Study on principle of single satellite integrated aperture positioning system
Based on synthetic aperture technique,a single satellite DOA location system is proposed,and its accuracy and sensitivity are analyzed.Theoretical analysis and simulation results show that this method can im-prove system sensitivity while maintaining high accuracy,thus effectively reducing the complexity of antenna ar-ray system.It provides an effective solution to the problem that the multi-channel received signals of the single star interferometer are only used for location and can not be synthesized effectively to improve the sensitivity,which leads to the large scale of the system.
