Description

technical field [0001] The invention belongs to the technical field of shortwave / ultrashortwave spectrum detection and analysis, and in particular relates to a shortwave / ultrashortwave real-time dynamic spectrum detection system and method. Background technique [0002] Due to the increasing noise and interference in the wireless communication environment, the existing shortwave / ultrashortwave radio stations are faced with a more complex electromagnetic environment than ever before in actual use, and it is often impossible to find reliable and high-quality radio stations in the first place. communication frequency. In the existing shortwave / ultrashortwave spectrum detection and analysis methods, the shortwave spectrum and the ultrashortwave spectrum need to be detected and analyzed separately, and the spectrum analysis is usually performed at the RF front end. The spectrum detection and analysis of the signal at the RF front end results in the smallest signal that can be det...
