In a second step estimated directions, which are values of estimated directions in which the object is present, are calculated for each of respective frequency bins in which the presence of the object has been confirmed by the frequency analysis executed in the first step. In a third step a theoretical curve is calculated which expresses a relationship between relative speed of a stationary object and directions in which the stationary object is present, with respect to the own vehicle. In a fourth step, the direction errors are obtained as errors of the estimated directions with respect to the theoretical curve."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Direction error detection method and apparatus using estimated directions, and in-vehicle radar apparatus","description":"A method of detecting direction errors of an object, applied to an in-vehicle radar apparatus, whereby in a first step, relative speeds of an object reflecting a continuous wave are obtained by execut","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10495743","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.
