| 1 | Optimal allocation of multi-sensor passive localization显示文摘To improve multi-sensor passive localization precision,the optimal allocation form of multi-sensor bearing-only localization is analyzed from the perspective of the geometric dilution of precision(GDOP) of the least squares(LS) algorithm.This paper indicates that whether the target lies inside the closed region formed by the sensors or not,the optimal allocation is when each adjacent cut angle between a sensor pair is identical,and all sensors are located on the border of the circle that has the target(which is also the origin of the coordinate system) as its center.When there is no restriction on the adjacent cut angle in the above allocation,the optimal estimate of the LS algorithm in the sense of minimum variance can be acquired.When the LS algorithm achieves the optimal estimate and the sensors present the optimal allocation,the respective consistencies are analyzed.Simulation results verify the analysis of the optimal allocation form above,which can be used in multi-sensor passive localization algorithms based on sensor management. | WANG BenCai HE You WANG GuoHong XIU JianJuan | 2010 | Science China(Information Sciences)2010，53，12： | 11 |
| 2 | High-entropy alloy nanoparticles as a promising electrocatalyst to enhance activity and durability for oxygen reduction显示文摘Developing efficient platinum-based electrocatalysts with super durability for the oxygen reduction reaction(ORR)is highly desirable to promote the large-scale commercialization of fuel cells.Although progress has been made in this aspect,the electrochemical kinetics and stability of platinum-based catalysts are still far from the requirements of the practical applications.Herein,PtPdFeCoNi high-entropy alloy(HEA)nanoparticles were demonstrated via a high-temperature injection method.PtPdFeCoNi HEA nanocatalyst exhibits outstanding catalytic activity and stability towards ORR due to the high entropy,lattice distortion,and sluggish diffusion effects of HEA,and the HEA nanoparticles delivered a mass activity of 1.23 A/mgPt and a specific activity of 1.80 mA/cmPt 2,which enhanced by 6.2 and 4.9 times,respectively,compared with the values of the commercial Pt/C catalyst.More importantly,the high durability of PtPdFeCoNi HEA/C was evidenced by only 6 mV negativeshifted half-wave potential after 50,000 cycles of accelerated durability test(ADT). | Yanan Yu Fanjie Xia Chengjie Wang Jinsong Wu Xianbiao Fu Dongsheng Ma Bencai Lin Jiaao Wang Qin Yue Yijin Kang | 2022 | Nano Research2022，15，9： | 1 |

| 12 | Adaptive detection of range-spread targets in homogeneous and partially homogeneous clutter plus subspace interference显示文摘Adaptive detection of range-spread targets is considered in the presence of subspace interference plus Gaussian clutter with unknown covariance matrix.The target signal and interference are supposed to lie in two linearly independent subspaces with deterministic but unknown coordinates.Relying on the two-step criteria,two adaptive detectors based on Gradient tests are proposed,in homogeneous and partially homogeneous clutter plus subspace interference,respectively.Both of the proposed detectors exhibit theoretically constant false alarm rate property against unknown clutter covariance matrix as well as the power level.Numerical results show that,the proposed detectors have better performance than their existing counterparts,especially for mismatches in the signal steering vectors. | JIAN Tao HE Jia WANG Bencai LIU Yu XU Congan XIE Zikeng | 2024 | Journal of Systems Engineering and Electronics2024，35，1： | 0 |
