The receive beam rotation processing for each antenna element includes application of rotation frequency offsets to the received signals and summation in summing and differencing adders to generate I and Q components of the rotating beams. The I and Q components for each element are summed to generate received signals including angle-or-arrival (AOA) information. The AOA information is further processed by correlating with reference replica AOA signals and by averaging to determine the actual AOA. The transmitter may have multiple contrarotating beams generated by application of frequency offsets. The transmit and receive beam rotations may be synchronized."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Super-angular and range-resolution with phased array antenna and multifrequency dither","description":"A radar system comprises an electromagnetic transmitter and an array of antenna elements connected in Multiple-Input Multiple-Output manner for routing signals reflected from the target to a plurality","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8466829","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.
