It is a finding of this invention that the LADAR will improve the spatial resolution by a factor of five over typical missile defense IR seekers using a common aperture. The LADAR provides a 3D angle, angle, range (AAR) image for each laser pulse which is used to extract the precise target state vectors.Type: GrantFiled: December 31, 2002Date of Patent: April 12, 2005Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Michael E.

Patent number: 6856272Abstract: Methods and apparatus for early detection and identification of a threat such as individuals carrying hidden explosive materials, land mines on roads, etc. are disclosed. Methods comprise transmitting radar signals in the direction of a potential threat, measuring the energy in reflected signals, dynamically generating a threat threshold value from signals received from multiple areas and comparing the energy in the reflected signals corresponding to different areas to the generated threat threshold value. The threat threshold value may be generated by averaging the weighted reflected energy measured from different areas during a single scan of a region including the different areas. The contribution to the threshold from different areas is weighted in some embodiments as a function of the distance from the transmitter and/or receiver to the particular area. Analysis of areas and treating different areas as segments facilitates accurate analysis and display of threat information.Type: GrantFiled: December 8, 2003Date of Patent: February 15, 2005Assignee: Personnel Protection Technoloties LLCInventors: Arthur C.

Publication number: 20040239549Abstract: A method, apparatus, and computer readable medium are provided for creating a quantitative, three-dimensional representation of a surface of a human subject. Data representing a physical appearance of a human subject is gathered using inverse synthetic aperture radar. A source signal is directed toward the human subject as the target rotates through a range of motion and a return signal is collected. The returned signal is transformed into a quantitative representation of the surface data. The quantitative representation can be added to an archive or can be checked against an archive to determine if the human target is indexed in the archive.Type: ApplicationFiled: May 30, 2003Publication date: December 2, 2004Inventors: Douglas P.

Patent number: 6825791Abstract: A deceptive signature broadcast system for an aircraft or other emissions generating asset for generating an emissions pattern for masking the normal emissions signature of the aircraft or asset, and protecting it from emissions tracking intercept vehicles such as Infrared tracking missiles; the system includes at least two beacons mounted in a spaced apart arrangement orthogonal to the desired zone of protection, and bracketing the asset, such as on opposite wingtips of the aircraft for fore and aft protection; the beacon set is modulated from one end to the other with a sweeping pattern of emission intensity, deceptively indicating to the intercepting vehicle a lateral component of motion of the aircraft away from its true relative position within the intercept vehicle's field of view, thereby inducing the intercept vehicle to adopt an erroneous and exaggerated lead angle and course correction that results in a missed intercept trajectory.Type: GrantFiled: June 30, 2003Date of Patent: November 30, 2004Assignee: Sanders Design International, Inc.Inventors: Royden C.
