Abstract

Operational interpretation of SAR imagery is degraded by display/processing limitations. For example, the inability to maintain optimum focus over an entire image often results in severe impulse response degradation. Conventional hardcopy film recording can handle only a portion of the available SAR dynamic range; the benefits of a wide dynamic range are lost. Holographic viewers offer a means of overcoming these problems as well as offering potential benefits in other areas, such as sidelobe weighting and artifact removal. Most important, these operations can be performed interactively by the interpreter according to his requirements. The benefits of holographic viewers are unique, not being shared by other display devices -- film and CRT displays. The capabilities of current holographic viewers are discussed. Comparisons in terms of cost and utility are made with other display media. Recommendations for further development are presented.
