Publication number: 20210270570Abstract: The system and method of directed navigation using an augmented semi-active laser seeker to provide initial altitude measurement and command denotation information for rounds. Using on-board sensors and communications links between members of a swarm, numerous targets can be engaged more quickly and precisely. The LCSAL can act as 3D LIDAR where the LCSAL's spatial resolution and the associated image from the imager can be correlated to the LCSAL pixel by pixel as time of arrival. The rounds trajectory can be refined due to coupling with accurate Target ID to provide optimum command detonation for specific target types.Type: ApplicationFiled: February 28, 2020Publication date: September 2, 2021Applicant: BAE SYSTEMS Information and Electronic Systems Integration Inc.Inventors: Michael J.

Patent number: 11047958Abstract: The system and method for target identification using a comparatively low resolution imager combined with a 3D LIDAR on-board a round. This system and method are applicable to any round looking for a 3D target ID. A round, as used herein, may be a weapon, a projectile, a ballistic, a bullet, a munition, a guided weapon, or the like. By coupling a fiber laser of a LIDAR with a piezoelectric oscillator, or actuator, to scan a target and an avalanche photodiode (APD) detector array, or other high resolution sensor, target dimensional information can be used to increase the probability of an accurate target ID.Type: GrantFiled: March 13, 2020Date of Patent: June 29, 2021Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventor: Michael J.

Publication number: 20210190459Abstract: The system and method of swarm navigation using a follow the forward approach. Using on-board sensors and communications links between members of a swarm, numerous targets can be engaged more quickly and precisely. In some cases, a designator is used to help a forward of the swarm navigate to a target using image-based navigation up until terminal guidance is used. A cascade of messages are projected back to a following round so that, each member of a swarm can determine a best target/round match and provide real-time, up-to-date information regarding targets' locations and each round's location, range to target, target selection, and the like.Type: ApplicationFiled: December 18, 2019Publication date: June 24, 2021Applicant: BAE SYSTEMS Information and Electronic Systems Integration Inc.Inventors: Michael J.

Patent number: 10823611Abstract: A light sensing apparatus includes: an arrangement of light sensing pixels, one or more pixels each associated with a noise floor and able to detect a triggering level of incoming light above the noise floor from a corresponding portion of a scene; readout circuitry to process and reset the triggering pixels; and an automatic gain control (AGC) to raise the noise floor of one or more pixels. Sometimes, the light sensing apparatus is part of a seeker that includes control circuitry to dynamically control the AGC to raise the noise floor of one or more pixels by an adjustable amount that varies in relation to the distance between the seeker and an intended target. Sometimes, the control circuitry dynamically controls the AGC in response to a concurrent triggering of two or more triggering pixels. or in response to a gain schedule corresponding to guiding the seeker to the intended target.Type: GrantFiled: September 12, 2018Date of Patent: November 3, 2020Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Dimitre P.

Publication number: 20200318967Abstract: A system for finding up in a projectile flight relative to earth. The system having a transmitter which transmits polarized reference signals to a guidance sub-system on the projectile. The guidance sub-system includes a magnetometer and polarized and non-polarized receivers. Measurements from the magnetometer are used to determine a general up direction. The polarized and non-polarized receivers are arranged such that, during rotation of the projectile, reference signals received by the polarized receiver modulate whereas reference signals received by the non-polarized receivers are unaffected. A ratio of the strengths of the signals received by the polarized and non-polarized receivers determines alignment of a vertical axis. From the general up direction and alignment of the vertical axis, a precise up direction of the projectile in flight relative to the earth can be determined.Type: ApplicationFiled: April 4, 2019Publication date: October 8, 2020Applicant: Bae Systems Information and Electronic Systems Integration Inc.Inventor: Michael J.

Publication number: 20200271421Abstract: The present system estimates target motion with nonzero acceleration (including maneuvering uncertainty) using angle only (AO) measurements. The present approach employs a mixed coordinate system framework by combining modified spherical coordinate (MSC) system and Reference Cartesian Coordinate (RCC) system to keep accurate information flowing from one frame to the other while eliminating the numerical sensitivity of the angle measurements to the TSE vector. This integrated coordinate systems framework is achieved due to the state vector information of two frames (RCC and MSC) is effectively preserved between processing cycles and state vector transformation steps. The AO TSE architecture and processing schemes are applicable to a wide class of passive sensors.Type: ApplicationFiled: February 26, 2019Publication date: August 27, 2020Applicant: BAE SYSTEMS Information and Electronic Systems Integration Inc.Inventors: Quang M.
