Artillery Firing Shift with Two Registration Targets

Firing shift is the shifting of artillery fire from one target (registration) to another by the application of corrections determined from the adjustment of the initial firing data for the first target to the second (application). In this paper, a shift method based on simultaneous firing at two different registration targets rather than a single one is introduced. A method is presented for using the observed data to explicitly solve for four major environmental parameters that affect ballistic trajectories and subsequently update them for the application mission. The distribution of the remaining errors is determined and compared with that of other correcting algorithms. Numerical examples show the potential of the proposed method.
