Patent ID: 11936477

Abstract:
An advanced radio apparatus includes a set of antennas; analog circuit; digital circuit; medium access control (MAC) controller; and processor operably connected to the set of antennas, the analog circuit, the digital circuit, and the MAC controller. The processor is 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; 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. A transceiver is connected to the processor and 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.
