The invention discloses an ultra-wideband spectrum monitoring system and method, and the system comprises a signal filtering processing module which is used for receiving a first frequency band signal, carrying out the filtering processing of the first frequency band signal, transmitting the first frequency band signal to a zero intermediate frequency signal processing module, receiving a second frequency band signal, and transmitting the second frequency band signal to a radio frequency direct collection module; a zero intermediate frequency signal processing module which is used for amplifying, filtering and down-converting the received first frequency band signal into a zero intermediate frequency signal, and outputting a digital signal to the digital signal processing module after analog-to-digital conversion; a radio frequency direct acquisition module which is used for performing analog-to-digital conversion on the received second frequency band signal and outputting a digital signal to the digital signal processing module; and a digital signal processing module which is used for carrying out frequency spectrum monitoring on the digital signals received from the zero intermediate frequency signal processing module and the radio frequency direct acquisition module. According to the invention, the zero intermediate frequency signal processing technology and the radio frequency direct acquisition technology are combined to replace the traditional signal receiving and transmitting circuit built by using separated components, so the board distribution area and the board distribution difficulty are reduced.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to an ultra-wideband spectrum monitoring system and method. Background technique [0002] Due to the development and application of radio technology, spectrum resources are increasingly tight, and the electromagnetic environment is becoming more and more complex. In order to effectively use spectrum resources, avoid mutual interference of various equipment, and ensure the normal operation of various communication equipment, ultra-wideband communication has gradually attracted people's attention. Ultra-wideband communication is also of great value in military and public security, and can cooperate with public security and military The department monitors relevant objects and efficiently collects relevant information, especially in the military. Due to the high spectrum utilization rate and strong anti-interference ability of ultra-wideband transceivers, it can reduce t...
