Abstract :
This paper introduces a solution method for ship swaying motion differential equations—maximum likelihood parameter identification method. To evaluate its data processing effects, we have taken the real-time measurement data as a research object and computed with several algorithms, at the same time compared their prediction results. The results show that parameter identification method for differential equation is reliable in calculation, whose accuracy can satisfy the demand for shipboard equipments to accurately track space targets, which is recommended to use for ship swaying measurement data processing.
