Claim 0:
1. A method, comprising:
storing radar data in a memory, the radar data being stored in a data cube having bins distributed in positions described by indices along dimensions including a slow-time dimension, a fast-time dimension, and a channel dimension;
dividing the data cube along a first dimension into one or more zones;
for each zone,
selecting a number of data matrices, each data matrix comprising data vectors having bins that share an index value in a second dimension, wherein the number is based on a compression factor, further wherein the number of data matrices selected for a first zone is different from the number of data matrices selected for a second zone;
forming sets of data matrices containing the number of data matrices;
for each set of data matrices, for each data matrix, applying a signal processing coding scheme to data vectors in the data matrix to generate a coded data matrix, wherein a signal processing coding scheme for data vectors in a data matrix is the same and a signal processing coding scheme for different data matrices is different; and
combining the coded data matrices in the set in the second dimension to generate a compressed data matrix for the zone; and

storing the compressed data matrices for the one or more zones in a memory, wherein the compressed data matrices correspond to a compressed data cube.
