摘要
Abstract
The complex conical field of view represents the most complex type among existing sat-ellite payload observation geometrics.A rapid computation method is proposed in this paper for determining the visibility windows of regional targets under complex conical fields of view.By u-tilizing relevant vector geometric relationships and integrating a boundary point identification method for the projected field-of-view region,an analytical approach for visibility determination under discrete temporal steps is developed.Subsequently,based on this framework,accurate re-gional target visibility windows are efficiently obtained through bisection method and Lagrange interpolation of satellite orbit data.Application cases demonstrate that the proposed method achieves a computation time of only 242ms for a 24-hour scenario,yielding an efficiency improve-ment of three orders of magnitude compared to conventional propagation algorithms.Comparison with commercial software results reveals an absolute error of less than 0.3 seconds and a relative error of less than 0.1%,thereby meeting engineering requirements.关键词
