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 [i.2] with a minimum length
between the output of the transmitter and the input of the antenna of 2 886 mm (20 times the wavelength of the
waveguide cut-off frequency).
• 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 polarized or it can be
both simultaneously.
• At the transceiver output an RF circulator is used.
