Abstract: Techniques are provided for a transimpedance amplifier (TIA). A TIA implementing the techniques according to an embodiment includes a pre-amplifier stage configured to amplify an input signal. The pre-amplifier stage includes a first P-channel metal oxide semiconductor field effect transistor (MOSFET) (P1), a second P-channel MOSFET (P2), a first N-channel MOSFET (N1), and a second N-channel MOSFET (N2), coupled in series. The gates of P1 and N2 are driven by the input signal. The output of the pre-amplifier stage is provided at a coupling between the drain of P2 and the drain of N1. The pre-amplifier stage also includes an active resistor network configured to provide a variable resistance based on a provided current bias generated from a gain control signal. The active resistor network is coupled between the gate of P1 and the drain of P2. The variable resistance is used to control the gain of the pre-amplifier stage.

Abstract: A transceiver includes a radio frequency (RF) input, an RF channelized digital receiver, an RF wideband digital receiver, an analog-to-digital converter (ADC)/digital-to-analog converter (DAC), an RF channelized digital transmitter, and an RF output. The RF channelized digital receiver is configured to split an analog RF input signal into a plurality of sub-octave contiguous frequency band channels and to convert the channels to a plurality of first digital signals. The RF wideband receiver is configured to convert the analog RF input signal into a second digital signal. The ADC/DAC is configured to process each of the first and second digital signals to produce a plurality of third digital signals. The RF channelized digital transmitter is configured to convert each of the third digital signals into a plurality of analog output signals, to combine the analog output signals into an analog RF output signal, and to transmit the analog RF output signal.

Abstract: Correlation interferometry direction finding (CIDF) processes that significantly improve processing time and cut memory requirements relative to the current memory requirements are provided herein. The presently disclosed processes further may utilize only the real portion of the correlation coefficient of the RF signal to further increase processing speed and decrease memory requirements while simultaneously improving direction finding accuracy and reducing the number of wild bearings reported.

Abstract: A V-band clamp includes first and second clamp sections each having an arcuate shape with a first end, a second end, and inside surface defining a recessed channel. A hinge pivotably connects the second end of the first clamp section to the first end of the second clamp section. At least one fastener is configured to releasably connect the first end of the first clamp section to the second end of the second clamp section in a closed position. When the V-band clamp is in the closed position, each fastener extends through an opening in an end face on the first end of the first clamp section and into a bore in an end face on the second end of the second clamp section.

Abstract: A method of recognizing a pattern in a signal is provided. The method includes receiving, by a processor and at an input, the signal comprising data; converting, by the processor and based on a plurality of features, the data from the signal into a collection of features; identifying, by the processor, one or more feature-to-feature transitions between features in the collection of features; plotting, by the processor, a directed graph of each of the feature-to-feature transitions, wherein each unique feature in the collection of features is represented by a single vertex and each feature-to-feature transition is represented by a directed edge between two vertices weighted by a corresponding number of each of the feature-to-feature transitions; and detecting, by the processor, a pattern in the data by comparing the weight of each of the feature-to-feature transitions in the directed graph to a user-defined threshold.

Abstract: A thin film-retaining washer with custom geometry that may further provide for a simple press-on installation while maintaining retention of fasteners during assembly, shipping, handling, and/or use of associated systems. The present retaining hardware is easily manufactured from sheet or film materials with minimal post-processing and may be scaled and optimized for use with multiple size and style of fasteners. Further, the thickness profile of the thin film retaining hardware facilitates lobe spring deflection to further provide secure retention of the associated fasteners.

Abstract: A transceiver unit includes an enclosure, a first input port, a second input port, a first output port, and a second output port. A radio frequency (RF) pass-through path is within the enclosure between the first input port and the first output port and includes a gain module. The RF pass-through path is configured to receive a first RF signal at the first input port and to transmit a second RF signal at the first output port. The gain module is configured to amplify the first RF signal to produce the second RF signal. The transceiver unit further includes a transceiver path within the enclosure between the second input port and the second output port, the transceiver path including a signal processor.

Abstract: A platform with an auto-router takes into account non-navigation data, such as IR image sensor data or other non-navigation data to develop a route for a platform. The non-navigation data may be obtained from existing non-navigation sensors carried by the platform. The non-navigation data is fed to an auto-router that takes into account the non-navigation data to generate or dynamically alter a route for the platform.

Abstract: The system and method for chromatic correlation interferometry direction finding (CIDF) used to resolve ambiguities. Ambiguities are overcome by correlating over a range of frequencies. In some cases, multiple (i.e., 2 or more) frequencies or a continuous range of frequencies are used to make a more robust correlation manifold. As the complex response manifold is frequency dependent, using a set of two or more manifolds provides a significant reduction of false peaks.

Abstract: An alignment system for sensor or other electrical device filters rate data from gyroscopes and integrates the same to determine an alignment error state that is populated into a direction cosine matrix that pre-rotates measurement from a first electrical device into an estimated coordinate frame to determine a static alignment between first and second electrical devices or sensors. The system may be part of a countermeasure system on an aircraft. A first electrical device may be an inertial navigation system (INS), and a second electrical device may be an inertial measurement unit (IMU). The attitude of the IMU is used to translate the detected threats from the countermeasure system into a common reference frame of the INS.
