Fractalet radar processing

A non-transitory computer-readable medium having stored thereon instructions that, when executed by one or more processors, are configurable to cause the one or more processors to:

• receive a reference fractalet waveform from a radio detection and ranging (RADAR) frequency transmission architecture, wherein the fractalet waveform includes self-similar waveforms comprising a first plurality of lower frequency bands and a second plurality of higher frequency bands;
• decode a reflected fractalet waveform received via one or more antennae;
• compare a waveform profile of chirplet transforms of signals in the first plurality of lower frequency bands within the reflected fractalet waveform to the reference fractalet waveform;
• determine one or more time spans corresponding to the subset of lower frequency bands;
• extract signals from the second plurality of higher frequency bands from the reflected fractalet waveform;
• determine chirplet transforms for the extracted signals from the second plurality of higher frequency bands in the reflected fractalet waveform for the one or more determined time spans;
• and
• calculate spatial frequency components along an azimuth direction and along an elevation direction for one or more targets based on the chirplet transforms for the extracted signals from the second plurality of higher frequency bands.

A system comprising:

• a memory system;
• and
• one or more hardware processors coupled with the memory system, the one or more processors to:
