The present document specifies technical characteristics and methods of measurements for S-band meteorological radar systems intended for the surveillance and classification of hydrometeors with the following characteristics: • Operating in the following frequency range: - 2 700 MHz to 2 900 MHz. • Utilizing unmodulated pulses or phase/frequency modulated pulses also known as pulse compression. • The maximum output power (PEP) does not exceed 1 MW (i.e. 90 dBm). • The transceiver antenna connection and its feeding RF line use a hollow metallic rectangular waveguide. • The antenna rotates and can be changed in elevation. • The used waveguide is WR284/WG10 waveguide according to IEC 60153-2. • The antenna feed is waveguide based and the antenna is passive. • The orientation of the transmitted field from the antenna can be vertical or horizontal orientated or it can be both simultaneously. • At the transceiver output an RF circulator is used. NOTE 1: Since at the transceiver output an RF circulator is used, it is assumed that the transceiver characteristics remain independent from the antenna. NOTE 2: According to provision 5.423 of the ITU Radio Regulations, ground-based radars used for meteorological purposes in the band 2 700 MHz to 2 900 MHz are authorized to operate on a basis of equality with stations of the aeronautical radio navigation service. NOTE 3: Further technical and operational characteristics of meteorological radar systems can be found in Recommendation ITU-R M.1849-1. NOTE 4: The relationship between the present document and essential requirements of article 3.2 of Directive 2014/53/EU is given in Annex A.
