| 摘要: |
| 预警雷达一直是战场防空和国土防御的基本装备之一，而隐身飞行器的出现迫使现代预警雷达必须提高其反隐身能力。首先从雷达的工作频率、目标的极化信息和非后向散射特性剖析了现代预警雷达的反隐身关键技术，然后根据不同的雷达体制对典型反隐身预警雷达进行分类综述，最后总结了多输入多输出、低截获概率、太赫兹超宽带、微波光子相控阵、第三代半导体和基于数学模型的网络优化等新技术的特点和难点，并展望了反隐身预警雷达需进一步研究的方向，以期为反隐身预警雷达相关设计人员提供一定的帮助和参考。 |

| Abstract: |
| The early warning radar(EWR) has been one of the basic equipment of air defense both on the battlefield and the national territory. The appearance of the stealth aircraft forces the modern EWR to enhance its anti-stealth ability. First the anti-stealth key technology of modern EWR is listed in terms of the radar’s working frequency,the target’s polarization information and non-backscattering characteristics. Then typical EWRs are classified and clarified according to different radar systems. To predict the possible trends of future EWR,characteristics and challenges of new technology are summarized,including multiple-input multiple-output(MIMO),low probability of interception(LPI),terahertz ultra-wideband(THz UWB),microwave optics phased array,the third generation of semiconductor and network optimization based on mathematical models,and open issues for future research on EWR are pointed out. All of these are supposed to provide some help and reference for designing anti-stealth EWRs. |
