An ultrashort wave broadband monitoring system and method

Abstract

The invention discloses an ultrashort wave broadband monitoring system and method. The system includes an ultrashort wave broadband monitoring receiver, broadband pre-classification equipment, multi-channel processing equipment, system control management equipment, monitoring work seats and a network switch. Compared with the prior art, the present invention provides a radio monitoring system solution that can be customized for user needs, has high flexibility, scalability and modularization characteristics, and can be used for fixed, mobile and mobile platform carriers. It integrates multiple functions such as fast signal search, signal interception, signal identification, broadband recording, and offline analysis. A variety of manual interactive working modes can be widely used in the spectrum monitoring work of local and military radio management departments.

Description

technical field [0001] The invention relates to the field of monitoring systems, in particular to an ultrashort wave broadband monitoring system and method. Background technique [0002] The E3238S system of American Agilent Company has a variety of search modes, and adopts various methods such as level, automatic and environment to estimate noise, so as to realize active signal monitoring. The alarm settings are flexible and diverse, with multiple functions such as modulation identification, demodulation, playback, and data recording. The real-time monitoring bandwidth can reach 36MHz, and it has automatic and manual working modes. [0003] The GX435 of German RS company has the function similar to Agilent E3238S system. [0004] But in China, there is no system similar to E3238S and GX435. Although there are some systems that detect and automatically control specific signals, compared with E3238S and GX435, their functions cannot be compared. [0005] The main technical ...

Problems solved by technology

[0004] But in China, there is no system similar to E3238S and GX435. Although there are some systems for detecting and automatically controlling specific signals, compared with E3238S and GX435, their functions cannot be compared.

[0005] The main technical problems in this technical field: first, whether the network transmission of the ultrashort wave broadband monitoring system can meet the actual needs; second, whether the high-speed storage can achieve

There is also a third difficulty. This system is built on the basis of broadband and automation. When the system is running, it will generate a large amount of data, such as broadband original I / Q, narrowband I / Q, classification / identification demodulation / decoding results, broadband detection The result data, etc., how to dig out the communication rules of the network stations from these massive data, and obtain the interested station situation information is a major technical problem faced by the system.
