摘　　要：遥测振动参数分析对于靶场导弹试验故障诊断和性能检测有着重要意义。双谱中包含了丰富的信号细微信息,且受高斯噪声和杂波影响较小,因此可以作为遥测振动参数分析的有力工具之一。文中采用双谱技术对遥测振动参数进行谱分析,并应用于多站位遥测振动参数的时延估计问题,通过实际应用验证了该方法有效可行,该方法具有重要的工程价值,为分析遥测振动参数提供了一种新的方法。The analysis of telemetry vibration parameters is of great significance for fault diagnosis and performance detection of missile test in firing range. The bispectrum contains rich signal fine information and is less affected by Gaussian noise and clutter,so it can be used as one of the powerful tools for telemetry vibration parameter analysis. This paper uses bispectrum technique to analyze telemetry vibration parameters,and it is also applied to the time delay estimation of the vibration parameters of multi-station telemetry. It has provided a new method for analyzing telemetry vibration parameters.
