A general theory of recursive estimation is applied to the particular problem of estimating the time history of a re-entry vehicles position, velocity and ballistic coefficient from radar measurements of range, elevation, azimuth and range rate. The resulting algorithms have the following properties 1 Conceptually simple and easy to implement on either general purpose or special purpose computers 2 Noniterative 3 Storage requirements independent of amount of data 4 Extremely fast capable of real time operation and 5 A finite memory span that is, can act like a sliding arc algorithm. Explicit formulae are provided along with general discussions on the basic concept.
