Abstract: A system for imaging includes both integration time gain and readout gain. It has a plurality of pixels comprising a frame, each pixel has a direct injection input with two Sample-and-Holds (SHs); a short integration time output; and a long integration time output. The integration time gain extends the range to higher fluxes with shorter integration times. A Read Out Integrated Circuit (ROIC) includes at least one column cell having a gain selection component where each of the short integration time output and the long integration time output are compared to a threshold, producing gain bits and an Analog to Digital Converter (ADC) producing data bits.

Abstract: GaAs IR window slabs having largest dimensions that are greater than 8 inches, and preferably greater than 12 inches, are grown using the Horizontal Gradient Freeze (HGF) method. Heat extraction is simplified by using a shallow horizontal boat that is only slightly deeper than the desired window thickness, thereby enabling growth of large slabs while also minimizing material waste and fabrication cost as compared to slicing and shaping thick plates from large, melt-grown boules. Single crystal seeds can be used to optimize the final orientation of the slabs and minimize secondary nucleation, thereby maximizing yield. A conductive doped GaAs layer can be applied to the IR window slab to provide EMI shielding. The temperature gradient during HGF can be between 1° C./cm and 3° C./cm, and the directional solidification can be at a rate of between 0.25 mm/h and 2.5 mm/h.

Abstract: The system and method described herein utilizes spectral data, spatial data, and temporal data, simultaneously, to provide an improved clutter suppression technique to provide an improved output for feeding into an object detection protocol. This clutter suppression technique that uses spectral data, spatial data, and temporal data, simultaneously, results in improved processing capabilities by reducing the amount of processing power needed to obtain the resultant output. The present disclosure utilizes particular protocols and processes to effectuate the usage and processing of spectral data, spatial data, and temporal data, simultaneously.

Abstract: Techniques are provided for mitigating interferometric angle ambiguity. A methodology implementing the techniques according to an embodiment includes measuring a differential phase of a signal received at an interferometer baseline; calculating a Gaussian conditional probability of an angle of arrival of the signal based on the differential phase; calculating an angular position probability of an object in a target reference frame based on the conditional probability; aggregating the angular position probability with previously calculated angular position probabilities (based on previously selected baselines) to generate a current angular position probability; selecting a next baseline and iterating the process to calculate a next angular position probability; and selecting an angular position probability of greatest likelihood, from the current and previously calculated angular position probabilities, based on an amplitude of the Gaussian distributions, such that the selected angular position probability is associated with a disambiguated angular position of the object.

Abstract: A guided vehicle that includes a body, a propulsion system operably engaged inside of the body, a housing operably engaged with the body and encasing a guidance device inside of the housing, a viewing window of the guidance device, and a cover moveably engaged with the housing, wherein the cover is moveable between a pre-flight configuration and a flight configuration. In the pre-flight configuration, the cover covers the viewing window. In the flight configuration, the cover is configured to expose the viewing window in the flight configuration in response to an impulse of acceleration generated by a launch of the guided vehicle.

Abstract: A collet for multiple wire elements is disclosed. In an example, the collet has a body made of a polymeric material and extends along a central axis from a first end to a second end. The body defines a first passageway extending axially through the body, the first passageway in communication with the environment via a first insertion opening extending along an entire length of the first passageway. The body defines a second passageway extending axially through the body and in communication with the environment along an entire length of the second passageway via a second insertion opening, the second passageway spaced circumferentially from the first passageway. When installed, the collet frictionally engages wire elements when a first wire element is seated in the first passageway and a second wire element is seated in the second passageway.

Abstract: A programmable transimpedance amplifiers (TIA) having T-network feedback architectures for achieving varying levels of gain based on a magnitude of an input current signal. TIA includes an operational amplifier (op-amp), a first or T-network feedback architecture that operatively connects with the op-amp at a first input terminal of the op-amp and the output terminal of the op-amp, a second feedback architecture that operatively connects with the op-amp at the first input terminal of the operational amplifier and the output terminal of the operational amplifier, an input voltage source architecture that operatively connects with a second input terminal of the operational amplifier, and at least one controller that operatively connects with each of the first feedback architecture, the second feedback architecture, and the input voltage source architecture to switch specific architectures between operative states and inoperative states to achieve a predetermined fixed output bias voltage from the operational amplifier.
