable. The present document covers only NB SRR equipment for vehicles. The present document complies with field limits for human exposure to electromagnetic fields as provided by the EC Recommendation 1999/519/EC [i.4] and the methods for compliance demonstration in EN 62479:2010 [i.5]. Table 1 shows the frequency bands as designated to narrow band short range radar devices.
Elektromagnetna združljivost in zadeve v zvezi z radijskim spektrom (ERM) - Cestna transportna in prometna telematika (RTTT) - Avtomobilska radarska oprema, ki deluje v frekvenčnem območju od 24,05 GHz do 24,25 GHz ali 24,50 GHz - 1. del: Tehnične karakteristike in preskusne metode
Ta dokument določa tehnične zahteve in merilne metode za avtomobilsko radarsko opremo, ki deluje v frekvenčnem območju od 24,05 GHz do 24,25 GHz ali 24,05 GHZ do 24,50 GHz, ki je namenjen ozkopasovnemu radarju kratkega dosega (NB SRR) za naprave za cestno transportno in prometno telematiko (RTTT), kot so avtomobilski tempomat (ACC), sistem za opozarjanje pred trki, sistem za preprečevanje trkov (AC), zaznavanje ovir, zagotavljanje funkcije »ustavi in spelji«, zaznavanje mrtvih točk, pomoč pri parkiranju, opozarjanje na nesreče, podpora in druge avtomobilske naprave, ki zagotavljajo večjo varnost. Ta dokument vsebuje tehnične karakteristike in preskusne metode za ozkopasovno radarsko opremo kratkega dosega, opremljeno z vgrajenimi antenami, ter se uporablja za oddajnike in sprejemnike z vgrajenimi antenami, ki delujejo v celotnem frekvenčnem območju 24,05 GHz do 24,50 GHz ali le v njegovem delu. Ta dokument obravnava osnovni ozkopasovni radar kratkega dosega, kot je določeno v standardu EN 302 858-1 (V1.2.1), ki deluje v frekvenčnem območju od 24,05 GHz do 24,25 GHz. Poleg tega ta dokument določa širokopasovni način majhne dejavnosti (WLAM), ki deluje v frekvenčnem območju od 24,05 GHz do 24,50 GHz. Delovanje tega načina je neobvezno in opredeljeno v normativnem dodatku B tega dokumenta. Ta dokument ne vključuje nujno vseh karakteristik, ki bi jih lahko potreboval uporabnik, in ne predstavlja nujno najboljšega mogočega delovanja. Zajema le ozkopasovno radarsko opremo kratkega dosega za vozila. Ta dokument je skladen s terenskimi omejitvami izpostavljenosti ljudi elektromagnetnemu sevanju, kot je določeno v priporočilu Sveta 1999/519/ES [i.4], in z metodami za dokazovanje skladnosti iz standarda EN 62479:2010 [i.5]. V preglednici 1 so prikazani frekvenčni pasovi, kot so dodeljeni ozkopasovnim radarskim napravam kratkega dosega.

Intellectual Property Rights
IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://ipr.etsi.org).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.
Foreword
This draft 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
standards EN Approval Procedure.
For non EU countries the present document may be used for regulatory (Type Approval) purposes.
Equipment compliant with the present document is intended for fitment into road vehicles, therefore it is subject to
automotive EMC type approval and needs to comply with Directive 95/54/EC [i.3]. For use on vehicles outside the
scope of Directive 95/54/EC [i.3] compliance with an EMC directive/standard appropriate for that use is required.
The present document is part 1 of a multi-part deliverable covering Electromagnetic compatibility and Radio spectrum
Matters (ERM); Road Transport and Traffic Telematics (RTTT); Automotive radar equipment operating in the
24,05 GHz up to 24,25 GHz or 24,50 GHz frequency range, as identified below:
Part 1: "Technical characteristics and test methods";
Part 2: "Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive".
Proposed national transposition dates
Date of latest announcement of this EN (doa): 3 months after ETSI publication
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 6 months after doa
Date of withdrawal of any conflicting National Standard (dow): 6 months after doa

1 Scope
The present document specifies the technical requirements and methods of measurement for automotive radar
equipment operating in the 24,05 GHz to 24,25 GHz frequency range or in the 24,05 GHz to 24,50 GHz frequency
range intended for Narrow Band Short Range Radar (NB SRR) for Road Transport and Traffic Telematics (RTTT)
applications such as Automotive Cruise Control (ACC), Collision Warning, Anti-Collision (AC) systems, obstacle
detection, Stop and Go, blind spot detection, parking aid, precrash, backup aid and other safety relevant automotive
applications.
The present document contains the technical characteristics and test methods for narrowband short range radar
equipment fitted with integral antennas and applies to transmitters and receivers with integral antennas operating in all
or part of the range from 24,05 GHz to 24,50 GHz.
The present document covers the basic NB SRR as provided by the EN 302 858-1 (V1.2.1) operating in the frequency
range of 24,05 GHz to 24,25 GHz.
Additionally, the present document specifies the WLAM (Wideband Low Activity Mode) mode, operating from
24,05 GHz to 24,50 GHz. The operation of this mode is optional and specified in the normative annex B of the present
document.
The present document does not necessarily include all the characteristics which may be required by a user, nor does it
necessarily represent the optimum performance achievable.
The present document covers only NB SRR equipment for vehicles.
The present document complies with field limits for human exposure to electromagnetic fields as provided by the
EC Recommendation 1999/519/EC [i.4] and the methods for compliance demonstration in EN 62479:2010 [i.5].
Table 1 shows the frequency bands as designated to narrow band short range radar devices.
Table 1: Narrow band short range radar devices frequency of operation
Frequency Bands/frequencies Applications
Transmit and Receive 24,05 GHz to 24,25 GHz Short range radar for vehicle applications
Transmit and Receive 24,05 GHz to 24,50 GHz Short range radar for vehicle applications
(see note)
NOTE: For WLAM operation mode only.
