Given a trajectory and unit pointing vectors determined based on a planar or other approximation of a shock wave from a projectile, the times that sensor elements(60, 61, 62) should have detected a shock wave based on the conical geometry of the shock wave are calculated. A difference between the calculat ed times and the actual times measured at the sensor elements (60, 61, 62) may be minimized by perturbing the unit vector.. The minimization may be performed by perturbing the unit vectors. When the perturbation of the unit vectors resul ts in an acceptable difference between the calculated times and the actual time s measured, an accurate trajectory of the projectile is generated from the perturbed unit pointing vectors.
