| Summary: | This study proposes the concept of an electronic–mechanical dual stable platform for radars with a three-axis stable turntable. Based on an assumption, an electron stable equation of the first order is applied to the beam pointing correction of the radar with three-axis stable turntable based on the equivalence principle. Furthermore, through a comparative analysis of two kinds of algorithms, it is shown that when the instantaneous value of the tracking error in the platform servo-loop of the mechanical platform is smaller than a certain range, assuming the conditions are established, the error method of the electron stable equation of the first order can directly replace the electron stable equation of the second order that is applied to the spatial orientation correction of the radar beam to improve computational efficiency. At the same time, error analysis was performed on the data link of the dual stable platform.
