摘要： A synthetic aperture radar's surveillance is defeated by electronic camouflage that employs a protective shield to cover an intended target. The shield intercepts and modifies the interrogating radar pulses by modulating incident radar pulses to produce radar echoes shifted in Doppler frequency, whereby the returned echoes give a false depiction of the target, even to smearing the radar display. New structures are presented that exhibit variable reflectivity and variable dielectric characteristics of particular use in the foregoing and other electronic systems.

摘要： A knowledge driven composite design optimization process for designing a laminate part includes steps for generating a globally optimized 3-D ply definition for a laminate part, and modifying the 3-D ply definition to include features of the laminate part, where the generating and modifying steps are parametrically linked to one another and are performed in the recited order. Preferably, the generating step includes substeps for determining connectivity between a plurality of regions defining the laminate part, subsequently generating ramp features detailing interconnection of the regions defining the laminate part, and displaying views and corresponding tabular data describing the laminate part and illustrating both inter-region connectivity and the ramp features as specified by a user. A knowledge driven composite design optimization system and associated computer memory for operating a general purpose computer as a knowledge driven composite design optimization system are also described.

摘要： A method for producing a spatially stratified Optical System includes the steps of a) selecting a suitable, spatially stratified profile of index of refraction to achieve an optical system having a desired performance; b) selecting an atomic/molecular species having a suitable index of refraction in a desired operational wavelength band; c) forming sub-micron pellets of the species; and d) placing the pellets into a host material while controlling the density of the placement. The density is varied to achieve a local index of refraction value for the optical system in accordance with the selected stratified profile. The wavelength regime the optical system is designed for is much greater than the characteristic scale of stratification, which in turn is much greater than the spatial size of the pellets. The optical system is much greater than the wavelengths in the wavelength regime.

摘要： The method and associated apparatus of the present invention decodes digital signals by appropriately weighting the respective noise portions of the two phase segments generated by the detector, such as an APD in an optical communications system, such that the digital signal can be reliably decoded despite the presence of multiplicative noise induced by the detector. The detector detects a digitally encoded communications carrier signal having a waveform defining first and second portions. The detector then generates an electrical signal in response to the digitally encoded communications carrier signal. The electrical signal has two phase segments, namely, one phase segment corresponding to the first portion of the digitally encoded communications carrier signal and another phase segment corresponding to the second portion of the digitally encoded communications carrier signal. Each phase segment also includes a respective noise portion. The optical decoding method and apparatus determines a weighting factor based upon the respective noise portions of the two phase segments. Thereafter, at least one phase segment is weighted by the weighting factor. For example, the noisier phase segment can be attenuated by the weighting factor. A decoder can then identify the logic level of the digital signal based upon the two phase segments as weighted by the weighting factor.

摘要： An imaging apparatus for aiding landing of aircraft in weather conditions obscuring a pilot's view of a runway. The apparatus comprises a plurality of LED assemblies which are disposed along the runway. Each LED assembly includes a plurality of LEDs, a receiver and a plurality of drivers responsive to the receiver for energizing the LEDs. The LEDs of each LED assembly are pulsed on by signals from a transmitter disposed adjacent an end of the runway. The transmitter also sends synchronization signals to a receiver located on board the approaching aircraft. The receiver on the aircraft is coupled to a processor which uses the synchronization signals to determine when the LEDs are energized and when they are not energized. The processor controls a CCD camera mounted on the aircraft so as to obtain an unobstructed view of the approaching runway. The processor controls the CCD camera such that the camera takes images (i.e., frames) while the LEDs are pulsed on and also while the LEDs are off. The frames with the LEDs off are then digitally subtracted from the frames taken while the LEDs were energized to produce enhanced images which are output to a visual display on-board the aircraft and which do not include the objectionable radiant background information. In an alternative embodiment a plurality of independent groups of LED assemblies are controlled in accordance with separate synchronization frequencies. The pilot is instructed which synchronization frequency to select, and only the LED assemblies corresponding to the selected group appear as being continuously illuminated on board the visual display on the aircraft.

摘要： An apparatus and method for forming an aircraft fuselage having at least one doubly curved portion. A plurality of fuselage panels are extruded with integrally formed stiffening portions extending preferably longitudinally the full length of each fuselage panel. The stiffening portions are further formed so as to be generally parallel to one another. The fuselage panels are then formed into skin panels having a desired curvature and trimmed into gores, and the stiffening portions trimmed at end portions that run out toward longitudinal edges of the panels. When adjacent panels are affixed together, the stiffening portions run out toward longitudinal edges of adjacent panels. The longitudinal edges are secured by splice longerons which are riveted or welded to the longitudinal edges of the skin panels. Independent fastening members are then secured to the stiffening portions and the splice longerons at the points where the stiffening portions run out to positions closely adjacent the splice longerons. The apparatus and method permits aircraft fuselages having doubly curved portions to be formed from extruded panels which is more cost efficient and makes use of a greater percentage of raw materials than conventional methods of machining such panels out of non-near-net stock such as plate.

摘要： Process for bonding a copper substrate to a tungsten substrate by providing a thin metallic adhesion promoting film bonded to a tungsten substrate and a functionally graded material (FGM) interlayer bonding the thin metallic adhesion promoting film to the copper substrate. The FGM interlayer is formed by sintering a stack of individual copper and tungsten powder blend layers having progressively higher copper content/tungsten content, by volume, ratio values in successive powder blend layers in a lineal direction extending from the tungsten substrate towards the copper substrate. The resulting copper to tungsten joint well accommodates the difference in the coefficient of thermal expansion of the materials.
