Patent number: 10798309Abstract: A method and apparatus for calculating and accounting for non-uniformity of pixels within an infrared (IR) focal plane sensor utilizing an infrared light emitting diode (IR LED) to wash out environmental infrared light is provided. The IR LED may back propagate through an optical path of an IR sensor to illuminate pixels on a focal plane array, thereby providing data by which the non-uniformity offsets may be calculated and removed for normal operation of the IR sensor.Type: GrantFiled: November 21, 2018Date of Patent: October 6, 2020Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Michael N. Mercier, Lucas Lawrence-Hurt, Joseph M. Schlupf

Patent number: 10298817Abstract: An optical system recycles heat from a cooler coupled with an image sensor across a heat transfer element in order to warm and de-ice a window. The optical system may be implemented in high altitude or space vehicles/platforms, regardless of whether manned or unmanned, and the window may be outwardly facing relative to the vehicle/platform so at to allow electromagnetic radiation to pass therethrough onto the image sensor. The optical system enables the reduction of size, weight, and power by recycling heat exhausted from the cooler to warm the window, thus eliminating the need for a separate de-icing system or device for the window.Type: GrantFiled: June 19, 2018Date of Patent: May 21, 2019Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Joseph M.

Patent number: 10295402Abstract: A method of determining the point source quality of a set of pixels associated with a detected energy signature is discussed that pre-records ideal test point source signatures at various sub-pixel locations and radiant intensities throughout the overall sensor field of view in a focal plane array, determines the sub-pixel location of an observed source, and compares the signature at a pixel of the observed source to the pre-recorded “ideal source” signatures at the determined sub-pixel location. to determine point source correlation.Type: GrantFiled: October 20, 2015Date of Patent: May 21, 2019Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Michael N.

Patent number: 10157473Abstract: An mechanism for range estimation mapping that includes creation of a world map on an azimuth/elevation (AZ/EL) grid, relation of the grid to an earth-fixed north, east, and down (NED) coordinate system through an address table, and association of each pixel in each frame, by a programmable device, with an entry from the address table in order to determine a range is discussed. The associations may be repeated for each frame while an updated world map and address table are generated. When an updated address table is complete, the process may begin anew using the updated data.Type: GrantFiled: October 20, 2015Date of Patent: December 18, 2018Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Kevin C.

Patent number: 9989334Abstract: Techniques for tracking a straight line object by creating a detection envelope between two detections selected from temporally-discontinuous frames are discussed. The detections within the detection envelope can then be analyzed in order to determine whether they are associated with a straight line track between the outer detections of the envelope. Techniques for identifying a launch-flash are also discussed. Potential launch flashes are checked for energy duration, intensity and spectral ratio. Techniques for detecting a hostile fire based on a single-frame detection are additionally detected. Based on a frame length of the detection, it can be determined whether the detection correlates to a hostile fire.Type: GrantFiled: October 20, 2015Date of Patent: June 5, 2018Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Kevin C.

Patent number: 9977961Abstract: Exemplary embodiments provide a method, a system, and a computer readable medium for maintaining detection capability when a frame is corrupted. A plurality of data points of a multispectral gain in a frame is monitored. It is determined that the frame is corrupted by analyzing the plurality of data points. When the frame is corrupted, a single spectrum threat detection system is used instead of a multispectral threat detection system.Type: GrantFiled: October 20, 2015Date of Patent: May 22, 2018Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Michael N.
