The registration problem utilizes a singular value decomposition (SVD) method. The actual fusion of the constituent images employs a maximum likelihood (ML) decision rule methodology. This ML procedure is modified through the square of the errors (Chi square) but provides an optimal method to accept and reject candidate images for inclusion into the fused images. Numerical simulations show the applicability of the method.","PeriodicalId":305765,"journal":{"name":"Proceedings of the IEEE 2009 National Aerospace & Electronics Conference (NAECON)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128611358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reusable launch vehicle (RLV) program is one of such efforts to take the place of space shuttles for RLVs. Our previous research proposed a scheme of motion primitives (MPs) and neighboring optimal control (NOC) to deal with on-line failure recovery for an RLV during approach and landing (A&L). In this paper, more general system dynamics is employed and the extension of MPs and NOC used in the trajectory generation during both terminal area energy management (TAEM) and A&L is discussed.","PeriodicalId":305765,"journal":{"name":"Proceedings of the IEEE 2009 National Aerospace & Electronics Conference (NAECON)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128810417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper investigates the noise performance of an integrated source inductive degradation LNA, analyzes the noise contribution of its input matching inductors, and proposes a noise optimization method for the input matching network design of a power constrained LNA. The result was verified with a 2GHz LNA design in CMOS 0.18µm technology. When the current is constrained to a maximum of 3mA, the LNA achieves a noise figure of 3dB and an input return loss of −40dB.","PeriodicalId":305765,"journal":{"name":"Proceedings of the IEEE 2009 National Aerospace & Electronics Conference (NAECON)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124408623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
