Space non-cooperative target cooperative capture method based on multi-spacecraft formation

The invention provides a space non-cooperative target cooperative capture method based on multi-spacecraft formation. The method is characterized in that firstly, task analysis of a task of cooperatively capturing a non-cooperative target by two spacecrafts is carried out, and a capture dynamics modeling method adopting two spacecraft formations is provided, so a problem of motion cooperation of the two capture spacecrafts is solved, and the two capture spacecrafts cooperatively and synchronously capture the non-cooperative target in a space; secondly, collision is considered, on the basis ofan artificial potential field method, the two spacecraft cooperative capture strategies are provided, collision avoidance between captured spacecrafts and between the spacecrafts and the space non-cooperative target can be achieved through the strategies, and the spacecrafts can bypass solar cell panels, cabins and the like of the target spacecrafts to reach preset positions and finally synchronously reach multiple captur
