The ionospheric oblique backscattering sounding sys-tem can not only be used to detect the state of the ionosphere and the condition of high frequency channel in real time, but also be used for over-the-horizon sounding. Therefore, it has a very high military and civil value. For the characteristics of ionospheric oblique backscattering sounding, such as long sounding distance, wake echo, strong background noise, slow moving target, etc., a hardware platform of ionospheric oblique backscattering sounding system is designed. This platform adopts the technology of soft-ware radio and is designed as a new kind of general purpose, modularized, software-based ionosonde that is based on the VXI (Versa module eurocard eXtensions for Instrumentation) bus. This hardware platform has been successfully used in actual iono-spheric oblique backscattering sounding, and the experimental results demonstrate that this system can satisfy the requirements.
