Increasing performance of a receive pipeline of a radar with memory optimization

A radar sensing system comprising:

• a transmit pipeline comprising a plurality of transmitters configured to transmit radio signals;
• a receive pipeline comprising a plurality of receivers configured to receive radio signals that include the transmitted radio signals transmitted by the transmitters and reflected from objects in an environment;
• a sparsifier processor;
• and
• a memory;
• wherein the receive pipeline is configured to correlate the received radio signals with a plurality of time-delayed replicas of the transmitted radio signals to produce first samples stored in the memory, wherein the first samples are arranged in the memory as a first data structure that comprises an array of ranges of different objects in the environment as measured by different receivers;
• wherein the receive pipeline is configured to process the first data structure to estimate Doppler/velocity of objects in the environment for given ranges and given receivers to produce a second data structure that comprises an array of Doppler/velocity estimates of the different objects as defined by their corresponding given ranges for the given receivers from the first data structure;
• wherein the receive pipeline is configured to output the second data structure to the sparsifier processor;
• and
• wherein the sparsifier processor is configured to analyze the second data structure to compute a compressed version of the second data structure that comprises selected portions of data contained in the second data structure, and wherein the compressed version of the second data structure is stored in the memory for further processing.
