EVS-EN 303 364-1-1 V1.1.1:2025

The present document specifies technical characteristics and methods of measurements for ground based monostatic ATC solid state primary surveillance radars that are intended to work with a waveguide-based rotating passive antenna and have the following characteristics:
• operation in the 1 215 MHz to 1 400 MHz frequency range;
• transmitter output peak power up to 100 kW;
• the transceiver output uses an RF circulator;
• a piece of waveguide of at least 66 cm is integral to the transceiver.
NOTE 1: Phased array ATC primary surveillance radars are not covered by the present document.
NOTE 2: 66 cm equals 2 times the cut-off wavelength of a WR650/WG6/R14 waveguide which is typically used in
the 1 215 MHz to 1 400 MHz frequency range.
NOTE 3: The relationship between the present document and essential requirements of article 3.2 of
Directive 2014/53/EU is given in Annex A.
