According to the characteristics of Fast Speed Mirror, the paper discusses that, in a FSM composite axis control system, the mechanism of the servo control, the main system performance, the speed loop of subsystem and effects of automatic zero locking system. Combined with traditional methods, a new structure of axial subsystem is proposed, to improve the rapid high-precision tracking technique. From theory to experimental model, the paper made a detailed analysis.

Unambiguous Tracking

The autocorrelation function of Composite BOC(CBOC) signals has many side-peaks, which leads to the ambiguous problem. To solve this problem, an improved two-stage unambiguous tracking scheme is proposed in this paper. In the first stage, an unambiguous correlation function with narrow main peak is constructed by combining four out of twelve sub-correlation functions. In the second stage, by adding the rest of sub-correlation functions, the final correlation function with sharper and higher main-peak is developed based on the preparatory function from the first step. Numerical results demonstrate that compared to the original methods, the proposed scheme has a better tracking performance and can effectively suppress the short delay multipath.
