Electromagnetic compatibility and Radio spectrum Matters (ERM); Short Range Devices (SRD); Equipment for Detection and Movement; Tank Level Probing Radar (TLPR) operating in the frequency bands 5@8@ 10@ 25@ 61 and 77 GHz; Part 1: Technical characteristics
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: ? 4@5 GHz to 7 GHz; ? 8@5 GHz to 11@5 GHz; ? 24@05 GHz to 27 GHz; ? 57 GHz to 64 GHz; ? 75 GHz to 85 GHz. 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. The present document contains the technical characteristics and test methods for TLPR applications and references CEPT/ERC Recommendation for SRDs@ CEPT/ERC Recommendation 70-03 [1].
