The invention provides a single-satellite or multi-satellite heavy orbit interference orbit control method based on an effective vertical baseline, and belongs to the technical field of satellite-borne SAR heavy orbit interference. According to the single-satellite or multi-satellite heavy-orbit interference orbit control method, a reference-observation virtual formation model of heavy-orbit interference is established based on an eccentricity rate vector and a relative inclination angle; based on the geometrical relationship between the latitude of the target detection area and the sub-satellite point latitude and the orbital element, obtaining the relationship between the latitude of the target detection area and the effective vertical base line, and determining the virtual formation effective vertical base line of the reference-observation satellite; and taking the effective vertical base line as an evaluation index to obtain an in-plane/out-of-plane orbit control strategy suitable for single-satellite and multi-satellite heavy-orbit interference. The method solves the problem that at present, domestic and overseas are relatively lack of orbit control strategy research of single-satellite heavy-orbit interference, can provide a new method and a new direction for establishing a remote sensing system in China, can also be applied to air-based situation awareness, and provides support for perfecting an air-based attack and defense system in China.
