    摘要: A spiral antenna, comprising a first arm and a second arm. The first arm and second arm are interlaced with each other. Each arm has a plurality of turns comprising an inner subset of circular turns, and an outer subset of turns, electrically coupled to the inner subset, having a shape with only four lines of symmetry. An array of such spiral antennas disposed a substrate that extends in a direction of a longitudinal axis and having a round cross section in a plan transverse to the longitudinal axis.

    摘要: A method of processing a radar hit from an object using, for each of a plurality of cells, a signal strength threshold, a hit rate threshold, a time of last detection; and receiving, for one of the plurality of cells corresponding to the object, a measured signal strength, a measured hit rate and a time of measurement. The object is identified as clutter if the measured hit rate is greater than the hit rate threshold, and the measured signal strength is less than signal strength threshold. The signal strength threshold is above a conventional CFAR signal threshold. Measured Doppler strength may also be used to identify clutter. Identification can be determined using Doppler-polarity-specific data values. The hit rate and the mean Doppler speed of the one of the plurality of cells can be updated using a running average.

    摘要: The present invention is directed to a system and method for providing an estimated design specification as a function of a number of spatially separated far-field measurements and a predetermined design specification. The predetermined design specification corresponds to an antenna being in a properly configured and a properly excited state. The system maps the spatially separated far-field measurements into an estimated far-field antenna pattern of the antenna based on the estimated design specification. The system provides difference data based on a comparison of the predetermined design specification and the estimated design specification and can adjust the electrical excitation signals of the antenna in accordance with the difference data or the estimated far-field antenna pattern.

    摘要: Methods and systems for detecting chemical and biological agents using oligonucleotide aptamers. A sensor includes a detection aptamer that has a binding domain for the chemical or biological agent, and is bound to fibers of a textile such as a patch or article of clothing. The detection aptamer can be stabilized and enhanced through a stabilization agent such as trehalose or through binding to a nanoparticle which is then bound to the fiber. Binding of the chemical and biological agent of interest to the detection aptamer can be reported to the user or wearer of the textile in a variety of ways, including visually and electrically.

    摘要: Methods and systems for scalable high-performance embedded computing architectures. According to an embodiment, a scalable high-performance embedded computing system increases computational capability within the restrictive size, weight, and power constraints of systems such as the external pod payloads of unmanned aircraft systems, among many other possible systems. The core computer capability can be placed in various environments, and according to one embodiment utilizes a flight-certified aeronautics pod that is scalable in length. The scalable HPEC system can be connected to external data sources, or the nose and tail can be made of Radio Frequency transparent material, enabling the use of various RF sensing technologies within the same aeronautics enclosure. According to an embodiment, a lightweight, thermally-efficient conduction cooled chassis supports the required board and interface hardware.
