Synthetic aperture radar data compression and transmission

摘要

The present disclosure generally relates to techniques for processing complex-valued array data representing an image. The techniques may include obtaining an electronic representation of an array of complex numbers representing an image, converting the array of complex numbers to an array of scaled coordinate pair values in a magnitude-phase plane, replacing each coordinate pair value with data representing a respective nearest node in a quantized magnitude-phase plane, such that an array of scaled quantized coordinate value pairs is produced, arranging into a sequence of bit values ordered according to decreasing bit significance, from most-significant bit values to least-significant bit values, the scaled quantized coordinate value pairs, and transmitting the sequence of bit values to a receiver, such that the receiver rearranges and rescales the sequence of bit values and obtains the image represented by the array of complex numbers.
