Abstract

The invention belongs to the technical field of shortwave communication, and discloses a shortwave multi-path signal detection and concurrent processing system. The shortwave multi-path signal detection and concurrent processing system comprises a shortwave signal receiving subsystem, a data processing subsystem and m user terminals; the shortwave signal receiving subsystem comprises n receiving stations; each receiving station comprises a shortwave multi-path receiver, an antenna feeding system and a data pre-processing server; the data processing subsystem comprises a data fusion processing server and core switching equipment; the shortwave signal receiving subsystem is used for carrying out receiving and detection on multiple paths of concurrent shortwave signals; and the data processing subsystem is used for processing the multiple paths of concurrent shortwave signals. According to the shortwave multi-path signal detection and concurrent processing system disclosed by the invention, the problems that in the prior art, communication quality cannot be guaranteed and multiple paths of shortwave signals cannot be simultaneously detected, identified and processed can be solved, and when multiple paths of shortwave signals are concurrent, in a case of guaranteeing communication quality, multiple paths of shortwave signals can be simultaneously detected, identified and processed.

Description

technical field [0001] The invention relates to the technical field of short-wave communication, in particular to a short-wave multi-channel signal detection and concurrent processing system. Background technique [0002] Short-wave communication technology is a radio communication technology that uses the ionosphere for reflection to achieve long-distance communication through electromagnetic waves with a shorter wavelength (wavelength is 10m to 100m). The ionosphere is a plasma region produced by the ionization of the atmosphere under the action of high-energy particles. Solar activity, artificial interference, day and night, seasons, climate and other factors will have a certain impact on the ionosphere. [0003] In short-wave communication, the two parties need to agree on the communication frequency before communicating, and adjust the working frequency to the agreed frequency before receiving or sending short-wave signals. However, because short-wave communication rel...

Problems solved by technology

[0005] For this reason, the present invention provides a short-wave multi-channel signal detection and concurrent processing system to at least solve the problems that the prior art cannot guarantee communication quality and cannot simultaneously detect, identify and process multi-channel short-wave signals. When short-wave signals are concurrent, under the condition of ensuring the communication quality, it can detect, identify and process multiple short-wave signals at the same time
