5Modulation / Occupied bandwidthPuls, PSK / max. 50 MHz at -40 dBc.
Any emission from the radar antenna in any direction above 10.15 GHz shall be less than -22 dBm e.i.r.p.p..
e.i.r.p.p. is the max. allowed e.i.r. peak power level measured with 10 MHz resolution bandwidth.		Pulsed radars only.
Bandwidth according to ITU-R SM.1541 Annex 8.
