Complex early and late neuropathies resulting from direct and conductive electrical patterns of injury are disabling and extremely challenging to manage. We report a patient who suffered acute onset of right-hand weakness and decreased sensation following a radar equipment-related electrical injury. He received a carpal and Guyon tunnel release, regaining sensation and strength to his right han...

Radar automatic target recognition (RATR) technology is fundamental but complicated system engineering that combines sensor, target, environment, and signal processing technology, etc. It plays a significant role in improving the level capabilities of military civilian automation. Although RATR has been successfully applied some aspects, complete theoretical not established. At present, deep le...

A novel range-instantaneous-Doppler (RID) algorithm of inverse synthetic aperture radar (ISAR) imaging based on adaptive Doppler spectrum extraction is proposed in this paper. Regarding maneuvering targets, such as military aircraft, the ISAR image is blurred on cross-range domain when the range-Doppler (RD) algorithm is applied. The RID imaging method is often used to resolve the Doppler ambig...

A fuzzy logic based resource manager (RM) that will allocate resources distributed across many platforms is under development. The platforms will consist of ships, aircraft, etc. The resources will be various sensors: ESM, RADAR, IFF, and communications. The RM will allow codification of military expertise in a simple mathematical formalism known as the fuzzy decision tree. The fuzzy decision t...

Ultra wide bandwidth (UWB) signals are commonly defined as signals that have a large relative bandwidth (bandwidth divided by the carrier frequency) or a large absolute bandwidth .On the other hand, generating, receiving, and processing UWB signals poses significant challenges that require new research in signal generation, transmission, propagation, processing, and system engineering. In the p...

The solution of Maxwell's equations for irregular 3D structures have been used traditionally for oil-exploration, detection of radar-cross-section of military vehicles, antenna analysis, bio-medical applications and more recently in predicting electrical performance of RF and high speed circuits and systems. Since 1950s applied mathematics, physics, and engineering communities have refined the ...

Motion parameter estimation of a ground moving target is an important issue in synthetic aperture radar ground moving target indication (SAR-GMTI) which has significant applications for civilian and military. The SAR image of a moving target may be displaced and defocused due to the radial and along-track velocity components, respectively. The sharpness cost function presents a measure of the d...

Intensive research and development during the Second World War had resulted in new technologies uch as radar, the proximity fuse, and the atomic bomb, all of which contributed to the Allied victory. The Cold War marked a new era in government funding for research and development, however, as new geopolitical pressures convinced military and civilian policymakers to maintain R&D expenditures ata...

Ultra wide band (UWB) radar hologmphy is a unique technique developed at PNNL for the U. S. Army to obtain nearfield "3-D" images and scattering characteristics of full-size vehicles in the field and at productwn line facilities. The extremely high-resolution imaging capability of this technique maps a vehicle's scattering areas and idenhfies the "hot spots" which dominate the far-field signatu...
