Clutter-Limited Electric and Magnetic Field Sensor with Self Orientation and Calibration

The goal of Phase II is to add orientation, self calibration, and digital data link to a proof of concept six channel electromagnetic (EM) sensor (3 B-field) to produce a prototype EM Vector Sensor Node (EM-VSN). The node will communicate with a hostcomputer via a low cost 4-wired Ethernet link. Software will be developed to allow automatic projection of the measured fields into any three axis reference frame, and for user-transparent self calibration to correct for changes in the sensor response dueto its environment. The system will incorporate methods to reduce vibration noise and, if possible, accommodate the motion from a moving platform. The system will be tested outdoor to demonstrate all capabilities, and will undergo preliminary tests inthree potential military sensing applications.
