Synthetic aperture radar data compression and transmission

A method of receiving, decompressing, and processing complex-valued array data representing an image, the method comprising:

• receiving via a network interface communicatively coupled to a transceiver, an electronic representation of a sequence of bit values representing an image, wherein the sequence of bit values are ordered according to decreasing bit significance, from most-significant bit values to least-significant bit values;
• rearranging, by an electronic processor, the sequence of bit values into an array of scaled quantized coordinate value pairs;
• converting, by an electronic processor, the array of scaled quantized coordinate value pairs to an array of complex numbers;
• and
• displaying, on a computer monitor, an image represented by the array of complex numbers.

A system for obtaining, preparing, and transmitting complex-valued array data representing an image, the system comprising:

• a network interface comprising an electronic processor, communicatively coupled to a transceiver, and configured to obtain an electronic representation of an array of complex numbers, wherein the array of complex numbers represents an image;
• and
• at least one electronic processor configured to:
• convert the array of complex numbers to an array of scaled coordinate pair values in a magnitude-phase plane;
• replace each coordinate pair value with data representing a respective nearest node in a quantized magnitude-phase plane, whereby an array of scaled quantized coordinate value pairs is produced;
• and
• arrange 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;
• wherein the transceiver is configured to transmit the sequence of bit values to a receiver, whereby the receiver rearranges and rescales the sequence of bit values and obtains the image represented by the array of complex numbers.
