Based on the analysis of the dynamic characteristics of a continuous thrust spacecraft, the variation of its orbit radius during orbital climb is studied, and the process of orbital climb is described in a formulaic manner, followed by identification of its thrust parameters. Firstly, describe the basic problem of orbital climb, analyze the spatial coordinate system and radar visibility characteristics; Secondly, formula derivation was carried out, and the transformation between spatial coordinate systems and the McLaughlin expansion of orbit radius were carried out; Finally, experimental simulations were designed to verify the accuracy of the proposed thrust parameter identification method. Using the LM algorithm, the solution accuracy can reach 1.5%.
