摘要
设计了一种超宽带亚周期微波脉冲实时时频分析系统,可以大幅简化超短脉冲时频分析过程,并提高检测设备的实时性。这种方法利用高速示波器采集超短微波脉冲,通过LabVIEW与Matlab混合编程的方法对探测过程进行控制,并实时计算脉冲啁啾等时频特性。重点阐述了该系统的设计实现方法和具体应用场景。应用结果表明该系统稳定可靠、实时性良好和易于实现。相比传统分析设备,该系统具有更高的应用灵活性,在诸多领域具有广泛应用前景。
A real-time time-frequency analysis system for ultra-wideband(UWB) sub-cycle microwave pulses is presented, which simplifies the time-frequency analysis of UWB pulses to a large extent and improves the temporal response of analysis instruments for similar purposes. The system utilizes high-speed oscilloscope in sampling and recording an ultra-short microwave pulse, with control and real-time time-frequency chirp analysis realized via LabVIEW and Matlab programming. The design and materialization of the system, together with its typical applications, are presented. Tests and applications prove the system to be of good stability and temporal response, and easy to be built and maintained. Compared to conventional analysis systems, the presented system is more flexible, granting it good potential in various applications.
