Visual Interpretation of SAR Images. (Visuele Interpretatie van SAR Beelden)
Abstract
SAR images are difficult to interpret for non-trained persons because these images are fundamentally different from optical images. The goal of the project was to find out how SAR images should be displayed in order to facilitate the interpretation of these images for terrain interpretation and target acquisition. This project was a combined effort by TNO-FEL and TNO-TM. In the project polarimetric PHARUS images and high resolution RAMSES images were used for two experiments where people were tested for their ability to find targets and to interpret the terrain. The PHARUS data were displayed in grey tones and false colours. The false colours were obtained by displaying two or more polarisation channels in the colour channels of the screen. In this way a single, two and three channel presentation was obtained. The experiments showed that the two-channel presentation is more effective than the single channel presentation for visual interpretation of the images. The three-channel presentation did not improve the scores of the experiments significantly. This result is important when a SAR is used on a UAV, since it is clearly easier to mount a two-channel than a three-channel SAR on a UAV.
