Description

technical field [0001] The invention relates to the field of communication signal analysis and identification, in particular to a fixed-frequency signal reorganization method based on frequency spectrum monitoring data. Background technique [0002] Through the monitoring of surrounding electromagnetic signals, in conjunction with surrounding wireless frequency resources, and based on the characteristics of target electromagnetic signals, the recognition and identification of radiation sources is realized. Provide data support for planning and frequency management and control. [0003] Technical research on radiation source identification using fingerprint feature mechanism has been carried out at home and abroad, but it is difficult to define the fingerprint feature of radiation source, it is difficult to extract fingerprints, and it is easily affected by propagation environment factors such as receiver system and multipath. Most of the relevant research is in the laborator...
