深空探测是空间技术研究的重要组成部分,通过对深空目标的探测,可以为人类可能面临的太空威胁提供预报,也可为人类的空间活动提供安全保证.雷达已成为深空探测的重要设备.文中分析了空间目标分布特性和国外空间目标探测雷达技术的发展趋势,提出了发展深空目标探测雷达需要注重研究的关键技术.

Deep-space detection is an important part of research in space technology. By detecting the deep-space targets, we can provide to humans alarms of danger from the deep-space and assure personal safety for the actions in deep-space. Radar has already became one of the most important equipments for deep-space detection. This paper analyzes the distribution characteristic of space targets and development trends of foreign technology for space target detect radar. Furthermore, it puts forward some critical technologies which should be studied intensively energetically in the development of space target detect radar.
