Space target guided imaging mission planning method based on agile optical remote sensing satellites

Abstract

A space target guidance imaging task planning method based on agile optical remote sensing satellites belongs to the field of space remote sensing imaging technology, and aims to solve the problems existing in the prior art. The invention divides the planning period into multiple independent windows with 300s duration as the interval, calculates the relative motion velocity vector and relative position vector of the remote sensing satellite and the space target in the future mission planning period; solves to obtain all visible windows; and selects the space The window with the smallest relative distance between the target and the remote sensing satellite; calculate the exposure time t required for the shooting task 0 ; Determine the imaging mode; determine the attitude and orientation of the remote sensing satellite imaging; finally output the final imaging time, exposure time, imaging mode and attitude orientation of the remote sensing satellite imaging. The invention utilizes the agile characteristics of the ground remote sensing satellite, and through reasonable task planning, can simply and efficiently achieve space target shooting, so that the ground remote sensing satellite also has the space-based monitoring capability.

Description

technical field [0001] The invention belongs to the technical field of space remote sensing imaging, in particular to a space target guidance imaging task planning method based on agile optical remote sensing satellites. Background technique [0002] With the development of space technology and the increasing dependence of the economy and society on space resources, the number of man-made space targets is increasing year by year. Space targets have the characteristics of fast moving speed, wide moving range, uncertain trajectory, and weak target characteristics. How to use optical imaging technology to realize the monitoring and measurement of space targets has important significance and research value in both military and civil aspects. [0003] At present, most of my country's space target monitoring equipment is mainly based on ground-based photoelectric theodolites. Limited by the territorial scope, it is difficult for ground-based monitoring methods to form a normalize...
