These don't follow a simple ballistic path. I believe that the radar takes enough data points to calculate the actual trajectory, based either on a ballistic trajectory, or on a rocket-assisted trajectory. It probably can assume (but I'm guessing here) that the rocket burn is "stable" (i.e. constant over a period of time, or has other known characteristics) when it calculates the trajectory of a non-ballistic "bullet". dave
