The radar device (1) includes a path switching part (20) which outputs, as a calibration signal, to the frequency conversion part (12), the transmission signal output by the transmission signal generation part (11) at a timing while the transmission signal is output to the antenna (10). A gain adjustment part (23) changes an amplification gain of the frequency conversion part (12) on the basis of a signal level of the calibration signal input to the frequency conversion part (12) and a signal level of the calibration signal having been amplified by the frequency conversion part (12)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radar device and method for changing reception gain of radar device","description":"A radar device (1) includes a frequency conversion part (12) which converts a frequency of an echo signal obtained by reflecting a detection signal and receiving the reflected detection signal by an a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11307289","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.
