摘　　要：低截获概率雷达信号具有低功率、大带宽、复杂调制等特点,传统的电子侦察系统难以对其进行感知。研究了多维联合相干处理、高分辨率检测处理、实时脉内调制分析等关键技术,可实现对低截获概率雷达信号的侦收、检测及识别,提升了电子侦察系统对低截获概率雷达信号的感知能力。Low probability of intercept(LPI)radar signal is characterized by low power,large bandwidth and complex modulation,which is difficult to be sensed by traditional electronic reconnaissance system.For the above problems,the key technologies of multi-dimensional joint coherence processing,high-resolution detection pro⁃cessing and real-time intra-pulse modulation analysis are studied.The reception,detection and recognition of LPI radar signal can be realized by these technologies.The capability of electronic reconnaissance system to detect LPI radar signal is improved.
