Welkin Sciences proposes investigating scintillation-hardening techniques applicable to DoD's strategic communication systems, focusing on hardening specific SATCOM links within the Ballistic Missile Defense System Communications Network that are of particular interest to DTRA and its customer, the Missile Defense Agency (MDA). These new scintillation-hardening techniques are based on computationa ...

Underground facilities provide concealment and protection for an array of activities conducted by US adversaries, including production, storage, and deployment of WMDs.  Communications with these subterranean facilities is a challenge at best. The current solution relies on conventional free-space RF radio links. However, RF propagation underground is not well understood and the variable and the ...

The Defense Threat Reduction Agency (DTRA) desires innovative technology solutions to link radiation detectors of various resolutions to accelerate and improve the efficacy of nuclear search operations. Global Technology Connection, Inc. (GTC), in collaboration with our Research Institute (RI) and industrial partners, proposes to develop a scalable, locally hosted data fusion algorithm to accurat ...

Welkin Sciences proposes to develop a comprehensive capability to formulate, analyze, simulate, prototype, and test scintillation-hardened receiver designs, including those enabled with built-in Matched Channel Filter (MCF) functionality. During Phase I, several MCF design architectures will be analyzed using CommLink, our high-fidelity computer simulation framework. Emulation of the type of down- ...

Welkin Sciences proposes to design and build a new fading channel simulator to be called the All-Digital Configu­rable Link Test Set (CoLTS–AD). It will be capable of emulating the full range of MIL-STD-3053 scintillating channel conditions needed to test all of DoD’s strategic communication systems. CoLTS–AD will support developmental and ac­ceptance testing of conventional communication ...

TDA Research, Inc. (TDA), designed, built, and tested a dense array of 100 very low cost infrasonic sensors. Due to their low cost (1/100x-1/10x the cost of other infrasound sensors), they can be economically deployed in very large numbers; such large arrays can gather more information than a few expensive sensors. They are sensitive from 0.1 Hz - 100 Hz down to 0.08 Pa. We tested the sensors in s ...

Colorado Engineering, Inc. and ISEA TEK (the CEI Team) propose research and development of an AI-enabled system that would be applied to the energetic testing system/database to enhance the characterization and test analysis capabilities. This would include automated data analytics to show historical trends, performance comparisons, data errors, and missing/ambiguous test results. The AI-Enabled T ...

During Phase I and a first Phase II, Welkin Sciences developed the Channel Realization Generator (CReG) algorithm, an enhanced functional replacement for the ACIRF code intended to be embedded into software link simulations and HWIL fading channel simulators. The proposed second Phase II effort will refine the CReG documentation and its software and firmware implementations. Many in the strategic ...

Micro-RDC has developed portable radiation effects test structures that scale to new process nodes.These structures will enable the investigation of the effects of radiation on the new technology from the material processing level as well as the circuit level.Fabricating the chosen structures and the refinement of software to extract the model parameters will be completed in this effort.A suite of ...

In response to SBIR Topic DTRA172-006, Welkin Sciences proposes to design and build a new all-digital fading channel simulator to be called CoLTSAD. This new simulator design will be the latest addition to our family of Configurable Link Test Sets (CoLTS). It will be capable of emulating the full range of MIL-STD-3053 scintillating channel conditions for all SATCOM frequency bands up to Ka-band. C ...
