A mobile satellite communications link operating from vehicles on-the-move would provide significant benefits to the Marine Corps in the battlefield environment. The antenna should be capable of simultaneous and rapid tracking of two satellites while the vehicle is in motion over rough terrain, as well as providing ultra-wide bandwidth (C-band through Ku-band), medium to high gain, low profile, ru ...

Alphatech will develop & demo multirsolution statistical methods for the fusion of terrain elevation from existing 3-D terrain models and new elevation data. This fusion will produce new estimates of terrain elevation with accuracies, robustness, and update ratesprviously unachievable.

An important problem in the analysis of ATR systems is quantifying the growth of algorithm requirements, such as storage and processing cost, as the input problem l situation in classical complexity analysis, where the notion of input size is well-defined, there does not currenlty exist a clear notion of input size for the ATR problem. In this effort ...

X-ray imaging is an important technique which is used in variety of applications such as general radiology in medicine, astronomical observations, non-destructive testing, X-ray diffraction for materials studies and others. The ability of X-rays to penetrate deep in to matter allows investigation of interior components with possibility of real-time dynamic studies. However, while significant advan ...

Silicon avalanche photodiodes are among the most sensitive optical detectors available today. It 11as been shown that large area APDs are potentially an excellent alternative to photomultiplier tubes (PMTs) in applications such as LIDAR, nuclear medicine, physics research and nuclear radiation measurement instrumentation. They can offer improved performance based on their compact size, solid state ...

The objective of this research is to define and validate an Avionics Information Fusion System (AIFS) which optimally combines onboard and offboard data. We propose an architecture containing an offboard data processor to extract data relevant to the mission, and a set of fusion modules for recursively associating sensor reports, tracking targets, and classifying targets. These modul ...

recent advances in sensor technology have enabled collection of vast quantities of battlefield information. Warfighters will soon gain global access to this huge volume of information. Rather than construct separate redundant, and inconsistent situation estimates, a Dynamic Database can reduce the data to a comprehensive, self-consistent representation of the environment. This proposal explores ...

We propose a two-pronged program for developing Air Force capability in SAR/FLIR sensor fusion for automatic target recognition (ATR). In the first component of this program, we will design, implement and demonstrate a sequence of increasingly sophisticated SAR/FLIR fusion systems, each tuned to maximize the joint benefit of these complementary sensing modes for a different level of algorithm com ...

We propose a comprehensive program for analyzing the performance of multi-source georegistration systems needed to support theater-wide sharing and fusing of information for Air Force platforms and missions. We have designed our program to build upon the work done under AFRL's Theater-wide Reference Information Management (TRIM) program. While TRIM has analyzed the accuracy of multi-source fusio ...
