| description | This invention discloses a method for detecting weak low-frequency signals in unknown frequency conversion signals; the method of the invention firstly divides the input unknown frequency conversion signals into two paths, wherein, one path enters a data acquisition system, the other path is used for producing tracing trigger signals, then the tracing trigger signals are used for realizing the triggering and acquisition of the unknown frequency conversion signals which are analyzed and processed, thus realizing the detection of weak low-frequency signals in unknown frequency conversion signals. The method of the invention has little dependence on the prior knowledge of the background signal characteristics, small analytical data length, low sampling rate and high real-time data processingand is very applicable to the extraction and detection of weak signals. |
