Estimation of vector miss distance for complex objects based on scattering center model

摘要

＜正＞Dear editor,This study presents a method to estimate vector miss distance （VMD） for complex objects based on scattering center （SC） models. In the method, the dependence of the SCs on the aspect angle of the light of sight （LOS） is applied in VMD estimation. This method requires only the radar echoes in a short time frame when the flying object approaches to the closet point of approach （CPA）.
