Problems solved by technology
[0004] This kind of radio spectrum monitoring station based on DDC system can change the central frequency and bandwidth, but it is not suitable for real-time monitoring and processing of parallel signals. It cannot completely cover signals in a wide frequency range, especially hopping and spread spectrum signals. It is used as The speed of search and monitoring is not fast enough, and signals will be missed or lost, resulting in missed alarms, and it is difficult to achieve full-probability signal interception of high-speed and broadband signals

Description
technical field [0001] The invention belongs to the field of radio and digital signal processing, and in particular relates to a broadband radio spectrum monitoring station applied to radio signal monitoring and spectrum management. Background technique [0002] Existing radio spectrum monitoring stations include receivers, signal processing units and antennas. In radio frequency spectrum monitoring, in addition to conventional fixed-frequency signal monitoring, it is also necessary to monitor and analyze high-speed, broadband signals, such as hopping and spread-spectrum radio signals. Since these radio stations adopt broadband real-time frequency hopping technology, These wire numbers have good anti-interference and anti-interception capabilities. Therefore, the monitoring and analysis of unknown broadband and burst high-speed signals has always been a hot research topic. [0003] After the traditional radio spectrum monitoring station passes through the antenna and recei...
