A target angle estimation technique making effective use of the spatial degrees of freedom of an adaptive array radar system has been developed by ASI and demonstrated to yield unbiased and efficient angle estimates in near-main beam jammer environments. The program objective of progressing towards a feasibility demonstration includes optimizing system designs including the detection and post-dete ...

We propose to develop sensor technology capable of high resolution imaging of electromagnetic radiation in the energy spectrum spanning the ultraviolet to x-rays. Phase I calls for the fabrication of small scale image sensors. These sensors are fabricated from CMOS arrays, coated with selenium and then a conductive electrode. These sensors will undergo testing and performance evaluation for both x ...

Functional gradient materials (FGMs) have a microstructurally graded transition in composition (e.g. zirconia to a nickel based superalloy). The graded transition eliminates problems associated with a discrete interface such as poor mechanical strength and transport losses. They are being actively pursued by the engineering community, particularly in Japan, as a means of taking advantage of two di ...

The proposed program is to develop the use of aqueous biopolymers for the solid freeform fabrication of ceramic components. It will be a collaborative effort between ACR and Battelle PNL. PNL has expertise in colloidal ceramic processing and experience on utilizing biopolymers in ceramic slurries. ACR has already developed extensive software and hardware capability for solid freeform fabricatio ...

BESOI fabrication techniques will be evaluated to select an optimum approach for manufacturing ultrathin silicon films on 150- and 200-mm diameter wafers. A supplier of such BESOI material will be identified. The baseline will be the SiGe etch stop and strain-sensitive etch method which ARACOR has already demonstrated to be capable of producing defect-free, undoped films that are as thin as 1000 a ...

THE CURRENT FIVE-POINT MILITARY AVIATION RESTRAINT SYSTEM (FOR NON-EJECTION CREW SEATS) WHEN PROPERLY USED (I.E., TIGHTLY ADJUSTED), CAN PROVIDE GOOD OCCUPANT CRASH PROTECTION. THE RESTRAINT SYSTEMS ALSO INCLUDE AN INERTIAL REEL ON THE SEAT BACK WHICH IS DESIGNED TO LOCK THE SHOULD STRAPS AT THE ONSET OF A CRASH, IN THE SAME MANNER THAT THE COMMON AUTOMOBILE SEAT BELT INERTIAL REEL LOCKS WHEN JERK ...

The Discrete Wavelet Transform (DWT) is a Time-Frequency Distribution (TFD) which offers the potential to efficiently characterize both transient and global intrapulse signal features in a highly compressed format. The overall objective of this three phase effort is to develop Wavelet analysis as a new approach to modulation on pulse (MOP) processing in support of electronic warfare (EW) systems i ...
