A reception unit receives a reception signal resulting from the transmission signal being reflected by a target and outputs a beat signal based on the transmission signal and the reception signal. A control unit determines whether or not three or more targets that have the same relative speed are present at the same orientation among a plurality of targets extracted from a plurality of peak frequencies in each of the rising portion and the falling portion of the beat signal, and when determined that three or more targets are present, gives notification that oscillation has occurred in a power supply bias circuit that supplies power supply voltage to the transmission unit or the reception unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"FMCW radar device","description":"In a FMCW radar device, a transmission unit transmits a transmission signal that has a rising portion in which the frequency successively increases and a falling portion in which the frequency success","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9797991","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.
