Vaishali attacked the problems from three broad categories: iterative missing data recovery, adaptive local filtering based approach, and signal stationarization-based approaches. The dissertation also develops knowledge-based time-frequency representations based on signal stationarization and applies them for the Doppler analysis of over-the-horizon radar (OTHR) signals.<\/p>\n<p>Vaishali&#8217;s Ph.D. studies were partially supported by the Air Force Research Laboratory.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ms. Vaishali Amin has successfully defended her Ph.D. dissertation, \u201cTime-Frequency Analysis Techniques for Non-Stationary Signals Using Sparsity,\u201d on April 5, &hellip;<\/p>\n","protected":false},"author":7519,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-779","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/sites.temple.edu\/aspl\/wp-json\/wp\/v2\/posts\/779","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sites.temple.edu\/aspl\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sites.temple.edu\/aspl\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sites.temple.edu\/aspl\/wp-json\/wp\/v2\/users\/7519"}],"replies":[{"embeddable":true,"href":"https:\/\/sites.temple.edu\/aspl\/wp-json\/wp\/v2\/comments?post=779"}],"version-history":[{"count":0,"href":"https:\/\/sites.temple.edu\/aspl\/wp-json\/wp\/v2\/posts\/779\/revisions"}],"wp:attachment":[{"href":"https:\/\/sites.temple.edu\/aspl\/wp-json\/wp\/v2\/media?parent=779"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sites.temple.edu\/aspl\/wp-json\/wp\/v2\/categories?post=779"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sites.temple.edu\/aspl\/wp-json\/wp\/v2\/tags?post=779"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
