【国外标准】 IEEE Standard for Measuring the Imaging Performance of Active Millimeter-Wave Systems for Security Screening of Humans

This standard applies to security screening systems that utilize millimeter wave (MMW) radiation to actively inspect persons who are not inside vehicles, containers, or enclosures. The standard is applicable to systems used to detect concealed objects carried on the body of the individual being screened at a security checkpoint. This standard addresses monostatic, bistatic, or multistatic MMW systems. Walk-though systems can be tested using the standard. This document focuses on the imagery… read more that is presented to an Automated Threat Recognition (ATR) algorithm, not the imagery presented to a human screener. This standard applies to systems that are primarily imaging but that also may have complementary functionality such as materials discrimination. This standard does not address how to test these complementary functions. The standard describes the tools, objectively-analyzed test methods, and image quality metrics for characterizing the imaging performance of the system but not for its operational performance. For the purposes of this standard, the test objects herein are appropriately applied to characterize systems that use radiation from 3 GHz to 150 GHz (100 mm to 2 mm wavelength). The standard is limited to tests related to image quality or functional factors that affect image quality. It does not, for example, include tests or requirements for electrical safety, or electromagnetic interference or immunity. This standard does not specify minimum or baseline performance requirements (pass-fail thresholds). read less
