The present document specifies technical characteristics and methods of measurements for monostatic X-band radar

sensors intended for the surveillance of airspace traffic with the following characteristics:

• Operating in the frequency range 8 500 MHz to 10 000 MHz utilizing modulated pulses.

• The transceiver-antenna connection is using a hollow metallic rectangular waveguide.

NOTE 1: Since transceiver and antenna are hollow metallic rectangular waveguide based the frequency range for

measurements that needs to be addressed covers 6,56 GHz to 26 GHz. The lower limit of this frequency

range is obtained as cut-off frequency of the combination of WR112/R84 taper section and a WR90/R100

Waveguide IEC 60153-2 [i.3]. The upper limit corresponds to the upper limit stated in Table 1 of ERC

NOTE 2: Since at the transceiver output an RF circulator is used, it is assumed that the transceiver characteristics

allocated band: frequency span that regionally or nationally is allocated to one or more radio services on a primary or

NOTE: A table of national frequency allocations are normally available from the radio authority for each national

state. Also a generic frequency allocation table is available in the ITU Radio Regulations [3].

declared band: band or bands within which the product under test is declared to operate in the applicable operating

NOTE 2: The declared band for a given region or country is always contained within the allocated band.

idle/standby state: where the transmitter is available for traffic, but is not in the active state

Minimum Detectable Signal (MDS): measure of the lowest detectable signal amplitude for a given signal type for a

NOTE: For solid state radars a processing gain can be associated with a received signal. This processing gain has

the effect of lowering the MDS level in comparison to a MDS which is based only on noise temperature.

MDS in the present document is defined as including the processing gain for the chosen test signal.

necessary bandwidth: width of the frequency band which is just sufficient to ensure the transmission of information at

the rate and with the quality required under specified conditions for a given class of emission

occupied bandwidth: width of a frequency band such that, below the lower and above the upper frequency limits, the

mean powers emitted are each equal to a specified percentage β/2 of the total mean power of a given emission

peak envelope power: average power supplied to the antenna transmission line by a transmitter during one radio

frequency cycle at the crest of the modulation envelope taken under normal operating conditions

The measured -40 dB bandwidth (B ) is the measured bandwidth of the emission 40 dB below the measured PEP.
