摘 要：SERDP project MR-1712 entitled ?Portable Electromagnetic Induction Sensor with Integrated Positioning? is slightly more than halfway complete. The transmitter (Tx) and receiver (Rx) assemblies are designed and fabricated. The data acquisition (DAQ) electronics consists of the National Instruments (NI) cRIO platform which is much lighter and more efficient that prior DAQ platforms. Software to control the cRIO DAQ process has been written in NI?s LabVIEW. This software has been used to successfully acquire initial data. Inversion of the data acquired during these initial tests has yielded satisfactory polarizabilities of a spherical target. In addition, precise positioning of the Rx assembly has been achieved via position inversion algorithms based solely on the data acquired from the receivers during the on-time of the primary field. Major tasks still to complete include redesigning and integrating new transmitter and filter board control circuitry as well as final cable construction and integration. The LabVIEW programs must also be matured to become more user friendly. A more extensive prove-out is scheduled for May,2012 after which will follow an extensive data analysis. Finally, we intend to go to Aberdeen Proving Ground in the Fall of 2012 to perform a field test of Pedemis, test its protocols, and evaluate its performance.
