Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio

21、spectrum Matters (ERM). Introduction The radar level gauges covered by the present document do not use the time domain UWB short pulses. Instead the radar level gauges covered by the present document use the frequency domain FMCW and/or SFCW. Thus the emission bandwidth generated by the FMCW and/or

22、SFCW radars is strictly controlled. The specified requirements in the present document describe the worst case scenario (i.e. the highest emissions to the environment) and shall be seen as a feasible test method to prove compliance of radar level gauging applications in still pipes. The background a

23、nd related applications have been described in TR 102 750 i.2 where the applications have been considered indoor like systems.
