1Radiocommunication serviceRadiolocation-
2ApplicationRadiolocation (civil)Radar to detect bird migrations with vertical directed antenna.
3Frequency band9300 - 9500 MHzCenter frequency: 9410 MHz, (max. tolerance +/-30 MHz).
4Channelling--
5Modulation / Occupied bandwidth20M0P0N, Pulse lengths: greater or equal than 50 ns (similar to table 7 ITU-R M.1796), Pulse repetition frequencies: max. 3300 Hz /
The -40 dBc bandwidth occupied by the emissions shall be within the 9300 - 9500 MHz band.
Any emission in the main beam direction of the antenna above 10.0 GHz shall be less than:
10 dBm e.i.r.p.p with an antenna gain of 20 dBi,
7 dBm e.i.r.p.p. with an antenna gain of 17 dBi.
e.i.r.p.p. is the max. allowed e.i.r. peak power level measured with 10 MHz resolution bandwidth.
Bandwidth according to ITU-R SM.1541 Annex 8.
Measurement techniques according ITU-R M.1177 shall be used for the determination of the -40 dBc bandwidth.
