The receiving wave is formed from a reflection wave of the transmission wave reflected at the target. A beat signal generation unit is configured to generate beat signals in response to the transmission wave and the receiving wave. A frequency resolution processing unit is configured to obtain complex number data calculated from beat frequencies having signal levels obtained by performing a frequency resolution for the beat signals based on a predetermined frequency width. A peak detector is configured to detect an existence of the target by detecting peak signal levels of the beat frequencies, and a direction detecting unit is configured to calculate an incoming direction of the receiving wave based on a normal equation having an order."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic scanning radar apparatus, receiving wave direction estimating method, and computer-readable storage media storing receiving wave direction estimation program","description":"An electronic scanning radar apparatus includes a transmission unit configured to transmit a transmission wave, and a receiving unit including a plurality of antennas receiving a receiving wave coming","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8466830","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.
