Problems solved by technology

[0005] However, the existing technology still has obvious deficiencies in the analysis technology of electromagnetic interference of frequency hopping interference signals. It only discusses the general idea of ​​electromagnetic interference analysis between frequency-using equipment, and the proposed method stays at the system framework level and does not target specific users. It is difficult to meet the requirements for accurate analysis of the electromagnetic interference of frequency hopping interference signals by establishing corresponding analysis and calculation models for frequency modes and signal formats
