During the debris population derivation in current versions of the orbital debris engineering model, NASA's ORDEM2010 and ESA's MASTER-2009, the ejecta model is simplified in some degree so as to link the populations with data. As a requirement for more accurate space debris environment model, researches on the statistical inference of population derivation of the ejecta model are essential. We simulate single particle impacts in various relative velocity directions in space with current ejecta model, in order to figure out features in ejecta orbital evolution such as orbital lifetime. In view of the nearly continuous generation of this secondary source, information of the on-orbit spacecraft area especially the debris flux is also taken into account. The simulation results show that by assuming the ejecta model is precise, these features which make the ejecta model distinct could increase the debris population accuracy before being linked to the observed data.
