英文摘要 | This work presents a novel on-line estimation approach to estimation of the trajectory of a tactical ballistic missile with simple maneuvering in the terminal phase. This proposed approach incorporates the extended Kalman filter and an innovative recursive input estimator into the hypothetical testing scheme. Relatively simple steering is accomplished by the ballistic missile and is considered to be an abrupt lateral acceleration in the dynamic equation. Also formulated herein is a regression equation between the observed value of the residual sequence and the theoretical residual sequence of the extended Kalman filter with no input. In addition, a recursive least-squares estimator is provided not only to extract the magnitude of the input, but also to provide a testing criterion for detecting the onset and presence of the input. Numerical simulation has demonstrated the superior capabilities of this input approach. Moreover, trajectory estimates of the two variations of the ballistic coefficient can verify the robustness and computational stability within very short time. |
