Laboratory investigations have suggested that acoustically or vibrationally inducing motion in buried targets can aid in improving target detectability through a characteristic response related to differential target motion. This gain is realized by adding an additional degree of freedom, modulation due to motion in the GPR return signal, to use as a discriminating feature. The AKELA team is propo ...

Additive manufacturing (AM) technologies covering a broad range of technologies and processes have been under continuous and accelerating development since the 80s. While there are still fundamental hurdles such as low production rates and small sizes, AM holds tremendous promise in terms of revolutionizing manufacturing. Recent trends include direct-printing and incorporating sensors and electr ...

Computer wargames and combat simulation software has reached a very high level of comprehensiveness and sophistication in terms of modeling fidelity and accurate results. The recently released simulation titled Point of Attack-2, in particular, affords users a very powerful combat simulation package in a desktop PC environment. At the same time, however, the increased complexity of the system ma ...

An investigation of a broadband analog optical modulator linearization scheme is proposed. The scheme is based on the combination of multiple semiconductor modulator devices, driven from a common electrical input. The linearization is accomplished in the optical domain, making the approach suitable for wideband microwave applications that have frustrated previous attempts at electrical pre-distort ...

Filamentation of ultra-short laser pulse propagation in non-linear media offers significant potentials allowing to address numerous problems in military and commercial sectors. However, practical implementation of this requires an ability to control the USLP at its propagation through inhomogeneous media, like turbulent atmosphere. On the basis of our approach for combating turbulence effects on p ...

Ultra-short pulse lasers have advantages over continuous-wave lasers for directed-energy applications due to the high peak powers that can be reached. Directed-energy weapons are profoundly limited by the aberrations caused by atmospheric turbulence and current adaptive optics can correct for these aberrations only when the propagation medium is reciprocal. Unfortunately, nonlinear effects in the ...

Energy-on-target is maximized in optics and ocean acoustics by transmitting a time-reversed (spectral phase conjugated) version of received data at each array element or subarray. This process uses an unknown propagation channel as its own space-time matched filter to implement a RAKE receiver at the target location. (A RAKE receiver passes data through a filter that is matched to the channel im ...

The Department of the Navy has a need for the development of an additive manufacturing (AM) process for key vacuum electronic device components to meet on-demand, flexible, and affordable manufacturing requirements. The developed manufacturing method has a potential to reduce cost of vacuum electronics by as much as 70% as well as simplify and hence expedite production process of these devices by ...

This STTR project will develop and validate a robust, scalable computational capability for the simulation of weapon-target interactions of interest to the Army.
