The invention discloses a satellite-borne integrated SAR (Synthetic Aperture Radar) satellite platform, belongs to the technical field of spacecrafts, and solves the problems that the temperature uniformity of a mounting plate of an existing satellite platform is poor, the appearance envelope of an SAR antenna is large, the high-precision single-machine mounting requirement cannot be met, and the structural strength is low. The platform comprises an SAR antenna, a feed source assembly, a single machine mounting plate, an out-cabin single machine, an in-cabin single machine, a platform main frame and a solar sail. The platform main frame, the single-machine mounting plate and the solar sail form a cabin body; the solar sail is arranged below the platform main frame; an SAR antenna, a feed source assembly and an outboard single machine are mounted on the outer surface of the single machine mounting plate; an in-cabin single machine is mounted on the inner surface of the single machine mounting plate; the single machine mounting plate comprises a honeycomb plate, a metal gasket and a pre-buried heat pipe; the honeycomb plate comprises a honeycomb core and a honeycomb plate skin; and the metal gasket is connected with the embedded heat pipe. The method is suitable for satellite platform, spacecraft platform, spacecraft configuration and layout design, spacecraft structure thermal control design, spacecraft on-orbit monitoring and SAR satellite on-orbit active compensation.
