The real polarization scattering matrix (PSM) namely Sinclair scattering matrix must be acquired by instantaneous full polarization measurements. For the requirement of full polarization measurement to radar targets instantaneously, a solution to the two key issues on channel isolation and sidelobe suppression is proposed here from the perspective of waveform design and echo processing. The required waveform characteristics for instantaneous full polarization radar and the demands of sidelobe suppression performance were reviewed. Channel isolation is guaranteed by orthogonal Waveform Design, and the performance of auto-correlation and Doppler tolerance is obtained at the same time. A novel signal transmission guideline is designed based on comprehensive utilization of positive and negative chirp rate linear frequency-modulation (LFM) waveform and orthogonal phase-coded waveform hopping pulse to pulse randomly. Effective sidelobe reduction is achieved by inter-pulse information processing. What's more, the signal-to-noise ratio (SNR) and the performance of low probability of intercept radar are improved simultaneously.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"3 1 1","pages":"689-693"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89658278","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}

By far, the subject-specific ICA, temporal concatenation method and tensor PICA have been applied to fMRI data analysis. Among the three methods, both temporal concatenation method and tensor PICA are the most widely used. However, there hasn't been any comparison of subject-specific ICA, temporal concatenation method and tensor PICA. The current study aims at comparing the three group ICA methods at various noise levels. Simulated experiment based on human resting fMRI data revealed that tensor PICA provided the best overall performance due to the highest spatial detection power and relatively more accurate estimation of time course. Temporal concatenation method provided moderate performance in terms of relatively higher spatial detection power and simpler algorithm. Subject-specific method showed the worst spatial detection power and was the most time consuming in component selection.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"37 1","pages":"1276-1280"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86360752","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}
