Abstract:
1. A method for tracking the path of motion of a moving object having a position, speed vector, ballistic coefficient or other state variable that defines a current property of the motion of the moving object, comprising: a) providing data of at least one state variable to be determined, which influences the movement of the moving object, at a first point in time; b) initializing the probability density (p) of the at least one state variable to be determined at the first point in time; c) predicting the probability density (p) of the at least one state variable to be determined at a next point in time after the first point in time; d) verifying whether measurement data are available for calculation of the probability density (p) of the at least one state variable to be determined; d′) recalculating the probability density (p) with these measurement data when such data is available; e) calculating the prediction values of the state variable(s) to be determined from the probability density (p); f) outputting the calculated prediction values to a downstream data processing device to determine at least one future location based on the calculated prediction values; and g) repeating the steps c) through f), wherein the: are performed by discretizing the probability density (p) on sparse grids.
