Attitude Estimation of Parabolic Antenna Based on Imaging Characteristics in Terahertz Band
摘要
The attitude estimation of parabolic antennas plays an important role in the field of space situational awareness. In this paper, imaging characteristic analysis is carried out from the aspects of azimuth and pitch angle, so as to study the variation rules of the RCS, the position, intensity, and distribution of scattering points. Based on the imaging characteristics, the relationship between imaging geometry and attitude inversion can be built, which help us achieve fast attitude estimation.
