Interception of ballistic targets

Intercepting an incoming artillery or mortar round is receiving interest as an area-protection mechanism. A problem has been that estimation, based on 6-DOF equations for both the incoming round and the interceptor round or missile, is too time consuming from a computational perspective. This report presents a basic simulation in MATLAB that is used to find the maneuver control and the aimpoint or lead angle needed to intercept an incoming round. The method uses reduced dynamics flight models for the interceptor and the incoming round. Also, questions relating to the probability of a hit given a specific standard deviation and bias are addressed.
