4.2 Position Accuracy

IEC 61496-5:5.2.10

Although the most important aspect of a safety sensor is knowing if the safety zone is occupied, knowing where the occupant is with respect to the RPD is important as well. With the fundamentals of radar, there is a degradation in range and angle accuracy at maximum FOV as well as at and before the minimum detection distance of the RPD under test. The standard defines limited positional accuracy in Section 3.508 and Section 4.1.6 as the areas where the degradation mentioned above occurs.
