A determination of missile impact position coordinates from several plume positions measured by scanning radars is described. The coordinates are calculated according to a weighted least squares criterion where the plume positions are constrained to follow the speed and direction of the wind. Corrections for 1 target dependent effects caused by plume expansion after impact and 2 a down range shift from impact of the initial plume position Due to kinetic energies of impact are incorporated in the determination of impact position coordinates. Covariances, variances, error ellipses, residuals, and downcross range uncertainties are also calculated with the mathematics provided. Results obtained from applications of this technique to data from Operations 8633, 4103, and 6667 are presented both numerically and graphically. Summary remarks concerning accuracy of the results are included in the report. Author
