The performance parameters of interest are the coupling and mixing efficiencies of the lidar receiver, as they relate to the overall system carrier to noise ratio (CNR). The coupling efficiency relates the ability of the lidar receiver optics to couple light returning from a distant object into the multimode optical waveguide receiver. The energy thus received is then mixed with a local oscillator (LO) field in an evanescent wave coupler to generate the desired intermediate frequency (IF) signal current. The efficiency with which this mixing occurs is very strongly influenced by the receiver waveguide geometry, and thus the constituent modal structures of the guided LO and signal beam fields. Initial results indicate that for a symmetric square waveguide supporting seventy-five distinct modes, the coupling and mixing efficiencies can approach 78% and 23%, respectively. These results rival the performance characteristics of many free space and single mode waveguide lidar receiver designs, while higher efficiencies are expected for more realistic multimode waveguides supporting many more modes, and for lidar receivers constructed from circular (possibly graded index) multimode optical fiber waveguides.<<ETX>>","PeriodicalId":183796,"journal":{"name":"Proceedings of the IEEE 1993 National Aerospace and Electronics Conference-NAECON 1993","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125263001","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}

Most important the installation of a well structured software configuration management offers the buyer and seller protection against the myriad problems that often beset software development and maintenance projects that, if left unaccountable, can easily spell project disaster. This article states the candidate software configuration management (SCM) tasks to be performed during the software development life cycle. In performing the planning for SCM for any particular project, the tasks are in relationship to the statement of work for the development effort. With quality, in mind and a cost effective approach, only the tasks imposed by the contract will be selected from the candidate tasks and subtasks. This paper addresses major tasks, with each major task having its own esoteric subtasks. The major tasks presented in this paper are: 1. preparation of the SCM PLAN, 2. management of the SCM efforts, 3. performance of SCM configuration identification, 4. performance of SCM configuration control, 5. performance of SCM configuration status accounting, 6. support of SCM configuration audits.<<ETX>>","PeriodicalId":183796,"journal":{"name":"Proceedings of the IEEE 1993 National Aerospace and Electronics Conference-NAECON 1993","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129583634","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}
