摘要
现代隐身技术的发展给有源预警探测体系带来了极大的挑战,现代航空技术的进步,使得高机动、超低空、高等级威胁的进攻武器对防空反导的超前预警提出了更高的要求。为了满足在复杂电磁环境以及在隐身技术常用的突发性通信手段下实现信号侦察检测的要求,基于FFT宽频段内信号监测,提出了基于FFT幅度谱统计分析的突发信号检测技术。该技术对目前预警探测系统实际情况中的信号侦察技术进行了研究,对完善预警探测网络体系建设提供了技术支撑。
The development of modern stealth technology brings a great challenge to active early warning detection system. The advancement of modern aerotechnics puts forward higher requirements to air-defense and anti-missile system’ s advance warning to fight the offensive weapon with high maneuverability,very low-altitude and high level of threat.To implement signal reconnaissance and detec-tion in the complex electromagnetic environment or in means of burst communication used by the stealth equipment,this paper puts for-ward a new burst signal detection method based on FFT amplitude spectrum statistic analysis technology to recognize targets. Based on analysis of actual situation of early warning detection system,the study on military signal reconnaissance provides technical support for the improvement of early warning detection system construction.
