NLT 045 NMT 080 b) boundary between OOB and spurious emissions (D.6.e); c) spur
28、ious emissions SM.329 (D.6.c). Spurious emission limits for radar systems have been incorporated into section II of appendix 3 of the Radio Regulations, in terms of level, but not in terms of frequency range. There is no intention at present of a similar treatment for either the OOB or adjacent allo
29、cated band limits. It has been agreed that within the ITU WRC 2003 Agenda item 1.8.1, the boundary between OOB and spurious emissions will be defined for all radio services and incorporated into Appendix 3 of the Radio Regulations. As this will not occur until after the date of 1 January 2003 (the d
30、ate at which the new spurious limits apply for new radar installations), there is a need for this standard to define the boundary conditions based upon the text contained in the ITU-R Recommendation SM.1539 (D.6.e). The purpose of this annex is to define how the requirements of Appendix 3 of the Rad
31、io Regulations and these new ITU Recommendations concerned with unwanted emissions are to be implemented with regard to marine radars. This includes the requirements, method of measurement, the results to be obtained and the interpretation of the measurement results. D.2 Requirements The requirement
32、s are defined in Appendix 3 of the Radio Regulations and the recommendations listed above in D.1. The boundary between the OOB and spurious domains and the OOB mask are defined in the OOB recommendation Annex 8 in the following manner a) (Boundary and mask) “the mask rolls off at 20 dB per decade fr
33、om the 40 dB bandwidth to the spurious level specified in Appendix 3 of the Radio Regulations. The B40 dB bandwidth can be offset from the frequency of maximum emission level, but the necessary bandwidth (1.152 of the Radio Regulations) should be contained completely within the allocated band”. b) (
34、Exclusions) “the OOB limits are not applicable inside exclusive Radiodetermination and or Earth Exploration Satellite (EES) and Space research service bands, but do apply at the band edges.” These requirements are illustrated in Figures D.1 and D.2. The OOB masks shown in Figures D.1 and D.2 are cal
35、culated using the transmitted pulse width and rise time. Page 57 EN 609361:2000 3002 yluJ 7 BSI 7 July 2003 Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 13 13:25:05 GMT+00:00 2006, Uncontrolled Copy, (c) BSI The necessary bandwidth and the 40 dB bandwidth are generally centred about the opera
36、ting frequency but may be offset to take account of spectrum asymmetry. The OOB mask commences at a level of 40 dB and falls off at the rate of 20 dB per decade until it meets the spurious emission limit at the OOB boundary. When the calculated 40 dB bandwidth falls within the allocated band the OOB
37、 mask commences at the edge of the allocated band. When the 40 dB bandwidth falls outside the allocated band the OOB mask commences at that point in the adjacent band. The OOB mask can be offset further into the adjacent band to allow for spectrum asymmetries, but the necessary bandwidth associated
38、with this mask shall be contained completely within the allocated band. The OOB mask emission limits only apply outside the adjacent bands, i.e. below 2,7 GHz and above 3,3 GHz in the case of radars operating in the 2,9 GHz to 3,1 GHz band, and below 8,5 GHz and above 9,8 GHz in the case of radars o
39、perating in the 9,3 GHz to 9,5 GHz band. Emissions in the spurious domain (Figures D.1 and D.2) shall be at least 43 + 10 log PEP or 60 dB, whichever is the least stringent, below the carrier power, as measured in the far field of the radar. For most current marine radars the limit will be 60 dB and
40、 this means that the spurious domain starts at 5 B40 from the operating frequency of the radar. D.3 Methods of measurement The basic methods of measurement for unwanted emissions are contained in ITU-R Recommendation M.1177 (D.6.a). This describes two methods, referred to as the “direct” and “indire
41、ct” methods. Either method is admissible. Measurements are to be made for all frequencies in the measurement frequency bands specified in the table D.1 below.

42、z0,7 of the waveguide cut-off26 GHz D.4 Guidelines for the use and interpretation of ITU-R Recommendation M.1177 The recommendation provides some specific techniques for the measurement of the unwanted emissions of radar systems, that in principle can be used for any type of radar system. In practic
43、e, the recommendation makes no attempt to provide detailed test methods for each type of system. This standard provides the additional detail required for the minimum test requirements for the measurement of marine radars as a basis for certification, that the particular marine radar system under te
44、st, meets the requirements of the Radio Regulations and ITU-R Recommendations as appropriate.

45、endation on OOB (D.6.d) applies to complex and simple radars with user-selectable pulse waveforms. For a particular radar, the pulse length and rise time for a number of representative pulses (including the shortest and longest pulses) shall be measured and the corresponding B40 bandwidths calculate
46、d. The widest calculated B40 bandwidth shall then be used to create the OOB mask to be applied to that radar. Emission measurements only need to be carried out for the pulse length setting producing the widest calculated B40 bandwidth. D.4.2 Measurement in azimuth and elevation antennas For marine r
47、adars that are essentially surface search radars, there is no requirement to make measurements in the vertical plane. For measurements in the azimuth plane, the antenna may be either rotating or the measurement system may be aligned to the antenna bore sight and measurements in azimuth taken at appr
48、opriate antenna angles where the directions of unwanted emissions are known. Both techniques are admissible and the particular choice shall be made by agreement between the manufacturer and the test authority. In both cases the maximum value of the emission occurring in the azimuth plane shall be re
49、corded over the frequency range defined in table D.1. Provided that all of the antennas to be used with the equipment under test are of the same type, then only the smallest (i.e. that with the largest azimuth beamwidth) need to be used to verify compliance with the unwanted emission requirements.
