Abstract
A method of determining tumbling characteristics of resident space objects includes acquiring a geometry of a target object, generating a distribution of radio scatterers within the geometry of the target, calculating multiple radar cross sections at different angles for the distribution, finding an autocorrelation for each radar cross section versus each angle, using the autocorrelations to find a decorrelation angle, extracting a decorrelation time from radar data of the object, and finding a rotation rate of the object as the tumbling characteristic.
