基于I/Q数据采集的便携式无线电检测终端OA北大核心CSTPCD

In order to further improve the efficiency of electromagnetic spectrum detection and the capability of measurement data processing,a portable electromagnetic spectrum detection equipment is designed,and a data processing system is proposed.During the measurement,the electromagnetic spectrum detection equipment can display the number of acquisition frames,acquisition frequency band,energy value,I/Q distance,etc.in real time.By deploying the signal detection algorithm in the system,the equipment can also find and mark signals from the collected frequency band in real time,and distinguish the noisy signal from the effective signal.At the end of the measurement,the system can visualize the collected data immediately in the device,and get the basic features of the collected electromagnetic spectrum signals.In order to ensure data security and stable operation of the portable device,a data transmission system is added to the system,so that the measurement data and processing results can be uploaded automatically to the server for the storage.The data transmission system can enable the device to clean up local data in a timely manner,release the storage space of the local device,and enhance the robustness of the device.The feasibility and data processing effect of the designed equipment and system are verified by examples,which can provide a new direction for electromagnetic spectrum detection and data processing.
