Problems solved by technology

But its disadvantage is: as the swing angle increases, the attitude control ability of the whole star and the ground resolution will be significantly reduced.
However, with the popularization and industrialization of space-to-ground remote sensing technology and the development status of remote sensing imaging payloads in orbit and under research at home and abroad, it can be seen that the development trend of remote sensing imaging payloads in the future is light, small, agile, ultra-large and wide , high resolution and high timeliness, but obviously the above three existing imaging technologies cannot fully meet these conditions

Abstract

The invention discloses an ultra-wide-width imaging method based on the whole satellite fast pendulum. The method comprises the steps of: setting control parameters of an agile satellite, swinging a whole satellite to an initial position, wherein the longest time limit of completing once pendulum is tmax, it is set that the satellite starts imaging from an angular velocity of 0, the time of swinging back to the imaging starting position again is 5, and when the control parameters of the agile satellite are set, t<tmax; setting and inputting the control parameters meeting the conditions above when the agile satellite is operated, inputting the control parameters into an attitude swing control component of the agile satellite, controlling the agile satellite to perform fast reciprocating swing by the attitude swing control component, and performing on-the-spot observation by employing an optical camera mounted on the agile satellite to complete a plurality seamless and continuous imagingstripes so as to continuously achieve ultra-wide-width seamless and continuous imaging. The ultra-wide-width imaging method based on the whole satellite fast pendulum effectively achieves the ultra-wide-width seamless and continuous maneuver imaging of a ground target, and is high in maneuverability, high in efficiency and high in resolution.

Description

technical field [0001] The invention relates to the field of space optical remote sensing technology, in particular to an ultra-wide-width imaging method based on the whole star fast swing. Background technique [0002] Space-to-earth remote sensing imaging technology has the characteristics of wide observation range, rich target information, and high timeliness of information. It plays an extremely important role in the fields of target monitoring, geographic surveying and mapping, national defense security, and agricultural and forestry resources census. Ultra-large-width earth observation can significantly shorten the revisit cycle of satellite-to-earth targets and effectively improve the timeliness of detection information, which makes users' demand for ultra-large-width, high-resolution, and high-timeliness imaging data more and more urgent. [0003] In the prior art, the methods for obtaining ultra-large-width, high-resolution, and high-timeliness imaging data mainly i...
