面向雷达协同探测的无线通信组网理论与技术

Multi-radar cooperative detection is an important method of enhancing the performance of radars, such as detection range and detection accuracy et al. However, there are challenges on the insufficient of basic theory on radar-communication integration. In addition, the high-bandwidth transmission mechanism among the radars and the flexible cooperative networking are also severe problems needed to be addressed. The topic of this project belongs to an interdisciplinary research field. Specifically, the wireless communication and networking of multiple radars based on the autonomously adaptive technology is expected to propose in this project. The fundamental theory, models, mechanism and key technologies will be investigated for the wireless communication and networking of multiple radars: (1) The mechanism of multi-radar cooperative detection and information transmission will be investigated to address the performance bound of communication and networking for multi-radar cooperative detection based on the resource sharing scenario; (2) The method of communication and networking for multi-radar cooperative detection will be researched to settle the problems of high-bandwidth and low-delay for the adaptive networking in multi-radar cooperative detection upon the resource limited scenarios; (3) The mechanism of multi-domain resources management and control will be studied to solve the problem of dynamic and autonomous adaptation of the resources and diverse missions for multi-radar cooperative detection. (4) The simulation and experimental verification of the system will be completed. The project group is consisted of excellent team in domestic wireless communications and radar, which has good accumulation in the basic theory and key technique. Finally, the deliverables of this project will provide significant theoretical basis and technical supports of communication and networking for the development and application of multiple radar cooperative detection. In addition, it is meaningful to promote the research of radar-communication integration in our country.
