Far-Field to Near-Field Test Comparison Results for Evaluation of Test Article

摘要

Over the past six years the Navy has developed a portable measurement capability. As part of the validation of this tool a comparison test was developed to understand the issues involving testing complex targets in a near-field cluttered environment. The test was designed to evaluate not only the effects of near-field curvature, but how clutter from ceiling and walls have an effect on the accuracy of the measurement.rnThe test measured all test objects in the far-field as a baseline, then repeated the same measurements at five different near-field configurations. The results of the test will be shown on a simple 15 ft. pole target, along with the metrics for evaluation of the results.
