Abstract:

Synthetic aperture radar SAR has a dynamic range much greater than displays used to present the radar ground map video to human observers. This study program was undertaken to explore techniques by which the information contained within the large SAR dynamic range could be presented to human observers. In the pursuit of this goal, monochromatic adaptive gray shade transform, pseudocolor encoding, and feature analytic techniques were examined. Although some of the monochromatic and pseudocolor techniques resulted in improved quality of SAR video images, the improvement was judged insufficient to justify implementation of such techniques in real- or near-real-time SAR systems. Feature analytic techniques used as automatic search, detection, and cueing aids to human observers showed considerable promise, and further work was recommended in this area. Author
