Threat assessment method for active proximity spacecraft

The invention discloses a threat assessment method for an active proximity spacecraft, and belongs to the technical field of aerospace. Comprising the following steps: acquiring orbit data of a central spacecraft and orbit data of a non-cooperative target; based on the orbit data of the central spacecraft and the orbit data of the non-cooperative target, extracting threat elements in the approaching process of the non-cooperative target; establishing a solution model of the threat elements, and obtaining a threat element calculation result through the solution model; and establishing a multi-index comprehensive model, inputting the threat element calculation result into the multi-index comprehensive model to obtain a threat index calculation result, and further obtaining a threat evaluation result. Through the constructed evaluation model, the threat degree of the non-cooperative target can be quantitatively calculated only by inputting the initial relative position and speed of the non-cooperative target, an
