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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sub-band and multi-band coded OFDM for high-resolution radar","description":"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 cir","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11936477","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
