A method is disclosed for ascertaining the motion of at least one target object (A, B, B1, B2). The method comprises a mathematical method of estimation with the aid of a filter solution for estimating and predicting the position and/or orientation of the target object. The filter solution utilises a semi-martingale algorithm. The method is particularly suited for predicting the motion of a highly moveable target such as a ballistic missile B so that it may be intercepted by an interceptor missile C. The motion of the ballistic missile B can be predicted via a semi-martingale process such that abrupt changes in flight motion of the target can be reliably predicted. |
