    • A spectrum analysis engine (SAGE) that comprises a spectrum analyzer component, a signal detector component, a universal signal synchronizer component and a snapshot buffer component. The spectrum analyzer component generates data representing a real-time spectrogram of a bandwidth of radio frequency (RF) spectrum. The signal detector detects signal pulses in the frequency band and outputs pulse event information entries output, which include the start time, duration, power, center frequency and bandwidth of each detected pulse. The signal detector also provides pulse trigger outputs which may be used to enable/disable the collection of information by the spectrum analyzer and the snapshot buffer components. An alternative pulse detection module is provided that tracks signal pulses by comparing peak data from successive FFT cycles with existing signal pulse data that is derived from comparing peak data for prior FFT cycles. Peaks for new FFT cycles are matched to data associated with signal pulses determined to be occurring over many FFT intervals.
    • 频谱分析引擎(SAGE),包括频谱分析仪组件,信号检测器组件,通用信号同步器组件和快照缓冲器组件。 频谱分析仪组件产生表示射频(RF)频谱带宽的实时谱图的数据。 信号检测器检测频带中的信号脉冲,并输出脉冲事件信息条目输出,其中包括每个检测脉冲的开始时间,持续时间,功率,中心频率和带宽。 信号检测器还提供脉冲触发输出,可用于启用/禁用频谱分析仪和快照缓冲器组件的信息采集。 提供了替代脉冲检测模块,其通过将来自连续FFT周期的峰值数据与从先前FFT周期的比较峰值数据导出的现有信号脉冲数据进行比较来跟踪信号脉冲。 用于新的FFT周期的峰值与确定为在许多FFT间隔上发生的信号脉冲相关联的数据匹配。
