摘要:
Techniques are provided for off-axis projectile guidance. λ methodology implementing the techniques according to an embodiment includes determining a maximum acceleration capability of the projectile based on flight data, control surface positions, and aerodynamic coefficients. The method also includes estimating a range from the projectile to a target. The method further includes calculating a first flight path to provide an offset radar viewing angle to the target that is offset from a longitudinal axis of the projectile and calculating a second flight path to provide for interception of the target by the projectile. The calculations are based on the maximum acceleration capability and the range from the projectile to the target. The method further includes guiding the projectile on the first flight path for an initial period of time and then guiding the projectile on the second flight path until target interception.
