ABSTRACT:
Apparatus is provided for compressing unfocused synthetic aperture radar (SAR) phase history pixel data by coupling the complex inphase phase history data output from the SAR to a first converter/compressor which produces compressed scalar log amplitude data and scalar phase pixel data. The output from the first converter/compressor is applied to a series to parallel converting means for converting plural scaler pixel data into vector data representative of a plurality of pixels. The output of the series to parallel conversion means is coupled to a second converter/compressor for converting the plural scalar pixel data into compressed encoded data representative of a plurality of pixels of unfocused SAR phase history data which is transmitted as compressed unfocused phase history data.
