Resolution 612 (WRC-07) : Use of the radiolocation service between
3 and 50 MHz to support high-frequency oceanographic radar operations
resolves
1. to identify high-frequency oceanographic radar system applications
between 3 and 50 MHz, including bandwidth requirements,
appropriate portions of this band for these applications, and other
characteristics necessary to conduct sharing studies;
2. to conduct sharing analyses between the radiolocation service
applications identified under resolves 1 and incumbent services in the
bands identified to be suitable for the operation of high-frequency
oceanographic radar systems;
3. that, if compatibility with existing services is confirmed under resolves
2, to recommend that WRC-11 consider allocations to the
radiolocation service in several suitable bands between 3 and
50 MHz, as determined in the ITU-R studies, each band not
exceeding 600 kHz, for the operation of oceanographic radars,
Invites ITU-R
1. to complete the necessary studies, as a matter of urgency, taking into
account the present use of the allocated band, with a view to
presenting, at the appropriate time, the technical information likely to
be required as a basis for the work of WRC-11,
