DEF

polarization of a propagating wave is determined by the locus or path described by the electric field vector with respect to time

OBS

Polarization is a term that often arises in the literature and when considering radio frequency communication and RFID. If we ascribe an x, y, z co-ordinate system to a propagating wave as illustrated below, with the direction of propagation being in the z direction, the electric field vector E will be in the x, y plane. If E remains in the same orientation with respect to time, so that its locus describes a straight line, the wave is said to be linearly polarized. However, if the locus describes a circular motion with respect to time the wave is said to be circularly polarized. Where the locus describes an elliptical path, the wave is said to be elliptically polarized.

OBS

Circular polarization is often used in communication systems since the orientation of the transmitting and receiving antenna is less important than it is with linearly polarized waves. The magnetic vector, H, always remains perpendicular to the E vector. Using an IEEE convention, a clockwise circular rotating wavefront approaching a receiver is defined as being left-hand circular (LHC) polarized. The power in the wavefront is expressed in the form of the Poynting vector, P: P = (E x H) = E x H sin ..., where ... is the phase angle between E and H.

Imagery Exploitation System (IES). Modernized Imagery Exploitation System (MIES). MIES is a Corps and EAC tactical imagery exploitation system capable of receiving, processing, and disseminating national and theater imagery. The MIES provides first phase imagery exploitation for the Indications and Warnings (I&W) missions of Army users. The system provides IMINT reports and Secondary Imagery Dissemination (SID) through an extensive communications section. It travels with its own satellite communications (SATCOM) system that provides the relayed national imagery through the Defense Dissemination System (DDS).

CONT

The imagery Exploitation System/Balanced Technology Initiative(IES/BTI) is a first phase near-real time image exploitation system to support Army Corps intelligence and electronic warfare(IEW) situation development, target development and target acquisition. IES/BTI exploits synthetic aperture radar(SAR) and infrared(IR) imagery and annotates the presence and type(artillery, armor, etc) of military units(company size and above). IES/BTI employs a hierarchical reasoning paradigm, using Bayesian inference for hypotheses management and belief propagation to solve the complex force/terrain/military situation and formation.

Forest biometrician.... Participate in a team oriented research project assessing the carbon dynamics of forest ecosystems at country to regional scales, including the effects of changes in land cover, land use, and land management. The current research focus is to quantify the carbon flux(either sink or source) from changes in land use and land cover for several major boreal, temperate, and tropical countries. The primary duties will be : 1) estimate errors and their propagation for all components of national-scale terrestrial C budgets; 2) design sampling strategies for data collection from field sites to remote sensing scenes; 3) perform statistical analysis of inventory data for estimating status and trend of forest biomass-carbon densities; 4) design a data management system, including quality control procedures, for keeping track of estimates of means and associated errors of carbon budget components that vary over time and space....
