The high energy physics (HEP) community, the scientific and medical communities and the public at large, require the availability of high sensitivity photo- sensors with improved spatial and temporal resolution that can be scaled to large areas, and manufactured in a robust, durable, and compact package at a low cost. Phase I successfully demonstrated the underlying enabling scientific and techni ...

Physical Sciences Inc. has successfully demonstrated the operational capability of a filament wound composite case designed to mitigate against slow cook-off, fast cook-off, bullet and fragment impact threats for solid rocket motor (SRM) systems. The implemented manufacturing, quality control and assurance processes enable production of small and large diameter motors to satisfy strategic and tact ...

The advent of sensor networks to gather atmospheric data for weather and climate prediction on large spatial and temporal scales is crucial to the advancement of our understanding of many important processes that make up such predictive models. The height of the atmospheric boundary layer, for example, is used to parameterize boundary layer transport in numerical weather prediction models and boun ...

As computational density for high-performance computing and big-data services continues to scale, performance scalability of next generation computing systems is becoming increasingly constrained by limitations in memory access, power dissipation and chip packaging. The processor-memory communication bottleneck, a major challenge in current multicore processors due to limited pin-out and power bud ...

Physical Sciences Inc. (PSI) proposes to utilize a ground-based simulation facility based upon its patented FAST technology to obtain critical data necessary to validate and extend the capabilities of the MDA’s high altitude plume code, SOCRATES-P, to model plume signatures with high fidelity. In Phase I PSI demonstrated the model validation approach by measuring the velocity dependent cross sec ...

Physical Sciences Inc. (PSI) proposes to develop, evaluate, and test its candidate architecture for multistatic radar for Ballistic Missile Defense (BMD). The innovative architecture is based on nonlinear Kalman Filter data fusion with multiple dynamical models with compensation for ship platform errors, and a parallelized multiple hypothesis tracking/association methodology (MHT). The key result ...

Over many data collection campaigns, a large number of propulsion related signature events have been observed across an extended range of the electromagnetic spectrum. The current suite of plume modeling tools contains the basic framework for flowfield and signature generation, but lacks the underlying physical mechanisms and supporting property databases to properly account for alternate waveband ...

As the United States makes strides in developing, testing, and deploying missile defense technology, the human element remains core to the integrated, layered ballistic missile defense system (BMDS) architecture. Human operators oversee the command and control at the system, component, and element level across a vast array of networked ground-, sea-, and space-based sensors and interceptors to eff ...

Active phased array radars are expensive and solid state power and low noise amplifiers are a major component of that expense. Sharing these amplifiers amongst many antenna elements is a strategy for reducing expense. However, in order to maintain independent phase control, the phase shifter and its attendant insertion loss must then be inserted between the amplifier and the aperture instead of be ...

Clouds play leading role in the Earth's global energy and solar radiation balance. Improving cloud models requires information on the cloud microphysical properties, such as particle size distribution and concentration, cloud composition (droplets, ice particles) and also information on ice crystal shapes (habits). New lightweight and low power instruments for characterization of mixed-phase cloud ...
