面向频谱数据库的电磁频谱检测系统

Electromagnetic frequency spectrum detection system based on frequency spectrum database

频谱数据包含无线电信号的全息特征,针对频谱数据结构复杂、数据量大且利用率低的问题,提出一种基于频谱数据库的电磁信号检测系统。在实现通用的频谱检测功能的前提下,将频谱数据实时地保存到数据库中,用于后期有效信息的提取和分析。系统使用上位机向主控模块发送频谱检测的指令,由主控模块驱动信号采集模块进行数据采集并将其存储到数据库中。实例验证了系统的可行性以及数据的准确性,为实现对有限频谱资源的高效利用提供了一种新思路。

In allusion to the problems of complex structure,large data quantity and low utilization rate of frequency spectrum data which contains the holographic characteristic of radio signals,a electromagnetic signal detection system based on the frequency spectrum database is proposed. The frequency spectrum data is stored in the database in real time on the premise of realizing the common frequency spectrum detection function,which is used for extraction and analysis of effective information in the later stage. In the system,the upper computer is used to send the frequency spectrum detection instructions to the master control module. The master control module drives the signal acquisition module to collect data and store it in the database. The examples verified the feasibility of the system and the accuracy of the data,which can provide a new idea for high-efficient use of limited frequency spectrum resources.
