| Abstract: | The theory of UKF based on unscented transformation is applied to underwater target motion analysis. Specific steps are given, and target motion analysis is discussed. With the measurement of bearings, equations of state and measurement are established. The Monte-Carlo simulation experiment results demonstrate that,in the problem of nonlinear system, UKF has a better performance in precision, and the calculation amount of UKF is smaller,which make it more feasible to use. |
