The apparatus includes a single-fin coaxial-to-waveguide power combiner/divider, including a waveguide having one open end, one closed end, and two sides that are broader than two other sides; two fins in a plane within the waveguide, wherein the plane is configured to be parallel to the broader sides of the waveguide; and at least one coaxial input joined to each of the two fins. Signals may be applied to the at least one coaxial input joined to each of the two fins are in phase with each other, and a number of the at least one coaxial input joined to each of the two fins may include one of a same number and a different number.

Abstract: An apparatus includes a photonic integrated circuit having multiple cells. Each cell includes first and second antenna elements, where the first antenna element is configured to receive a portion of optical energy and the second antenna element is configured to transmit the portion of the optical energy. Each cell also includes a signal pathway configured to transport the portion of the optical energy between the first and second antenna elements. Each cell further includes a phase modulator configured to adjust a phase of the portion of the optical energy transported over the signal pathway. The apparatus also includes multiple wavefront sensors configured to measure wavefront errors in the portions of the optical energy. The apparatus further includes multiple phase controllers configured to adjust operation of the phase modulators in order to at least partially reduce the wavefront errors.

Abstract: An interactive orbital trajectory prediction system including a processor arranged to simultaneously display: i) a surface of the first primary body including the relative predicted trajectory of the object, ii) a surface of the second primary body including the relative predicted trajectory of the object, and iii) the barycenter of the two primary bodies, and the trajectory of the object with respect to the barycentric reference frame. The system includes an input device arranged to receive a user selection of a first sensor module of a plurality of sensor modules used to predict the trajectory of the object orbiting the primary body. The processor, in response to the user selection of the first sensor module, predicts the flight path of the object based on the first sensor module.

Abstract: An apparatus, and method of operating the same processes of LADAR data including iterating back and forth between target detection in a 2-D array having range and range rate dimension, and a 4-D array having azimuth, azimuthal velocity, elevation, & elevation velocity dimensions. The apparatus includes a receiver and a processor arranged to generate photo events including target signal photo events and background photo events, transform the photo events into the 2-D target tracking array including range and range-rate parameters and tag photo events determined to be 2-D target signal photo events. The processor transforms tagged photo events into the 4-D target and tags photo events determined to be 4-D target signal photo events.

Abstract: Embodiments regard feature fusion with uncertainty, such as for classification. A method includes altering, for each feature of features to be fused and based on a marginal uncertainty distribution corresponding to a feature of the features and the marginal uncertainty distribution accounting for uncertainty in measuring the feature, a marginal feature distribution of the feature resulting in respective marginal feature distributions that account for uncertainty, altering, based on a joint uncertainty covariance of the features, a joint feature covariance of the features resulting in a covariance that jointly accounts for feature covariance and uncertainty covariance, generating, based on the covariance that jointly accounts for feature covariance and uncertainty covariance and the respective marginal feature distributions that account for uncertainty, a joint density function that accounts for feature values and uncertainty, and classifying the features based on the joint density function that accounts for feature values and uncertainty.

Abstract: A nanocomposite optical ceramic (NCOC) material includes a plurality of coated (core-shell) nanoparticles having nanoparticles of a first material coated with a coating of a second material. The first material and the second material are mutually insoluble and each have a transmissivity of at least 80% for an intended wavelength. The first material and the second material have a difference in index of refraction of less than 25%. The first material and second material have grins with a diameter of less than 1/20th the intended wavelength. The coating of the second material on the nanoparticles of the first material is up to 50 nm thick. The NCOC contains no more than 0.01% voids per unit volume.

Abstract: A stored energy power source uses a wound-rotor induction machine (WRIM) to receive energy from an external source, store the energy in N energy storage elements (ESEs) via tertiary windings, and discharge the ESEs to deliver energy via a secondary winding to a load producing output. Each discharging ESE contributes to a total flux at the secondary winding to sum the individual ESEs voltages. These voltages can be stepped up or down by a transformation ratio between the secondary winding and each of the tertiary windings. A flywheel may be coupled to the secondary to store and delivery energy. Load factor power control can be used to stabilize the output voltage. The source may be configured to allow for the bi-directional flow of energy between an external power source, the ESEs, the flywheel and the load. The WRIM provides a safe, reliable and efficient system to provide high-level AC and DC output voltages.

Abstract: In a system for covert sensing and communications a broadband light source is encoded using spread spectrum waveform coding to spread a narrow-band signal over frequency. The modulated broadband light is suitably hidden in additional noise and then split into two portions, a first portion of which illuminates a target, and a second portion of which is delayed and provided as a local oscillator. Light reflected from the target is combined with the local oscillator, detected using heterodyne, homodyne or quasi-homodyne techniques, demodulated and decoded to estimate the phase of the reflected light relative to the transmitted light to provide fine range estimates for the target. Waveform coding allows for time-correlation of the transmitted and received coded waveforms to provide improved resolution for adjusting the delay of the local oscillator to improve the detection schemes. The waveform coding also provides a covert communications channel.

A method includes receiving, from a neuromorphic sensor, a time series of delta images, receiving auxiliary data indicating (i) an orientation, location, direction, or speed of the neuromorphic sensor, or (ii) metadata of the neuromorphic sensor, the auxiliary data associated with about a same time as the time series of images, operating, based on an image of the time series of delta images and auxiliary data of the auxiliary data associated with the image as occurring at about a same time, a first machine learning (ML) model resulting in a low-resolution image, and operating, based on the low-resolution image, a second ML model resulting in a high-resolution image, the high-resolution image of a type different than that produced by the neuromorphic sensor.
