摘　　要：针对多星测控系统提出了一种改进的基于传播算子的虚拟ESPRIT算法，即PMV—ESPRIT算法。此算法结合了传播算子法与虚拟ESPRIT算法的优点，大大提高了计算速度，避免了方位角和俯仰角的配对问题。文章先介绍了此算法的背景，建立了模型讲解算法，最后通过仿真实验来证明其在多星测控系统中的应用。Aimed at the multi-satellite control system, an improved algorithm is proposed, that is two-dimensional virtual ESPRIT algorithm based on propagator method. This algorithm combines the advantages of propagator method and the advantages of virtual ESPRIT algorithm, greatly increases the calculation speed and avoids the matching problems between the azimuth and the elevation an- gles. In this paper, the background of this algorithm is introduced, and the model is established. At last, its application in the multi-satellite control system is demonstrated through simulation.
