Space target guided imaging task planning method based on agile optical remote sensing satellite

Abstract

The invention discloses a space target guided imaging task planning method based on an agile optical remote sensing satellite, belongs to the technical field of space remote sensing imaging, and aims to solve the problems in the prior art. The method comprises the following steps: dividing a planning time period into a plurality of independent windows at intervals of 300s, and calculating a relative motion speed vector and a relative position vector of a remote sensing satellite and a space target in a future task planning time period; resolving to obtain all visible windows; selecting a window with the smallest relative distance between the space target and the remote sensing satellite; calculating the exposure duration t0 required by the shooting task; determining an imaging mode; determining attitude pointing during remote sensing satellite imaging; and finally, outputting a final imaging moment, exposure duration, an imaging mode and attitude pointing of remote sensing satellite imaging. By utilizing the agility of the earth remote sensing satellite, the space target shooting can be simply and efficiently realized through reasonable task planning, so that the earth 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, and in particular relates to a space target guided 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 movement, wide range of motion, uncertain trajectory, and weak target characteristics. How to use optical imaging technology to monitor and measure space targets is of great significance and research value in both military and civilian applications. [0003] At present, most of my country's space target monitoring equipment is based on ground-based photoelectric theodolite. Due to the limited territory, it is difficult for ground-based monitoring methods to form a normalized global domain mon...
