The invention discloses an active simulation wind tunnel test method for a ship wake flow field in a carrier-based aircraft landing process, belongs to the technical field of wind tunnel tests, makes up for the deficiency of the passive simulation capability of the existing ship wake flow field, and solves the problem that the landing speed and the navigation speed of an aircraft carrier cannot be unified in carrier-based aircraft landing characteristic research. A ship wake flow field active simulation device is installed at an inlet of a test section, so that speed turbulent flow is generated at the downstream of the test section, speed measurement is performed by means of a flow field calibration system, a time domain speed model is obtained by using a ship wake flow field mathematical modeling method, and a flat plate swing gain control coefficient is calculated by calibrating a disturbance speed field. According to the test method, the aircraft carrier wake flow field can be simulated in a wind tunnel environment, and the test method has the advantages that the aircraft carrier wake flow velocity field intensity simulation capability is high, the integral scale adjustment range is wide, and the simulation repeatability is good.
