| 1 | Multichannel adaptive signal detection:basic theory and literature review显示文摘Multichannel adaptive signal detection uses test and training data jointly to form an adaptive detector to determine whether a target exists.The resulting adaptive detectors typically possess constant false alarm rate(CFAR)properties;thus,no additional CFAR processing is required.In addition,a filtering process is also not required because the filtering function is embedded in the adaptive detector.Adaptive detection typically exhibits better detection performance than the filtering-then-CFAR detection technique.It has been approximately 35 years since the first multichannel adaptive detector was proposed by Kelly in 1986.However,there are few overview articles on this topic.Thus,in this study,we present a tutorial overview of multichannel adaptive signal detection with an emphasis on the Gaussian background.We discuss the main design criteria for adaptive detectors,investigate the relationship between adaptive detection and filtering-then-CFAR detection techniques,investigate the relationship between adaptive detectors and adaptive filters,summarize typical adaptive detectors,present numerical examples,provide a comprehensive literature review,and discuss potential future research tracks. | Weijian LIU Jun LIU Chengpeng HAO Yongchan GAO Yong-Liang WANG | 2022 | Science China(Information Sciences)2022，65，2： | 13 |
| 2 | Different responses of arbuscular mycorrhizal fungal community to day-time and night-time warming in a semiarid steppe显示文摘Arbuscular mycorrhizal(AM) fungi form mutualistic symbioses with most plant species and play important roles in ecosystems.Knowledge of the response of AM fungi to temperature change will improve our understanding of the function of AM fungal community under global climate change scenarios in ecosystems.The effects of constant warming on AM fungal communities have been investigated previously,but responses to asymmetrical warming over 24-h periods have never been documented in natural ecosystems.In this study,we examined AM fungal communities in a full factorial design including day-time and night-time warming in a semiarid steppe in northern China.Day-time and 24-h warming,but not night-time warming,significantly increased AM fungal spore density.In contrast,none of the three warming regimes had a significant effect on AM fungal extra radical hyphal density.Atotal of 161 operational taxonomic units(OTUs) of AM fungi were recovered by 454 pyrosequencing of 18 S r DNA.Day-time,night-time,and 24-h warming all significantly increased AM fungal OTU richness.Some AM fungal OTUs showed a significant bias toward day-time,night-time or24-h warming.The AM fungal community composition was significantly affected by night-time warming,but not by day-time and 24-h warming.Our finding highlighted different responses of AM fungal spore density and community composition to asymmetrical warming.This study might improve our understanding of ecosystem functioning of AM fungal community under global climate change scenarios in a semiarid steppe ecosystem. | Yongchan Kim Cheng Gao Yong Zheng Wei Yang Liang Chen Xinhua He Shiqiang Wan Liang-Dong Guo | 2014 | Chinese Science Bulletin2014，59，35： | 4 |
