Moreira (1991; 1992; 1994). A triangular window is obtained by cascading two rectangular windows of the same length. It is shown that if their lengths are chosen to differ, an improved sidelobe performance is obtained at no computational cost. A further improvement is obtained by using three cascaded rectangular windows. The technique can be expected to improve SAR images obtained using this efficient algorithm.<<ETX>>","PeriodicalId":302763,"journal":{"name":"Proceedings Electronic Technology Directions to the Year 2000","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130192804","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}

Therefore, decompositional implementation of large functions is not a choice but a real necessity in this case. The objective of the new decomposition method presented is to implement a complex Boolean function or an assigned sequential machine with a minimal number of constrained building blocks and minimal connections between the blocks. The method aims at solving problems with hard constraints in multiple dimensions. It differs substantially from the methods for solving similar simpler one dimensional problems. The method is very general and, after some small changes, it can be applied to many other partitioning problems. The experimental results show that the method is very efficient.<<ETX>>","PeriodicalId":302763,"journal":{"name":"Proceedings Electronic Technology Directions to the Year 2000","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116523838","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}

In these techniques, the higher order statistics (3rd and 4th order \"cumulants\") that provide the information regarding deviation from Gaussianity and presence of phase relations of a signal have been discarded. In the sequel, the performance of these techniques is limited. Recently, artificial neural network techniques based on non-linear function and also independent of signal model have been proposed in the literature. A comparative analysis is carried out in this paper for a high resolution MLM and three ANN techniques. The Hopfield neural network, backpropagation neural network and radial basis function networks are described. Computer simulation results have demonstrated that nonlinear adaptive (ANN) techniques have more superior performance.<<ETX>>","PeriodicalId":302763,"journal":{"name":"Proceedings Electronic Technology Directions to the Year 2000","volume":" 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113949533","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 is based on the researchers' perspectives on where technology will go during the next ten years, how this will affect people and institutions and the competitive environment in the information industry. The year 2000 is only five years away and we can make pretty accurate projections of where technology will be at the end of the twentieth century. In an industry that is as dynamic as ours it is much more difficult to project progress over a ten year horizon and it is particularly hard to foresee how this progress will translate into societal and institutional changes. As Yogi Berra, a famous American baseball player and amateur philosopher, said, \"the future isn't what it used to be\". Our challenge is to make it what we want it to be.<<ETX>>","PeriodicalId":302763,"journal":{"name":"Proceedings Electronic Technology Directions to the Year 2000","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117070703","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}

Under the assumptions for target types the dithering the carrier centre frequency enhances the classification performance for targets typically 5 dB above the average image intensity.<<ETX>>","PeriodicalId":302763,"journal":{"name":"Proceedings Electronic Technology Directions to the Year 2000","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115680631","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}
