Publication number: 20240039563Abstract: Techniques to dynamically adjust the corner frequency of a high-pass filter in response to a time-domain amplitude value of an output signal, thereby preserving accuracy while promptly recovering the signal's baseline value. A system can be configured to filter frequency-domain values of an input signal based on a filtering characteristic. The filtering characteristic can be set dynamically in response to a time-domain value of an amplitude of an output signal. The filtering characteristic can comprise a corner frequency, and the system can include a high-pass filter configured to filter out frequency components at frequencies lower than the corner frequency. The system is configured to dynamically change the corner frequency from a first value to a second value, in response to the time-domain value of the amplitude crossing a threshold value. The system may dynamically change the corner frequency within a time interval after the crossing.Type: ApplicationFiled: July 26, 2022Publication date: February 1, 2024Applicant: BAE Systems Information and Electronic Systems Integration Inc.Inventors: James H.

Patent number: 11815335Abstract: Systems are disclosed for navigating a missile to a target using a fixed sensor onboard the missile. In an embodiment, a system includes a launch platform traveling a pre-programmed route to deliver the missile within an area. The missile travels a first flight path through the area in effort to detect targets. If no targets are detected along the first flight path, the missile transitions to a second flight path, different from the first flight path, to locate targets off-axis relative to the first flight path. While the missile travels the second flight path, the sensor receives signal identifying a target located at a position off-axis relative to the first flight path. The missile then adjusts the second flight path to direct the missile to the target. In an example embodiment, the first flight path is straight or arced, while the second flight path is u-shaped, corkscrew-shaped, or spiral-shaped.Type: GrantFiled: December 15, 2016Date of Patent: November 14, 2023Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Joseph D.

Patent number: 11175115Abstract: Techniques are provided for determination of a guided-munition orientation during flight based on lateral acceleration, velocity, and turn rate of the guided-munition. A methodology implementing the techniques, according to an embodiment, includes obtaining a lateral acceleration vector measurement and a velocity of the guided-munition, and calculating a ratio of the two, to generate an estimated lateral turn vector of the guided-munition. The method also includes integrating the estimated lateral turn vector, over a period of time associated with flight of the guided-munition, to generate a first type of predicted attitude change. The method further includes obtaining and integrating a lateral turn rate vector measurement of the guided-munition, over the period of time associated with flight of the guided-munition, to generate a second type of predicted attitude change.Type: GrantFiled: January 5, 2017Date of Patent: November 16, 2021Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: David J.

Publication number: 20200256643Abstract: A guidance system for deployment on-board a projectile includes a laser-seeking detector, an imaging device, and a control module. The laser-seeking detector is designed to detect the position of the projectile with reference to a laser spot on a target. The imaging device is designed to capture one or more images in front of the projectile. The control module is designed to control a flight direction of the projectile based on input received from the laser-seeking detector in a first mode, control the flight direction of the projectile based on input received from the imaging device in a second mode, and switch between the first mode and the second mode while the projectile is in flight towards the target. Both guidance technologies are leveraged to develop an improved guidance technique that provides highly accurate targeting and allows for a faster rate of fire to deal with multiple targets.Type: ApplicationFiled: February 12, 2019Publication date: August 13, 2020Applicant: BAE Systems Information and Electronic Systems Integration Inc.Inventors: David J.

Patent number: 9207051Abstract: An apparatus for deploying stowed control surfaces of a projectile is disclosed. The apparatus for deploying stowed control surfaces of a projectile includes a first and second hot gas generators, a first and second gas chambers, a piston wedge, a piston and a barrel. Initially, the first hot gas generator discharges a surge of hot gas into the first gas chamber. In response to the surge of hot gas being discharged into the first gas generator, the piston wedge displaces at least one of the control surfaces to break an environmental seal covering the projectile. After a predetermined amount of time has lapsed, the second hot gas generator discharges a surge of hot gas into the second gas chamber. The surge of hot gas displaces the piston and barrel for deploying the control surfaces completely.Type: GrantFiled: June 12, 2015Date of Patent: December 8, 2015Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Kenneth D.

Patent number: 8934776Abstract: A plurality of optical transmission sources provide data communication from a transmitting module to a common detector cooperative with a receiving module, the modules being subject to relative rotation about a shared axis. The detector can be located on the shared axis, each of the sources directing a beam onto the detector regardless of relative module orientation, and/or the light can be diffused, so that it is detected regardless of source and detector placement and relative module orientations. Transmissions can be distinguished according to synchronized timing, differing optical frequencies, differing baud rates, and/or differing circular polarizations. The detector can split the light into a plurality of beams which pass through different optical filters and are thereby distinguished. Cut-off circuits can prevent failed sources from transmitting. A diffused second light source and a second plurality of detectors can provide reverse communication from the receiving module to the transmitting module.Type: GrantFiled: April 5, 2011Date of Patent: January 13, 2015Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: James H.
