Elektromagnetna združljivost in zadeve v zvezi z radijskim spektrom (ERM) - Naprave kratkega dosega (SRD) - Oprema za odkrivanje in premikanje - Radar za sondiranje nivoja v rezervoarjih (TLPR), ki deluje v frekvenčnih pasovih 5,8 GHz, 10 GHz, 25 GHz, 61 GHz in 77 GHz - 1. del: Tehnične karakteristike in preskusne metode
Ta dokument določa zahteve za uporabe radarja za sondiranje nivoja v rezervoarjih (TLPR), temelječih na pulznem RF, FMCW ali podobnih širokopasovnih tehnikah, ki delujejo v naslednjih frekvenčnih pasovih ali delih, kot je opredeljeno v preglednici 1.
Preglednica 1: Frekvenčni pasovi, določeni za radarje za sondiranje nivoja v rezervoarjih (TLPR)
Frekvenčni pasovi/ Frekvence (GHz)
Oddajanje in prejemanje Od 4,5 do 7
Oddajanje in prejemanje Od 8,5 do 10,6
Oddajanje in prejemanje Od 24,05 do 26,5
Oddajanje in prejemanje Od 57 do 64
Oddajanje in prejemanje Od 75 do 85
Preglednica 1 prikazuje seznam frekvenčnih pasov, kot je določen za radarje za sondiranje nivoja v rezervoarjih z Odločbo Komisije 2009/381 [i.4] in priporočili CEPT/ERC/REC 70-03 [i.1], znanimi na datumu objave tega dokumenta. TLPR so uporabljeni za uporabe merjenja nivoja v rezervoarjih. Obseg je omejen na TLPR, ki delujejo kot naprave kratkega dosega, vgrajene v zaprte kovinske rezervoarje ali utrjene betonske ali podobne zaprte strukture, izdelane iz primerljivih oslabljenih materialov, ki zadržujejo snovi, tekočine ali prah.
Uporabe radarja v tem dokumentu niso predvidene za potrebe komunikacij. Njihova predvidena uporaba izvzema kakršno koli namerno uporabo za sevanje v okolje.
Ta dokument velja za TLPR, ki sevajo signale RF neposredno z vrha rezervoarja navzdol na površino snovi, zajete v zaprtem rezervoarju. Kakršno koli sevanje zunaj rezervoarja je posledica puščanja in se šteje za nenamerne emisije. Velja samo za TLPR, nameščene z namenskimi antenami. Ta dokument ne vključuje nujno vseh značilnosti, ki so lahko potrebne za uporabnika, niti ne predstavlja nujno največje dosegljive zmogljivosti.

SIST EN 302 372-1 V1.2.1:2011
ETSI ETSI EN 302 372-1 V1.2.1 (2011-02) 7 1 Scope The present document specifies the requirements for Tank Level Probing Radar (TLPR) applications based on pulse RF, FMCW, or similar wideband techniques, operating in the following frequency bands or part hereof as specified in table 1. Table 1: Frequency bands designated to Tank Level Probing Radars (TLPR)
Frequency Bands/frequencies (GHz) Transmit and Receive 4,5 to 7 Transmit and Receive 8,5 to 10,6 Transmit and Receive 24,05 to 26,5
Transmit and Receive 57 to 64 Transmit and Receive 75 to 85
Table 1 shows a list of the frequency bands as designated to Tank Level Probing Radars in the
EC-Decision 2009/381 [i.4] and Recommendation CEPT/ERC/REC 70-03 [i.1] as known at the date of publication of the present document. TLPRs are used for tank level measurement applications. The scope is limited to TLPRs operating as Short Range Devices, in which the devices are installed in closed metallic tanks or reinforced concrete tanks, or similar enclosure structures made of comparable attenuating material, holding a substance, liquid or powder. The radar applications in the present document are not intended for communications purposes. Their intended usage excludes any intended radiation into free space. The present document applies to TLPRs radiating RF signals directly from the tank top downwards to the surface of a substance contained in a closed tank. Any radiation outside of the tank is caused by leakage and is considered as unintentional emission. It applies only to TLPRs fitted with dedicated antennas. 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. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies. Referenced documents which are not found to be publicly available in the expected location might be found at http://docbox.etsi.org/Reference.

1 Scope
The present document specifies the requirements for Tank Level Probing Radar (TLPR) applications based on pulse RF,
FMCW, or similar wideband techniques, operating in the following frequency bands or part hereof as specified in
table 1.
Table 1: Frequency bands designated to Tank Level Probing Radars (TLPR)
Frequency Bands/frequencies
(GHz)
Transmit and Receive 4,5 to 7
Transmit and Receive 8,5 to 10,6
Transmit and Receive 24,05 to 26,5
Transmit and Receive 57 to 64
Transmit and Receive 75 to 85
Table 1 shows a list of the frequency bands as designated to Tank Level Probing Radars in the
EC-Decision 2009/381 [i.4] and Recommendation CEPT/ERC/REC 70-03 [i.1] as known at the date of publication of
the present document. TLPRs are used for tank level measurement applications.
The scope is limited to TLPRs operating as Short Range Devices, in which the devices are installed in closed metallic
tanks or reinforced concrete tanks, or similar enclosure structures made of comparable attenuating material, holding a
substance, liquid or powder.
The radar applications in the present document are not intended for communications purposes. Their intended usage
excludes any intended radiation into free space.
The present document applies to TLPRs radiating RF signals directly from the tank top downwards to the surface of a
substance contained in a closed tank. Any radiation outside of the tank is caused by leakage and is considered as
unintentional emission. It applies only to TLPRs fitted with dedicated antennas. 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.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
dedicated antenna: antenna that is designed as an indispensable part of the equipment
Device Under Test (DUT): TLPR under test without a test tank
DU: Activity Factor which is used to describe different modulation parameters and activity levels of TLPR devices and
defined as the ratio of active measurement periods (bursts, sweeps, scans) within the overall repetitive measurement
cycle, i.e. T /T
meas meas_cycle
duty cycle: ratio of the total on time of the transmitter to the total time in any one-hour period reflecting normal
operational mode
emissions: signals that leaked or are scattered into the air within the frequency range (that includes harmonics) which
depend on equipment's frequency band of operation
NOTE: For TLPRs there is no intended emission outside the tank.
Equipment Under Test (EUT): TLPR under test mounted on a test tank
equivalent isotropically radiated power (e.i.r.p.): total power transmitted, assuming an isotropic radiator
NOTE: e.i.r.p. is conventionally the product of "power into the antenna" and "antenna gain". e.i.r.p. is used for
both peak and average power.
Frequency Modulated Continuous Wave (FMCW) radar: radar where the transmitter power is fairly constant but
possibly zero during periods giving a big duty cycle (such as 0,1 to 1)

NOTE: The frequency is modulated in some way giving a very wideband spectrum with a power versus time
variation which is clearly not pulsed.
integral antenna: permanent fixed antenna, which may be built-in, designed as an indispensable part of the equipment
operating frequency (operating centre frequency): nominal frequency at which equipment is operated
pulsed radar (or here simply "pulsed TLPR"): radar where the transmitter signal has a microwave power consisting
of short RF pulses
power spectral density (psd): amount of the total power inside the measuring receiver bandwidth
expressed in dBm/MHz
Pulse Repetition Frequency (PRF): inverse of the Pulse Repetition Interval, averaged over a sufficiently long time to
cover all PRF variations
