An array of N antenna elements is provided, the array of antenna elements each having an associated two state modulator coupled therewith. Energy received at the array is modulated according to a sequence of multibit codes, the number of codes in the sequence of codes comprising at least K times Q times N, thereby reducing noise in the coded aperture radar system compared to a coded aperture radar system radar system having fewer than K times Q times N codes in its sequence of multibit codes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for reducing noise in a coded aperture radar","description":"A method and apparatus for reducing noise in a coded aperture radar system, the coded aperture radar system transmitting signals which occur in sweeps, with K sweeps utilized to cover field of view of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9658321","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.
