Accordingly, it is possible to improve the quality of calculated wind field using the improved radar radial velocity, and provide more accurate dynamic structure information of the precipitation system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for retrieval of lost radial velocity in weather radar, recording medium and device for performing the method","description":"A method for retrieval of lost radial velocity in weather radar includes expanding a radial velocity area to non-meteorological echoes including sea clutter and chaff echo using raw radar data for use","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11474237","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.
