The shortwave / ultrashort wave real-time dynamic spectrum detection system includes: a radio frequency switch, a spectrum analysis display module, an ultrashort wave antenna for receiving ultrashort wave signals, and a short wave antenna for receiving short wave signals; the radio frequency switch is a single pole double throw switch, so The radio frequency switch is provided with a first input terminal, a second input terminal, an output terminal, and a control terminal, the control terminal of the radio frequency switch accesses the radio frequency switch control signal, and the first input terminal of the radio frequency switch is electrically connected to the ultrashort wave antenna, The second input end of the radio frequency switch is electrically connected to the short-wave antenna, and the output end of the radio frequency switch is electrically connected to the input end of the spectrum analysis display module.

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...

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 detected Limited (i.e. poor sensitivity), low resolution
