基于RCS数据的矩形体卫星尺寸估计研究
Research on Size Estimation of Rectangular Satellite Based on RCS Data
摘要
Abstract
The traditional satellite size estimation method based on RCS data mainly uses ellipsoid model for equivalence,which is not accurate enough for estimating the size of rectangular satellites.This article mainly studies the size estimation technology of rectangular satellite.Based on the RCS equivalent formula of the rectangular flat plate that constitutes the rectangular satellite,the relationship between the length and width of the rectangular flat plate and the RCS sequence characteristics is studied;By modeling the motion attitude of a rectangular satellite,the calculation of the satellite's in orbit motion attitude angle has been achieved.Based on the above research,a method for estimating the size of rectangular satellite based on RCS data is proposed,which can estimate the length and width of rectangular satel-lite by using RCS data.The experimental results show that this method can effectively improve the accuracy of size esti-mation for rectangular satellites,providing a new method and idea for spatial target feature recognition.关键词
