Abstract: The system and method non-linear optical mapping of a detector array to expand the field of view. Outer edges of the sensor array having lower resolution spatial resolution in exchange for an expanded field of view. A lens is used to distort incoming signals to provide the expanded field of view and a processor is used to remove the distortion to provide the actual spatial angles for the incoming signals suing a look up table or an algorithm. The lens may create radial or linear distortion.

Abstract: The present disclosure provide a device, system, and method for generating, in an electrical device, a 1 bit or a 0 bit that is received in a switching circuit powered by a battery. The device, system, and method generates, in the switching circuit, a negative bias voltage and a positive bias voltage. The device, system, and method transmits the negative bias voltage and the positive bias voltage to a power amplifier. The device, system, and method turns the power amplifier from an off-state to an on-state in response to receiving the negative bias voltage. The device, system, and method amplifies, with the power amplifier, a power signal moving through power amplifier when the amplifier is in the on-state.

Abstract: An array antenna has a plurality of antenna unit cells arranged in rows and columns, or in another configuration. Each unit cell from the plurality of unit cells includes a circularly polarized radiator and a balun. The array antenna further includes a reactive element or a circuit element (such as a capacitor or resistor or even an inductor) on the circularly polarized radiator that is coupled an adjacent unit cell in one of the row and the column. A spacing distance between adjacent unit cells coupled via the circuit element that is at most half of a wavelength at a frequency maximum of the array antenna, wherein the spacing distance reduces likelihood of grating lobes.

Abstract: A modified GNN/DA subsystem processes angle only measurements from at least two sensors (but can be replicated to n sensors using a similar track fusion framework per sensor as a local track center and then fusing them via a multiple local track fusion architecture) to reconstruct a complete battle space picture consisting of multiple moving targets. In some cases, the sensor is an EO/IR camera and the moving targets are UAVs. The modified GNN/DA is used as part of a Fire Control Solution (FCS) either implemented on a ground-based vehicle or on-board a projectile.

Abstract: A communications receiver. One example embodiment is a system-in-package (SIP) device, which includes a three-dimensional interposer, a first bandpass filter integrated into the three-dimensional interposer, a first integrated circuit chip on the three-dimensional interposer, a second integrated circuit chip on the three-dimensional interposer, a second bandpass filter integrated into the three-dimensional interposer, and a third bandpass filter integrated into the three-dimensional interposer. The first integrated circuit chip includes a balanced amplifier that receives a first filtered signal and suppress distortion products. The second integrated circuit chip includes a first mixer and a second mixer. The first mixer receives an output of the balanced amplifier and mixes the output with a first oscillator signal. The second bandpass filter receives an output from the first mixer and generates a second filtered signal. The second mixer receives the second filtered signal and mixes the second filtered signal with a second oscillator signal.

Abstract: The system and method of global positioning system (GPS) anti-jam (AJ) AJ antennas utilizing a circular array of patch antennas. In some cases the circular array is conformal. The elements are single patch, dual band (L1/L2) and are linearly polarized. A mode former and progressive phase tapers are used.

Abstract: A system and associated method determines the characteristics of an electric network including distance to a fault through the use of a power divider and a measuring device that measures a quantity from which voltage magnitude can be determined. The measuring device may be a power detector. The power detector may include a power meter to measure voltage and/or a power sensor to measure amplitude. Then, the results from the power detector are used in conjunction with a Hilbert transform to estimate the phase associated with at least two voltage magnitudes when a combined signal is a minimum phase signal.

Abstract: The system and method for lightweight spiral antenna array packaging uses a foam core and metallic elements such that the foam core is machined to accept the folded metallic elements to create a compact and light weight assembly. The assembly can be bonded to other assemblies to form arrays. The array is then encapsulated in a prepreg fiberglass skin with a conductive layer of fabric/screen therein.

Abstract: A laser warning receiver system and method having at least four optical components mapped to a photodetector array to provide for omnidirectional detection of incident laser light. In some cases, a fifth optical component is mapped to the central portion of a photodetector array to provide hemispheric detection of laser light. The laser warning receiver system is configured to detect laser light in the NIR, SWIR, MWIR, and/or LWIR range using a single photodetector array and ROIC.

Abstract: A system and method for nulling or suppressing interfering signals directed toward moving platforms based, at least in part, on dynamic motion data of the moveable platform is provided. The system may be an interference nulling system carried by a moveable platform and may include an antenna array including two or more antenna elements that generates at least one initial steerable null radiation pattern, dynamic motion data logic that determines dynamic motion data of the moveable platform; and update logic that updates the at least one initial steerable null radiation pattern based, at least in part, on the dynamic motion data. The at least one updated steerable null radiation pattern is directed toward a direction from which interfering signals are being transmitted from an interfering signal source.
