Extraterrestrial celestial body soft landing augmented curvature guidance method

The invention discloses an extraterrestrial celestial body soft landing augmented curvature guidance method, and belongs to the technical field of deep space exploration. The implementation method comprises the following steps: establishing a kinetic equation of the detector under a planetary surface fixed connection coordinate system; and according to a track geometric curvature theory, in combination with an energy optimal guidance law, a basic form for constructing track curvature guidance is established, and an expansion form of curvature guidance is obtained through derivation. In the trajectory curvature guidance law, whether a detector is in an obstacle influence area or not and compensation thrust applied to the obstacle influence area are represented through a thrust compensation item, the extraterrestrial celestial body soft landing augmented curvature guidance law is obtained, the compensation thrust only acts on a certain space area near a terrain obstacle, and energy consumption is closer to an e
