Electromagnetic compatibility and Radio spectrum Matters (ERM); Coastal Surveillance@ Vessel Traffic Services and Harbour Radars (CS/VTS/HR); Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive (V1.1.1)
"The present document applies to X-band radar sensors intended for use in Vessel Traffic Services (VTS)@ Coastal Surveillance (CS) or Harbour Radar Systems with the following characteristics: ? Utilizing modulated or unmodulated pulses. ? Transmitter Peak Envelope Power up to 100 kW. ? The transceiver-antenna connection is using a hollow metallic rectangular waveguide. ? The antenna is rotating@ waveguide- based and passive. ? At the transceiver output an RF-circulator is used. NOTE 1: Since transceiver and antenna are hollow metallic rectangular waveguide based@ the frequency range for measurements that needs to be addressed covers 6@56 GHz to 26 GHz. The lower limit of this frequency range is obtained as cut-off frequency of the combination of WR112/R84 taper section and a WR90/R100 Waveguide as defined by IEC 60153-2 [i.2]. The upper limit corresponds to the upper limit stated in ERC/Recommendation 74-01 [i.4]. Other types of waveguide may be used by the same principles to obtain complete measurement coverage of the frequency range of the output flange of the equipment under test. NOTE 2: Since at the transceiver output an RF circulator is used@ it is assumed that the transceiver characteristics remain independent from the antenna. NOTE 3: According to Article 5 of the ITU Radio Regulations [i.5] there are a number of bands between 8@5 GHz and 10 GHz that are allocated to Radiolocation service. There are national deviations to the detailed band usages@ but the basic spectrum usage regulation is the same. The present document is intended to cover the provisions of Directive 1999/5/EC [i.1] (RTTE Directive)@ article 3.2@ which states that ""... radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference"". In addition to the present document@ other ENs that specify technical requirements in respect of essential requirements under other parts of Article 3 of the RTTE Directive [i.1] may apply to equipment within the scope of the present document. NOTE: A list of such ENs is included on the web site http://www.newapproach.org ."
