| 1 | Multiple model efficient particle filter based track-before-detect for maneuvering weak targets显示文摘It is a tough problem to jointly detect and track a weak target, and it becomes even more challenging when the target is maneuvering. The above problem is formulated by using the Bayesian theory and a multiple model(MM) based filter is proposed. The filter presented uses the MM method to accommodate the multiple motions that a maneuvering target may travel under by adding a random variable representing the motion model to the target state. To strengthen the efficiency performance of the filter,the target existence variable is separated from the target state and the existence probability is calculated in a more efficient way. To examine the performance of the MM based approach, a typical track-before-detect(TBD) scenario with a maneuvering target is used for simulations. The simulation results indicate that the MM based filter proposed has a good performance in joint detecting and tracking of a weak and maneuvering target, and it is more efficient than the general MM method. | BAO Zhichao JIANG Qiuxi LIU Fangzheng | 2020 | Journal of Systems Engineering and Electronics2020，31，4： | 7 |

| 7 | Properties of Gauss-Newton filter in linear cases显示文摘This paper presents the derivation of Gauss-Newton filter in linear cases and an analysis of its properties. Based on the minimum variance theorem, the Gauss-Newton filter is constructed and derived, including its state transition equation, observation equation and filtering process. Then, the delicate relationship between the Gauss-Aitken filter and the Kalman filter is discussed and it is verified that without process noise the two filters are equivalent. Finally, some simulations are conducted. The result shows that the Gauss-Aitken filter is superior to the Kalman filter in some aspects. | BAO Zhichao JIANG Qiuxi | 2018 | Journal of Systems Engineering and Electronics2018，29，5： | 0 |
| 8 | Effects of Polysaccharides from Enteromorpha prolifera on Hepatorenal Syndrome in Mice显示文摘[Objectives]This study was conducted to evaluate the protective effect of polysaccharides from Enteromorpha prolifera(PEP)on mice with hepatorenal syndrome induced by carbon tetrachloride.[Methods]A mouse hepatorenal syndrome model was induced by carbon tetrachloride.The serum levels of lipid,total antioxidant capacity,liver and kidney function,pathological changes of liver and kidney were selected to clarity the effectiveness of PEP on hepatorenal syndrome in mice.[Results]PEP effectively lowered the serum levels of lipid,increased total antioxidant capacity,improved liver and kidney injury,and alleviated pathological changes of liver and kidney of mice induced by carbon tetrachloride.[Conclusions]PEP has a potent preventive effect on hepatorenal syndrome induced by carbon tetrachloride in mice,which provides theoretical support for future clinical application of PEP. | Shanshan WANG Jiayan ZHOU Yue HE Yating ZHOU Qiuxi YANG Qianqian YUAN Qingying DU Hanchi CHENG Suduo JIANG Xiaojuan ZHAO | 2023 | Medicinal Plant2023，14，1： | 0 |
