Xi'an, Shaanxi, 710072, China. Abstract- Fortheapplication ofairborne target drone, a distance measuring algorithm basedonframesynchronizing codeispresented. Taking thewireless datalinkofaairborne target droneforexample, this paperelaborates themethodthat takes thesynchronizing codeofthedatalinkframeinwireless telecontrol(TC) andtelemetering (TM)asthemeasuring code, andgives outtheprinciple ofthemeasurement, thedesign ofthe circuit andtheanalysis oftheerror. Regarding theground control station asthezerodistance benchmark, comparing the radaridentified flight dataandtheairborne target drone measured data, these twoarewellfitting inplot. Besides, the meansquareerrorofthedistance thatairborne target drone measured isinrangeof20m,whichmeetsthedemanded error in rangeof30m.Manytypesofairborne target drones andmany flight experimentations showthatthismethodissimple, good-precision, lowchannel energy spentandlowsystem cost. Thismethodcanalsobeapplied tootherwireless system that needsmeasuring continuously inrangeof300Km.
