Abstract：The bistaticradar underlarge-scalespace-air configurationusuallyadopts the working modesof satelite platform transmitandairplatformreception.Inthebistaticcluttersimulationitisimpossibletofollowtheplane-assumptionofthe airbornebistaticradar，andtheearth-spheremodelmustbeconsidered.Thecalculationofthepositionoftheequal-distance cluterringisadficultpointinthecluttersimulation.Onthisbasis，asimulationmetodofiso-rangeringcluttrforbistatic radarinlargescaleisproposed.Consideringthespheremodeloftheearth，thepositioncoordinatesoftheapproximateiso-range ringundertheplaneassumptionarederived.Forasingleclutterpointonthisapproximatelyiso-rangering，theintersetionline of theequidistantelipsoidontheplanefomedbythepointandthetransceiverbaselineiscalculated，andthecurvaturecircle oftheintersectionlineattatpointiscalculated.Afterthesimulationexperiments，thepositionanderroroftheiso-rangering calculatedbythismethodareanalyzed，ndthefectiveness oftheproposedcalculationmethodoftheiso-rangeingisverified. This method can lay a foundation for the research of clutter simulation and clutter suppression algorithm.
