Ballistic Wind Correction to Improve Artillery Accuracy

Abstract

A computer-implemented method is provided for implementing wind correction for a projectile launching gun aiming at a target on a gun fire control system on an aircraft. The fire control method includes obtaining first physical parameters; executing a ballistics model to obtain a flight path of the projectile; obtaining number of points for wind direction and velocity across altitudes; executing a tracker model to obtain tracker location and initial gun state; obtaining closure tolerance and cross-correlation factor; modeling wind prediction to obtain a predicted wind column; incorporating the predicted wind column for wind column prediction for a projectile effect; and applying the projectile effect to the fire-control processor to adjust aiming the gun. The first physical parameters include wind column, gun state, ammunition type and aircraft flight conditions. The ballistics model obtains a flight path of the projectile based on the first physical parameters. The tracker model is based on the number of points and the flight path. The wind prediction is based on the closure tolerance, the cross-correlation factor, the tracker location and the initial gun state. The wind direction and velocity are obtained from multiple measurements or alternatively from a single-point measurement.
