The invention relates to a spacecraft maneuver detection method, and belongs to the field of spaceflight measurement and control. According to the method, the mechanical energy change and tangential acceleration of the spacecraft are calculated by adopting an energy method, whether the spacecraft has maneuvering is analyzed by calculating the mechanical energy change of the spacecraft, the non-conservative force and the maneuvering acceleration are calculated according to the relation between the orbit mechanical energy and the non-conservative force, whether maneuvering exists is judged, and the maneuvering time and the magnitude of the maneuvering force are determined. Therefore, according to the method, the maneuvering time and the magnitude of the maneuvering force can be solved at a time, the speed is high, and the accuracy is high; in addition, the method does not need to add extra observed quantity, and the requirement for coverage of track data is not high, so that the method is convenient to operate, high in applicability and low in cost.
