Abstract

With radar emerging as a new technology for the safety application space, safety standards were made in order to define what it takes for a radar-based safety system to be considered safe. The newly created IEC TS 61496-5:2023 has set performance requirements that a radar protective device within a safety system must meet in order to be certifiably safe. The requirements given are in context to the detection of an adult human being present in an industrial manufacturing environment that contains areas that must be monitored for safety. Functional tests were created that obstruct the sensor in different ways while attempting to detect an actual person or a corner reflector rated to the 99th percentile of a human being. This document covers what functional tests are listed within IEC TS 61496-5:2023 in order to verify radar performance for an adult human, the many terms their definitions used throughout the standard, and how the IWR6843 and IWR6843AOP mmWave Radar sensors passes the requirements defined.
