- Abstract
Space debris is also called orbit debris, which refers to all manmade objects in outer space, except aerocrafts in normal use. With more human activities into outer space, space debris are threatening normal work directly. Researches based on testing or mathematical modeling of space debris have been developed to find their electromagnetic scattering properties. In current research of target characteristics, more attentions are on electrically large objects in optical region, while few papers are published dealing with small space debris in resonant region of the detecting radar. In this paper, dangerous space debris whose characteristic dimensions are comparable to the operating wavelength of the detecting radar are investigated. Their physical lengths are between 1mm and 10cm which correspond to the resonant region in the spectrum. Method of moment (MOM) is applied to evaluate several space debris in resonance and under different polarizations for their scattering properties. Calculated results are compared to measured data and agreement is obtained. The results may provide reference for researchers in this area.
