Interlaboratory comparisons in radar cross section measurement assurance

摘要

The National Institute of Standards and Technology (NIST) is coordinating a radar cross section (RCS)interlaboratory comparison study using a family of s tandard cylinders developed at Wright Laboratores. As an important component of measurement assurance and of the proposed RCS certification program, interlaboratory comparisons can be used to establish repeatability (within specified uncertainty limits) of RCS measurements within and between measurement ranges. We discuss the global importnace of intercomparisons in standards metrology, examine recently conducted comparision studies at NIST, and give a status report on the first national RCS intercomparison study. We also consider future directions.
