Research in Data Compression for Microwave Imagery and Its Effect Upon Image Quality

摘要

In microwave imaging, aperture data are digitized, while system performance is determined by the quality of the image, which is usually a Fourier Transform of the aperture data. This research develops a methodology for finding a quantizer in the aperture domain which optimizes an image plane quality criterion. For amplitude-phase quantization of complex data, a novel optimality criterion is posed which leads to a new and simpler optimal quantizer design. Keywords: Data compression, Microwave imagery, Image quality, and Optical quantizer design. (RH)
