The Time-Domain Scattering Characteristics Analysis of the Typical Satellites in Different Space Attitudes

A method to study the time-domain/wide-band scattering characteristics variety with satellite attitude change is proposed in this paper, and the time-domain and wide-band electromagnetic scattering characteristics of typical spin-stabilized and triaxis-stabilized satellites in different space attitude conditions (rolling, pitch and yaw) are investigated by using the proposed methods and the parallel finite-difference time-domain (FDTD) code. The results show the change of rolling attitude more easily arouses the variety of scattering characteristic of satellite target than pitch attitude change does. The calculation results may be helpful to the wide band radar for detecting, identifying and tracking of the satellite targets.
