| 2 | Impact time control guidance against maneuvering targets based on a nonlinear virtual relative model显示文摘Aiming at the problem of high-precision interception of air-maneuvering targets with impact time constraints,this paper proposes a novel guidance law based on a nonlinear virtual relative model in which the origin is attached to the target.In this way,the original maneuvering target is transformed into a stationary one.A polynomial function of the guidance command in the range domain with two unknown coefficients is introduced into the virtual model,one of the coefficients is determined to achieve the impact time constraint,and the other is determined to satisfy a newly defined virtual look angle constraint.For meeting the terminal constraints simultaneously,the guidance command can finally be obtained.The resulting solution is represented as a combination of proportional navigation guidance-like term which is aimed to meet the zero miss distance constraint,a bias term for impact time control by adjusting the length of the homing trajectory,and an additional term for target maneuvers.Numerous simulations demonstrate that the proposed law achieves an acceptable impact time error for various initial conditions against different types of maneuvering targets and shows more effective performance in comparison with those of other existing guidance laws. | Yuru BIN Hui WANG Defu LIN Yaning WANG Xin SUN | 2023 | Chinese Journal of Aeronautics2023，36，7： | 0 |
| 3 | Development of Rural Tourism in Liaoning Province from the Perspective of Types显示文摘With the vigorous development of the tourism industry,the types of tourism become rich and diverse,and the development models have their own characteristics.At present,rural tourism has become a hot spot in the development of tourism,and it is also a driver of rural revitalization.However,its development type and development model are not mature yet,and there are still some fundamental problems in the process of development.Based on the development status of rural tourism in Liaoning Province,an in-depth survey was carried out on the types and development models of rural tourism in Liaoning Province,and its basic types and development models are clarified,to explore the deep-rooted problems existing in the development of rural tourism in Liaoning Province.Besides,the development models adopted in different regions of China were compared to find the universally applicable rules for the development of rural tourism.Finally,according to the distribution of rural tourism resources,the development direction was clearly defined,supporting policy recommendations were proposed,including adjusting and upgrading the existing types and development models,and implementing development strategies in a targeted manner to promote the sustainable development of rural tourism in Liaoning Province. | Siyu WANG Liang ZHAO Na SAI Yaning HUI | 2021 | Asian Agricultural Research2021，13，9： | 0 |
