N2 - Results are presented of planar near-field antenna measurements of a 2x1m slotted waveguide antenna panel, measured at Physisch Lab TNO, before and after thermal cycling at Estec. Results of the complete 10x1 meter Synthetic Aperture Radar antenna are shown, inclusive a transformation back to the antenna aperture. The latter approach is useful for (active) phased array antennas to investigate deviations at local level in the antenna aperture De terug transformatie naar de 10x1 meter antenne apertuur is te vinden in Fig.23 van een JINA paper: "Antennas for Remote Sensing", JINA conference 1990, C.G.M. van 't Klooster, N.E. Jensen, 14 pages, invited paper.
