The invention discloses an antenna self-adaptive unwinding method with a limited orientation rotation range on a moving carrier, and belongs to the technical field of satellite communication antennas.According to the method, a multi-turn absolute coded disc is adopted to perform axis angle acquisition, and an angle software partitioning method is adopted to realize azimuth angle partitioning in asoftware mode; two target deck angles AP and AN are obtained through conversion calculation from a target geographic angle to a target deck angle; an optimal initial capture position AP or AN is selected according to the planned heading, thus guaranteeing that the antenna tracking locking time is the longest; and finally, according to an orientation current angle and heading change, a shortest orientation movement distance is planned according to an orientation unwinding processing mechanism, and tracking locking is restored in the shortest time. The method has the characteristics of short time, high precision, high r
