Abstract:
1. A method for measuring the motion of an object directed to at least one target using at least one source that generates wave fields in a non-vacuum stochastic system having a plurality of objects, the at least one object generating at least one diffraction field in the path of a propagating wave field created by the source, and at least one object is a projectile or a measurement instrument that can be driven towards the target, the measurement instrument being configured to measure at least one diffraction field quantity, the source, the at least one measurement instrument or the at least one projectile being configured to communicate with each other, and the non-vacuum stochastic system including: (1) a discrete time variable n, (2) a state vector z(n) for each time n, (3) at least one measurement vector zm(n) that includes a set of measurement variables measuring at least one diffraction field quantity, (4) at least one motion noise vector and at least one measurement noise vector being independent and uncorrelated in time, (5) a set of motion equations, (6) a set of measurement equations, and (7) a probability density for an initial state vector z(0) at an initial time, the method comprising:
