Previous work has shown that a feedforward network of nonlinear oscillators can lead, in principle, to a novel beamforming system, in which the collective dynamics of the network can produce, simultaneously, signal amplification and beam steering capabilities through phase-locking solutions. These two features can find applicability in future design and fabrication of modern antenna and radar systems. We now investigate the response of the feedforward network of oscillators, and the beamforming pattern, to an incoming signal. The study shows, in particular, that synchronization with an incoming signal can yield a beamforming pattern with a narrow mainlobe and lower sidelobes. These are desirable features because they can lead to improved resolution and less susceptibility to interference by strenuous signals. <\/jats:p>","DOI":"10.1142\/s0218127425300046","type":"journal-article","created":{"date-parts":[[2025,1,28]],"date-time":"2025-01-28T05:25:58Z","timestamp":1738041958000},"source":"Crossref","is-referenced-by-count":1,"title":["Beam Steering and Signal Amplification Through Feedforward Networks: Part II Reception"],"prefix":"10.1142","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-5034-7566","authenticated-orcid":false,"given":"Tyler","family":"Levasseur","sequence":"first","affiliation":[{"name":"Kochava Inc., Sandpoint, ID 83864, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0580-3657","authenticated-orcid":false,"given":"Antonio","family":"Palacios","sequence":"additional","affiliation":[{"name":"Nonlinear Dynamical Systems Group, Department of Mathematics, San Diego State University, San Diego, CA 92182, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-7822-0057","authenticated-orcid":false,"given":"Shashwat","family":"Sharan","sequence":"additional","affiliation":[{"name":"Department of Applied Mathematics, University of California, Merced, CA 95343, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-2556-6449","authenticated-orcid":false,"given":"Visarath","family":"In","sequence":"additional","affiliation":[{"name":"Naval Information Warfare Center Pacific, Code 71780, 53560 Hull Street, San Diego, CA 92152-5001, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2025,1,25]]},"reference":[{"key":"S0218127425300046BIB001","doi-asserted-by":"publisher","DOI":"10.1137\/050635559"},{"key":"S0218127425300046BIB002","doi-asserted-by":"publisher","DOI":"10.1117\/12.562903"},{"key":"S0218127425300046BIB003","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4419-0389-1_6"},{"key":"S0218127425300046BIB004","doi-asserted-by":"publisher","DOI":"10.3934\/dcds.2012.32.2913"},{"key":"S0218127425300046BIB005","doi-asserted-by":"publisher","DOI":"10.1002\/9780470529188"},{"key":"S0218127425300046BIB007","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127400001614"},{"key":"S0218127425300046BIB009","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127421500309"},{"key":"S0218127425300046BIB010","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127422300348"},{"key":"S0218127425300046BIB011","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.98.254101"},{"key":"S0218127425300046BIB012","doi-asserted-by":"publisher","DOI":"10.1109\/JPROC.2002.1015012"},{"key":"S0218127425300046BIB013","doi-asserted-by":"publisher","DOI":"10.1002\/9783527635801"},{"key":"S0218127425300046BIB014","doi-asserted-by":"publisher","DOI":"10.1109\/22.754880"},{"key":"S0218127425300046BIB015","doi-asserted-by":"publisher","DOI":"10.1109\/TMTT.1986.1133491"},{"key":"S0218127425300046BIB016","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.1987.1144184"},{"key":"S0218127425300046BIB017","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4757-4067-7"},{"key":"S0218127425300046BIB018","doi-asserted-by":"publisher","DOI":"10.1109\/22.247926"},{"key":"S0218127425300046BIB019","doi-asserted-by":"publisher","DOI":"10.1109\/22.734513"},{"key":"S0218127425300046BIB020","doi-asserted-by":"publisher","DOI":"10.1137\/10078637X"}],"container-title":["International Journal of Bifurcation and Chaos"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218127425300046","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,27]],"date-time":"2025-02-27T09:51:38Z","timestamp":1740649898000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/10.1142\/S0218127425300046"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,1,25]]},"references-count":18,"journal-issue":{"issue":"02","published-print":{"date-parts":[[2025,2]]}},"alternative-id":["10.1142\/S0218127425300046"],"URL":"https:\/\/doi.org\/10.1142\/s0218127425300046","relation":{},"ISSN":["0218-1274","1793-6551"],"issn-type":[{"type":"print","value":"0218-1274"},{"type":"electronic","value":"1793-6551"}],"subject":[],"published":{"date-parts":[[2025,1,25]]},"article-number":"2530004"}}
