In some implementations, the approximated three-dimensional beampattern comprises a main lobe that includes a look direction for which waveforms detected by a sensor array are not suppressed and a side lobe that includes other directions for which waveforms detected by the microphone array are suppressed. The one or more constraints can include a constraint that suppression of waveforms received by the sensor array from the side lobe are greater than a threshold. In some implementations, the threshold can be dependent on at least one of an angular direction of the waveform and a frequency of the waveform."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Beamformer design using constrained convex optimization in three-dimensional space","description":"Embodiments of systems and methods are described for determining weighting coefficients based at least in part on using convex optimization subject to one or more constraints to approximate a three-di","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9591404","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.
