A set of data acquisition and processing software system has been designed and implemented, based on the newly-developed ionospheric sounding hardware platform. The software system introduces many advanced programming techniques such as multi-threaded, driver development and the ring buffer, etc. At the same time, it adopts some digital signal processing algorithms like FFT and RFIM so as to improve the signal noise ratio of the system. The applications of these technologies ensure the best system performances in high-speed, high efficiency, high stability and reliability. The experimental results on the spot reveal that the software is stable, reliable, and the acquired data is accurate and usable, therefore, it can satisfy the demands for ionospheric sounding.
