Abstract: Techniques are provided for steering vector generation. A methodology implementing the techniques according to an embodiment includes converting time domain data received from an antenna array to channelized frequency domain data. The method also includes receiving a request from a signal detection system, the request including a timestamp and duration of a detected signal of interest (SOI) and an indication that the SOI is pulsed or continuous. The method further includes generating, for a pulsed SOI, steering vectors to steer the antenna array to the pulsed SOI based on a segment of the time domain data stored in a first memory and identified by the time stamp and duration; and generating, for a continuous SOI, steering vectors to steer the antenna array to the continuous SOI based on a segment of the channelized frequency domain data stored in a second memory and identified by the time stamp and duration.

Abstract: A method of determining a schedule for a pointing device includes distributing targets among a plurality of groups and assigning schedules to the groups, after which the groups and group schedules are not modified. A partial pointing schedule is successively grown by selecting a list of remaining groups, and appending a best candidate sub-schedule for the list to the partial schedule. If a sub-schedule cannot be found for which the grown partial schedule meets all applicable requirements, the partial schedule is pruned to a previous state and a different, previously evaluated sub-schedule is appended to the pruned partial schedule to attempt re-growth. Groups, group schedules, lists, and sub-schedules can be selected according to values, dwell times, and/or windows of performance of the targets, groups, and sub-schedules. If no schedule is found that meets all requirements, a missed group can be excluded from the schedule.

Abstract: A communications circuit includes a first circuit block and a second circuit block. The first circuit block includes a first splitter, a first signal path coupled to a first output of the first splitter, a second signal path coupled to a second output of the first splitter, and a first switch configured to couple the second signal path to a third signal path or to couple a fourth signal path to the third signal path. The second circuit block includes a second splitter, a fifth signal path coupled to a first output of the second splitter, a sixth signal path coupled to a second output of the second splitter, and a second switch configured to couple the sixth signal path to the third signal path or to couple a seventh signal path to the third signal path. The third signal path extends between the first and second circuit blocks.

Abstract: A method of manufacturing a structurally competent, EMI-shielded IR window includes using a mathematical model that combines the Sotoodeh and Nag models to determine an optimal thickness and dopant concentration of a doped layer of GaAs or GaP. A slab of GaAs or GaP is prepared, and a doped layer of the same material having the optimal thickness and dopant concentration is applied thereto. In embodiments, the doped layer is applied by an HVPE method such as LP-HVPE, which can also provide enhanced GaAs transparency near 1 micron. The Drude model can be applied to assist in selecting an anti-reflective coating. If the model predicts that the requirements of an application cannot be met by a doped layer alone, a doped layer can be applied that exceeds the required IR transparency, and a metallic grid can be applied to improve the EMI shielding, thereby satisfying the requirements.

Abstract: Techniques to passively suppress or otherwise reduce stimulated Brillouin scattering (SBS) in a pumped fiber laser system. The system can be co-pumped with a tandem pumping technique, and counter-pumped with the direct diode pumping method. In an example, a pumped fiber laser system includes a fiber, a tandem pump, and a direct diode pump. The fiber has a core, an inner cladding around the core, and an outer cladding around the inner cladding. The tandem pump co-pumps light of a first wavelength in the inner cladding from a first end of the fiber, and the direct diode pump counter-pumps light of a second wavelength in the outer cladding from a second end of the fiber. A longitudinal temperature gradient can form along the fiber laser in response to this hybrid-pumping, which can combine both tandem and direct diode pumping.

Abstract: A feed forward guidance kit for a ballistic device that includes at least one optical imaging sensor, a processor that is operatively in communication with the at least one optical imaging sensor, and a feed forward guidance protocol that is stored on a computer readable medium and that is operatively in communication with the processor. When the at least one optical imaging sensor initially intercepts an aircraft at an initial location during combat, the feed forward guidance protocol instructs the processor to proactively calculate an anticipated second position of the aircraft as an orientation of the aircraft changes from an initial orientation to a translated orientation.

Abstract: Hybrid MB/ML techniques for automated printed circuit board (PCB) defect detection. In one example, a PCB inspection system implements a hybrid solution using model based (MB) and machine learning (ML) technologies to detect possible defects in a PCB via an automated image capture device and processing methodology. The processing methodology fuses features from MB and ML at the latent representation. An autoencoder can be used to learn the fused data by training a neural network to produce a reconstructed image that can be compared to an original image to generate a reconstruction error value. The system produces an output indicating detection of a defect in one or more features of interest based on the reconstruction error value transgressing a threshold value.

Abstract: A signal acquisition and tracking device includes an input configured to receive a global navigation satellite system (GNSS) signal, a software-based processor configured to execute software instructions to acquire the GNSS signal via the input and to generate, based on the acquired signal, one or more signal tracking parameters, and a hardware logic circuit operatively coupled to the processor. The logic circuit is configured to track the GNSS signal independently of the processor using the one or more signal tracking parameters generated by the processor. In some examples, the processor is configured to pull in and center the GNSS signal in time and frequency, and the logic circuit is further configured to track the pulled in and centered GNSS signal independently of the processor. In some examples, the processor acquires the signal and then hands-off control to the logic circuit for subsequent tracking of the signal.

Abstract: Techniques are provided for non-integer interpolation for signal sampling. A system implementing the techniques according to an embodiment includes a memory configured to store frequency values associated with an input signal sampled at a first clock rate. The system also includes a clock phase detector configured to detect phase alignment between a first clock signal associated with the first clock rate and a second clock signal associated with a second clock rate. The system further includes a read circuit configured to adjust an interpolation time interval in response to the detected phase alignment and to read the frequency values from the memory at the adjusted interpolation time interval. The system further includes a phase accumulator configured to accumulated phase as a sum of the frequency values read from the memory. The system further includes a waveform generator configured to generate an output waveform sample based on the accumulated phase.
