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.

摘要： A device, method, and system for the detection of ribosome inactivating protein activity, including the ricin toxin, in a sample. According to one embodiment, the ribosome inactivating protein in the sample removes an adenine from a labeled DNA substrate to create an abasic site. An AP lyase can then cleave the DNA substrate at the abasic site, allowing the fluorophore located at or near one end of the DNA substrate and the quencher at or near the other end of the DNA substrate to spatially separate. Once the fluorophore and the quencher are sufficiently separated, the fluorophore will emit a fluorescence signal. Increasing fluorescence, indicating ribosome inactivating protein activity, will be monitored in real time using a detection system.

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： A transmit-receive radar system having multiple sub-apertures aligned in an offset, off-centered cross pattern that allows for searching of a sub-aperture pattern for the peak response without having to retransmit beams. The placement of the physical apertures combined with the use of MIMO operations provides a non-uniform distribution of virtual sub-apertures that suppresses ambiguous grading lobes and maintains angle resolution in a manner equivalent to that of non-MIMO approaches. As a result, target detection is enabled within a significantly larger angular area than in a non-MIMO configuration.

摘要： A system and method for phased-array radar that is capable of accurate phase-only steering at any unambiguous angle is provided. In various embodiments, system and method that compensates for the varying effective element spacing of phased array radar, which occurs as a result of transmitting a wideband signal with phase shifters operating at a fixed phase, by interpolating and resampling across all elements, per frequency, to generate a desired effective spacing between the elements.

摘要： A radar system includes an image forming circuit that provides a two-dimensional image of an operating environment. The image includes pixel elements representative of the operating environment. The system includes at least one filter configured to convert the two-dimensional image into a clutter classification map of clutter regions. A predetermined number of clutter regions are selected as training cells for a predetermined cell-under-test (CUT). A space-time adaptive processor (STAP) is configured to derive a weighted filter from training cell data. The STAP applies the weighted filter to a digital return signal associated with the predetermined CUT to provide a STAP-filtered digital return signal having the clutter signal components substantially eliminated therefrom.

摘要： Various embodiments and implementations herein are directed to an aerosol and vapor sampling device that has a nozzle capable of focusing/concentrating the sampled particles by accelerating them in a narrow jet and driving the particles into an impaction well containing a collection substrate. The aerosolized particles, aerosolized droplets, and chemical vapors are retained by using a porous collection substrate, having substantial depth and mounted on a porous backing, such as a screen. This configuration allows a minor air flow through the collection substrate. This minor flow allows a well impactor to retain intercepted aerosolized particles. It also improves the inlet's ability to collect and retain chemical vapors or liquid aerosol droplets that are partially filtered and captured in the substrate's matrix.

摘要： The present invention is directed to an antenna system and a method that is configured to compute calibration element voltage gain patterns as functions of a digital antenna model and a plurality of complex beamformer voltages, determine calibration through path transfer functions from the plurality of complex voltages, and remove the calibration element voltage gain patterns from the calibration through path transfer functions to determine a beamforming network transfer function. The beamforming network transfer function and the far-field element voltage gain patterns are combined to obtain a system transfer function used to revise a calibration table.
