The invention discloses an aerodynamic capture maneuvering guidance method based on sideslip correction, and relates to the field of orbit braking energy consumption optimization, and the method comprises the steps: building a maneuvering dynamics model of a spacecraft in an atmospheric flight section in an atmospheric capture maneuvering process; s2, performing profile analysis on the maneuvering and dynamical model based on a saturation function, and designing a target aerodynamic capture heeling angle reference trajectory; basic parameters of the saturation function are set through the rolling maneuvering capability of the spacecraft, and guidance parameters with the heeling angle as modulation in the aerodynamic capture process are determined. According to the method, through a saturation function approximation step type heeling angle time sequence profile, the sensitivity of guidance parameters can be remarkably reduced, and the robustness of a guidance system is enhanced.
