Abstract: A transmit drive circuit with high signal to noise and frequency agility. In one embodiment, a transmit circuit includes a digital to analog converter, an amplifier, and a signal to noise enhancer, the signal to noise enhancer being a nonlinear passive device that attenuates low-power signals while transmitting high power signals with little loss. The signal to noise enhancer may be fabricated as a thin film of yttrium iron garnet (YIG) epitaxially grown on a gadolinium gallium garnet (GGG) substrate, the GGG substrate secured to a microwave transmission line from the input to the output of the signal to noise enhancer, such that the thin film of yttrium iron garnet is close to the transmission line.

Abstract: A directed munition has a non-fragmentation casing, and an explosive within the casing that is configured to propel fragments out an opening of the casing when the explosive is detonated. The casing may be made of a material that does not produce lethal or injurious fragments when the explosive is detonated. The explosive may include an insensitive explosive portion that creates the shape of an explosive front, and a secondary explosive containing a more energetic explosive, which is closer to the fragments than the insensitive explosive portion. There may be more of the insensitive explosive than the relatively energetic explosive. The munition may have a ring that is operatively coupled to the fragments, to aid in directing the fragments out of the casing opening in a desired direction. The ring may be made of a material that does not produce injurious fragments when the explosive is detonated.

Abstract: A direct geolocation approach for estimating a location of a stationary emitter located on the Earth surface is provided. The approach uses data collected during a plurality of time periods including Time Difference of Arrival (TDOA) and Frequency Difference of Arrival (FDOA) measurements of a radar pulse sent from the emitter, and altitude measurements of an aircraft above the Earth surface. The approach includes estimating a location of the emitter for each of the time periods based on the TDOA, FDOA, and altitude measurements associated with a respective time period. The estimated location of the stationary emitter includes possible longitude and latitude of the emitter. The approach further includes averaging the estimated locations associated with the plurality of time periods to form an averaged estimated location of the emitter. A convenient example of the approach computes the location of the emitter based on the averaged estimated location.

Abstract: A waveguide mechanical phase adjuster includes at least one pair of dialectric rods nominally spaced ½ wavelength apart and inserted through a corresponding pair of holes (24, 26) in the wall of a waveguide (22). The holes are dimensioned so that they are in "cutoff" at the top end of the spectral band An adjustment mechanism sets the Insertion depth of the rods, which determines the amount of dielectric loading and, in turn, the insertion phase. Changing the insertion depth changes the dielectric loading, hence the insertion phase The ¼ wavelength spacing of the rods serves to cancel reflected energy. Additional pairs of dielectric rods can be similarly configured and actuated to increase the range over which the insertion phase can be adjusted. The waveguide mechanical phase adjuster is well adapted for use with power combiners to maintain tight phase coherence between channels.

Abstract: An optical fiber includes multiple cores (402, 404, 502, 504, 602, 604, 610) and a cladding (406, 506, 606). At least one of the multiple cores forms an optical waveguide and has an elongated cross-section with a narrower dimension in a fast-axis direction and a wider dimension in a slow-axis direction. The cladding surrounds the multiple cores and has a refractive index that differs from at least one refractive index of the multiple cores. The multiple cores could be stacked (502, 504; 602, 604) such that a first of the multiple cores is located at least partially over a second of the multiple cores in the fast-axis direction. The optical fiber could include an additional core within the cladding and having a substantially circular cross-section (610). The cores could be used to transport a high-power laser beam, an illumination laser beam, and an alignment laser beam. The optical fiber could have a length of at least two meters.

Abstract: A time- varying image is synthesized having at least one time-varying region of interest therewithin. The image is spatially modulated with an array of modulating pixels to form a modulated image. The array of modulating pixels has a modulator resolution. The modulated image is sensed with an array of sensor pixels. The array of sensor pixels has a sensor resolution. The modulator resolution is finer than the sensor resolution. Each sensor pixel corresponds to a plurality of modulating pixels. Said sensor pixel and said plurality of modulating pixels subtend the same region in the image. Outside the region of interest, the modulated image is synthesized at the sensor resolution and at a sensor video frame rate. Inside the region of interest, the modulated image is synthesized at the modulator resolution and at an effective synthesized video frame rate that is less than sensor video frame rate.

Abstract: A method includes simulating operation of a fiber optic gyroscope during a digital simulation. The simulation includes performing an iterative loop that includes simulating an intensity of light from a fiber coil of the fiber optic gyroscope and simulating operation of one or more control loops within the fiber optic gyroscope using the simulated intensity of the light. The intensity of the light is simulated using a sine/cosine function based on at least one angular rate-related effect injected into the simulation as a Sagnac phase shift. The simulated operation of a first of the one or more control loops attempts to reduce or eliminate the Sagnac phase shift. The method also includes storing, outputting, and/or using results of the simulation. The at least one angular rate-related effect could include rotation of the fiber coil and/or mechanical vibration of the fiber coil.
