Evaluating performance of microwave-based handheld mine detection sensors has until recently been limited to using tethered test carts instrumented with a network analyzer and computer controller. The Army's Night Vision and Electronic Sensors Directorate's (NVESD) Mine Detection Division has completed the development of a versatile portable data acquisition system (DAS) enabling researchers to simulate handheld mine detection systems and to evaluate mine detection antennas from 500 MHz to 2000 MHz. The data that is collected by the DAS is in the form of the complex S21 and S11 scattering parameters and includes sensor head position. System software is in a data collection instrument useful for evaluating the performance of detection algorithms and antennas, or as a fully operational handheld mine detector brassboard. Described in this paper are the technologies comprising the DAS, a detailed system description, and results from an experimental effort using the separated aperture antenna mine detection technique to measure the performance of the DAS in an outdoor environment.
