目标多样化、环境复杂化和任务多元化,促进了雷达体制、雷达理论和雷达技术的不断发展。文中从探测器的构型、 观测视角覆盖和信号空间维度3个方面,分析了雷达技术发展的演进过程,并提出了未来20年内第5代雷达的发展趋势, 即网络化、协同化、智能化。重点介绍了代表第5代雷达发展方向的典型系统,包括多输入多输出雷达、认知雷达和凝视 雷达。该文对雷达技术发展具有重要的参考价值。

Radar system, theory and technology are continuously developed under the requirement of diverse target, complicated environment and multiple mission. The evolution of radar is analyzed from three aspects of detector composition, observation angle coverage and signal subspace dimension, and the developing tendency of the 5th generation of radar in the next 20 years is presented, which is networked, cooperative and intelligent. The multiple-input multiple-output (MIMO) radar, cognitive radar and gazing radar are studied respectively, which are typical system of the 5th generation of radar. This paper is of great significance to guide radar development.
