A high-speed frequency band scanning method and equipment for a radio monitoring receiver

Abstract

The invention belongs to the technical field of radio monitoring receivers, and in particular relates to a high-speed frequency band scanning method and equipment for radio monitoring receivers: including a radio frequency module, a baseband module, and a host computer, wherein the baseband module includes A / D, DDC, Filter bank, FFT, data cache, radio frequency control module, frequency band scanning control module, USB interface; the baseband processing part is implemented in FPGA, while the upper computer control and data processing are implemented in ARM. The structure and technical proposal of the invention greatly improve the frequency band scanning speed of the radio monitoring receiver, so that the monitoring receiver can monitor the frequency hopping signal with high jumping speed. At the same time, it also has the following advantages: 1) The scanning speed is fast, and it is easy to monitor high-jump signals; 2) It supports low-speed mode, and can monitor conventional signals under the condition of ensuring spectrum accuracy; 3) The system structure is simple and easy for software The performance requirement of the hardware is low, and it is easy to implement.

Description

technical field [0001] The invention relates to the technical field of radio monitoring receivers, in particular to a high-speed frequency band scanning method and equipment for radio monitoring receivers. Background technique [0002] With the rapid growth of the national economy and the rapid development of the information society, the radio industry has shown explosive growth, which also makes the tense situation of radio frequency resources more severe, and puts forward higher requirements for my country's radio monitoring and management work. The current radio monitoring is mostly realized by the radio monitoring station, and the radio monitoring receiver is the core equipment in the monitoring station; [0003] At present, there are many types of radio monitoring receivers on the market, with different functions and performances, but common radio receivers have the problem of slow frequency band scanning; for ordinary signal monitoring, they can basically meet the moni...

Problems solved by technology

[0003] At present, there are many types of radio monitoring receivers on the market, with different functions and performances, but ordinary radio receivers have the problem of slow frequency band scanning; for ordinary signal monitoring, they can basically meet the monitoring requirements, but for frequency hopping with fast changing speed The monitoring of signals is far from meeting the monitoring requirements; in view of the importance of high-frequency scanning speed for the practical application of radio monitoring, it is more and more important to increase the scanning speed of frequency bands
