The Effects of Pseudo-Color on the Apparent Displayed Dynamic Range of Radar Imagery.

摘要

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 pseudo-color encoding of radar/display transfer functions by which the information contained within the large SAR dynamic range could be presented to human observers. The codes developed were evaluated by measuring operator performance improvement compared with a monochromatic code for a strategic, tactical, and reconnaissance mission task. The pseudo-color codes offered no improvement in the strategic mission task; however, the tests indicated that the developed pseudo-color codes may improve operator performance in the tactical and reconnaissance tasks. These codes appear particularly promising when used with radar resolutions where the target returns are clearly above the clutter background. (Author)
