Chapter17:FalseRadarMitigation
Fa cilities
17.1Whoneedsit
IfyouareusingDFSfrequencybands5.3/5.4GHzETSIand5.4/5.8GHzFCCyoushouldusethis
facility.
17.2DFSandFalseRadarMitigation
17.2.1AboutDFS
UnderDFSfrequencybands,itmustbeensuredthatradiolinksdonotinterferewithcertain
radarsystemsinthe5GHzband.Ifradarisdetected,theradiolinkshouldmove
automaticallytoafrequency thatdoesnotinterferewiththedetectedradar.
17.2.2WhatisFalseRadarMitigation
FalseRadarMitigationcapabilityisanadvancedmethodtoreduceoreliminatefalseradar
detectionandDFStriggering(“Falsepositives”).
Falseradardetectioncanbecausedbyotherradiostransmissionsorexternalinterference
thatcanbeinterpretedastrueradar.
ThisoptionisactiveonlyinDF Sfrequencybands,5.3/5.4GHzFCC(HBSonly)and5.4/5.8GHz
ETSI(HBS&HSU).
Inwhatfollowsfalseradarmeansanysourceofradar‐likesignalswhicharenotrealradar.
FalseRadarMitigationhastwocomponents:
1. Reductionoffalsepositiveradardetectionbyreductionoftheprobabilityofdetectingany
kindoffalseradars,whileallowingthesystemtodetectrealradarsignals.
2. Eliminationofdetectionofspecificfalseradartypesbyblockingdetectionoffalseradars
ofaspecifictype.Therearethreetypesofradars:
•Fixed:Falseradarswithfixedpulsewidthhavingfixedrepetitionfrequency
