In the precipitation determining process, in the absence of objects other than precipitation objects from a transmission range of the radar wave, it is determined whether a spectral similarity of the frequency spectra of the rising and falling section with precipitation reference spectra is not less than a threshold, and if the spectral similarity is not less than the threshold as a result of the determination, it is determined that precipitation is present."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Precipitation determining device","description":"A radar device includes a transmission part that transmits a radar wave which has been frequency-modulated such that one measurement cycle has a rising section in which a frequency increases and a fal","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10473774","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.
