我国近地小行星地基雷达探测系统性能设计和仿真分析

Performance and Simulation of the Ground-Based Radar System for NEA in China

利用地基雷达系统进行近地小行星探测具有独特的技术优势,也是行星防御不可或缺的技术手段。本文以此为背景,分析了国内地基雷达自主研发技术能力,探讨了我国近地小行星地基雷达探测系统的性能设计,并针对近地小行星探测的能力和范围开展了仿真分析。同时结合我国深空测控网和射电天文网的技术现状及未来的发展规划,对后续开展近地小行星地基雷达联合探测途径进行了探讨。

It has unique technical advantages to use the ground-based radar system for tracking near Earth asteroid(NEA).And it is also an indispensable technique for asteroid security defense.In this paper,we analyze the independent development and optimized capability of domestic ground-based radar and simulate its performance for NEA monitoring.In collaboration with the deep space TT&C(tracking,telemetry and command)network and radio astronomy network,the joint detection of NEA is very prospective in China.
