Radar-guided weapons can be confounded by a number of factors, including clutter, jamming, target glint, and engine modulation. Missile/target encounter simulations, if they are to test a homing systems weak points, must incorporate these effects. We propose to investigate the electromagnetic (EM) modeling requirements for a complete radar-guided weapon system simulator. Specifically, in the Pha ...

The development of new innovative multi-spectral target and clutter modeling techniques has a wide range of commercial and military surveillance and intelligence, electronic warfare, and mission planning applications. High fidelity multi-spectral prediction codes such as Xpatch, Xpatch_ES, PRISM and SPIRITS provide significant fidelity improvements over existing modeling and simulation tools. ...

DoD's real-time mission planning, electronic warfare and other modeling and simulation systems generally utilize manual entry of RCS values for the generation for radar simulator displays and system performance analysis. Given the large amounts of measured data available at NAWC/WD,Pt. Mugu, as well as from other DoD and industry test facilties, it would be effective to automate the full utiliz ...

The use of synthetic data for the generation of target signature templates is a vital element of current and future automatic target recognition systems. [1] [2] Although current synthetic signatures closely match their measured counterparts, they suffer from two shortcomings: 1) susceptibility to model error and 2) poor representation of signature variance. The current model validation relie ...

DT Optics proposes to develop and produce large three-dimensional photonic crystals for a new class of lasers. Lasers already have had extensive and important commercial and military applications. The key to produce more powerful and more efficient lasers lies in production of more efficient optical cavity with optical amplifying medium embedded. The hope is in photonic crystals. This proj ...

A 300 Kw permanent magnet brushless dc motor with axial gap configuration to fit within 23 inch diameter by 10 inch long package is proposed for tracked vehicle applications. The stator constructed using novel concepts results in under 24 p.s.il, 4.4 gallons/min. oil flow to keep the maximum winding temperature under 200 deg C. The motor voltage is limited to 500 Vdc, and the efficiency including ...

The fabrication of large format, long wavelength (LWIR) mercury cadmium telluride based focal plane arrays (FPAs) is highly desirable for Air Force applications such as satellite power and array cooling reduction along with higher resolution. However, the development of large FPAs has been seriously impeded by the limited size of commercially available bulk Cd{sub 1-x}Zn{sub x}Te substrates. In ...

Large planar arrays which consist of several hundred to several thousand antennas provide narrow, high gain pencil beams. Electronic beam steering for terminal guidance radar can be achiev ed using frequency scanning, beam switching, time delay or phase delay. Electronics steering allows beam manipulations in tens of nanoseconds using compact, mechanically rigid structures. Due to the increase in ...

We propose to develop a family of star and tree coupler systems that are modular. Each coupler system will include three modules: a fiber/cable input module, a routing module and a fiber/cable output module. The input and output modules will secure the strength means in the input and output fiber ribbon cables and each will use an MFP to position and support the individual optical fibers. ...

Gateway Materials Technology and BIRL-Northwestern University propose to develop a deposition process for oxide coatings on ceramic fibers based on an aqueous chemistry route. Hetreogeneous deposition chemistry (HDC) utilizes precise control of concentration, solubility, and surface area to precipitate particles and costings directly on selected surfaces, based on knowledge of nucleation and grow ...
