Dependence of False Positive [top row] and False Negative [bottom row] Rates on the number of measurements M, with [left] or without [right] phase information. We contrast using M different random DMA configurations [blue] with M repeated measurements of a fixed random DMA configuration [red] or a simple open ended waveguide probe (OEWG) [green]. The dash-dotted lines are obtained by using the knowledge that in a given interval motion does not occur or stop only at a single moment in time, cf. main text.
