With appropriate analogical reasoning, it can be applied to all kinds of radars and antennas. It breaks the ordinary belief that an array of N antennas can only generate N pictures of spectral for analysis. Without the need of improvement on the system hardware, BASICS assumes many virtual movements of array antenna in order to produce enough linear equations describing Doppler modulations of targets' spectra by those of the virtual movements, and the solutions would give accurate DOA information of possible targets. This invention presents the principle of BASICS and its theoretical supports, as well as the basic conditions to apply BASICS."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Direction finding technique in radar array signal processing","description":"This invention describes a new Direction Finding (DF) algorithm named as Braided Array Sampling via an Inter-Channel Scheme (BASICS) that can enhance estimation accuracy of the direction of arrival (D","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11977152","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.
