The adaptive single user receiver invented at AF LAB has been shown to suppress multiuser and certain forms of narrow-band interference in adecision directed mode during the entire transmission, without requiring knowledge of other users spreading codes, timing or phase information in direct-sequence proposal, we investigate the use of our single user receiver for secure communications as required ...

Cylindrical non-axisymmetric optical components are becoming increasingly important to both commercial and military applications. Current manufacturing methods are very labor intensive and require dedicated tooling. This resulted in a major shift of manufacturing base to off shore manufacturers. Recent advances in Deterministics Microgrinding of spherical surfaces demonstrate that specular surf ...

This Phase I effort will ascertain the practical aspects of assemblin g a cost-effective, reliable, compact optical security system using phase-encryption of identification data in conjunction with phase- and/or amplitude-encoded biometric signatures and develop a preliminary design and demonstration plan for Phase II. For this Phase I effort, we will use fingerprints as the primary biometric iden ...

IDSS in partnership with Tufts University Human Factors Engineering Program, a leader in Engineering Phycology, proposes to study CT screening system operator burden and reduce image review time by reviewing and making improvements to the GUI and the current man-machine interaction and perform limited prototyping of potential improvement to the operator interface and toolset.

Gun-launched applications currently expose inertial measurement units (IMUs) to harsh acceleration, shock, and vibration environments. Furthermore, as they become smarter, they present tighter constraints on size, weight, power, and cost (SWaP-C), while still requiring high levels of performance. New accelerometer technology must reduce SWaP-C while operating through high-g acceleration environmen ...

In implementing an electro-optic (EO) seeker, the selection of a waveband or wavebands is the major decision for the system design. The visible and near-infrared wavebands work well in the daytime when the atmosphere is clear, but passive imaging systems in these bands are not useful at night, and they are susceptible to scattering in fog, smoke, and dusty environments. The mid-wave infrared (MWIR ...

Mission times for high velocity projectiles (HVP) are very short and detection and discrimination of targets must happen quickly and decisively. One way to achieve this is through the enhanced contrast resulting from polarized sensing, which tends to highlight manmade objects and suppress natural background clutter. Thermal polarimetric sensing in a small package has been demonstrated already but ...

The capability to reliably and remotely detect and track tactical surface targets in a high-velocity projectile after launch is a critical need. The discrimination of man-made objects can be assisted by the detector technology, with options including two-color detectors and polarimetric filtering in the thermal infrared bands. The level of complexity in the focal plane array affects its survivabil ...

Black River Systems is developing real-time fire control tracking and threat prediction capabilities for land and sea - based missile defense. Our nation faces a rapidly evolving set of missile threats that exhibit extreme velocities, high dynamic motion and difficult to predict maneuverability. There are many different trajectories and many types of threats: subsonic, supersonic; sea-skimming, la ...

Deep-learning Ephemeral-Pad Encryption Neural Networks (DEPENN) software applies one-time pad and quantized neural network technologies to provide efficient, moving-target encryption of all data associated with neural network operations. DEPENN overcomes the significant computational burden and technical challenges of fully homomorphically encrypted neural network operation while providing compara ...
