Assignee: AURA INTELLIGENT SYSTEMS, INC.
Field: Measurement (Instruments)
Classification: CPC H  G | IPC G  H

Claim 0:
1. An advanced radio apparatus, comprising:
a set of antennas;
an analog circuit;
a digital circuit;
a medium access control (MAC) controller;
a processor operably connected to the set of antennas, the analog circuit, the digital circuit, and the MAC controller, the processor configured to:
decompose wideband waveform signals into a time-frequency waveform based on a sequence of sub-band signals;
generate a time-frequency radar waveform based on the decomposed wideband waveform signals; and
map, based on the time-frequency radar waveform, a constant amplitude zero auto-correlation (CAZAC) sequence into orthogonal frequency division multiplexing (OFDM) sub-carriers to generate a first radar signal; and

a transceiver operably connected to the processor, the transceiver configured to:
transmit, to a target object via a transmit antenna of the set of antennas, the first radar signal; and
receive, via a receive antenna of the set of antennas, a second signal that is reflected or backscattered from the target object.
