  8. 8. 01 INTRODUCTIONSAR IMAGES: AVDVANTAGES AND DRAWBACKS Advantages: you program, you get it! All Weather + Day and Night Drawbacks: it is hard to use! (radically distinct from optical) Need of specialised training Specialised SW SAR Imagery Analysis for Defence and Security SAR Images present distinct spectral and radiometric characteristics from optical data, so a different analysis is required. We see different things! Cannot replace optical imagery photointerpretation performance, but it can be the only choice! Caveat: Wrong expectations, prejudices and lack of training or processing infrastructure can make optical analysts reluctant to use SAR imagery and yield project failure. A new mindset is needed 8
  9. 9. 01 INTRODUCTIONSAR IMAGES: METHODOLOGY WHERE? HOW? PRODUCTS In areas where A complement to One image is used optical data fails to optical imagery. for target detection, deliver, permanent recognition, and cloud cover areas or Best performance identification. SAR Imagery Analysis for Defence and Security during the night . when the area is previously known Pair of images is Crisis situations, used for change and we focus on where more frequent detection. Can use changes. acquisitions are radar phase! needed. Only in exceptional cases, when optical Set of images are data is not available, used for temporal the analysis of an analysis of changes. area can be based only on SAR images. 9

  35. 35. 02 Methodology for Defence & Security Applications SUPER RESOLUTION IMAGES ADVANTAGES Advantages: Superresolution images ease and improve the imagery analysis wrt Speckle reduction without spatial resolution loss. Better border definition. Volumetric features and textures: forest, trees,... Small features. SAR Imagery Analysis for Defence and Security Drawbacks: Higher cost: at least 3-4 images are needed to obtain an acceptable SSI image. Choice of the dates is very important for a proper interpretation of the changes. 35
