Research on building signal processing analysis module using RTL-SDR

Tóm tắt

The research focuses on the development and evaluation of a radio signal processing and analysis module, utilizing RTL-SDR equipment in combination with a Raspberry Pi 4 Model B embedded computer. By applying signal processing algorithms such as the Fast Fourier Transform (FFT), FIR/IIR filters, and CFAR detection techniques, the software was tested using signal data captured across various frequency bands. The results demonstrate that the system is capable of detecting real signals with high speed and accuracy. Based on these findings, the study proposes solutions to enhance the application, including improving sensitivity and processing speed, integrating artificial intelligence to analyze complex signals, implementing remote control capabilities, and expanding the system's practical applications in both civilian frequency monitoring and military operations.
