首先介绍了雷达的基本概念与发展历程，并面向民用雷达技术与产业发展的重大需求，介绍了雷达成像探测系统、微小目标探测系统和航天遥感技术等几种典型新体制民用雷达技术的研究进展与应用成果；并着重讨论了其关键科学问题与解决方案，预测了其技术与产业发展趋势；最后，对未来雷达探测的新机理（如量子雷达、微波光子雷达等）、新技术（如软件化、智能化、芯片化等）进行了展望。

This paper will first introduce the radar principles，history，development and the major demand for civil radar technology and industrial development. Then this paper will introduce the research progress and application of several typical civil radar technologies，such as radar imaging detection system，small target detection system and space remote sensing technology. Focusing on several novel radar systems and their key technologies，the key scientific issues and corresponding solutions，research progress and application，and future prospects are presented in details. Finally，the novel mechanisms of the future radar detection（such as quantum radar，microwave photonic radar，etc.）and new technologies（such as software oriented，Intellectualization oriented，chip，etc.）are prospected.
