A new type Multi-Function Ionospheric Sounding System

This paper introduces a new type Multi-Function Ionospheric Sounding System (MFISS), which bases on the PXI bus. The capabilities of ionospheric vertical sounding, ionospheric oblique sounding and ionospheric oblique backscattering sounding were integrated in a single MFISS, it overcomes the disadvantages of the original ionospheric sounding equipments which have the feature with less function, limited coverage, less obtaining parameters, it also can achieve the function of acquiring the omnibearing geophysical characteristics, the ionosphere channel propagation characteristics and the radio environment characteristics. In this article, firstly, the system structure and the flow of signal processing were introduced, then some typical sounding results acquired by different detection modes were displayed. The sounding results indicate that the system is equipped to handle fast and has a high degree of software features, so for Engineering applications. it is of great significance for the development of ionospheric detection technology and the study of High Frequency(HF) channel characteristic.
