Patent number: 12050085Abstract: Techniques are provided for guiding a projectile. A methodology implementing the techniques according to an embodiment includes generating a roll command based on a roll angle obtained from a steering map that causes a change in range and cross range of the projectile that results in a ground motion closest to a desired ground motion. The method also includes calculating a remaining maximum maneuver distance for the projectile, over a time period extending from the current time of flight to the end of flight. The calculation is based on integration a series of maximum maneuvers, obtained from the steering map, at time intervals within the time period. The method further includes generating a lift command for the projectile based on: distance between the target location and an impact point prediction (IPP) calculated at the current time of flight; an error estimate of the IPP; and the remaining maximum maneuver distance.Type: GrantFiled: December 13, 2022Date of Patent: July 30, 2024Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventor: Paul D.

Patent number: 12044506Abstract: Techniques are provided for off-axis projectile guidance. ? 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.Type: GrantFiled: June 15, 2021Date of Patent: July 23, 2024Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Paul D.

Patent number: 11808868Abstract: A sensor determines the spin rate or rotation frequency of a munition body of a guided projectile relative to precision guidance munition assembly. The spin rate is used to determine launch velocity of the guided projectile early in flight before GPS is operationally active. The launch velocity is used to determine whether a corrective maneuver is needed to change the range of the guided projectile. Logic can control the canards on the canard assembly in response to the determination that a corrective maneuver is needed.Type: GrantFiled: August 30, 2019Date of Patent: November 7, 2023Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Paul D.

Patent number: 11733367Abstract: The system and method for chromatic correlation interferometry direction finding (CIDF) used to resolve ambiguities. Ambiguities are overcome by correlating over a range of frequencies. In some cases, multiple (i.e., 2 or more) frequencies or a continuous range of frequencies are used to make a more robust correlation manifold. As the complex response manifold is frequency dependent, using a set of two or more manifolds provides a significant reduction of false peaks.Type: GrantFiled: April 14, 2021Date of Patent: August 22, 2023Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Paul D.

Patent number: 11435430Abstract: A method for launching a round from an airborne platform, receiving a plurality of RF signals at the round, determining an amount of time between a first and second received RF signal, where the second signal is a multi-path signal and the first signal is a direct path signal.
