介绍电离层斜向返回探测系统中PC与DSP板的通信方法，包括PC向DSP板装载程序、从DSP板读取数据、与DSP参数的传递机制。该方案保证了探测过程的连续性，提高了探测数据处理结果的有效性。

This paper introduced one kind of communication method between PC and DSP in ionospheric Oblique backscattering sounding system(IOBSS), which is composed of three parts: PC sending executable code to DSP, PC reading data from DSP and the parameter exchange between PC and DSP. This method ensured the consecution of the sounding process and enhanced the efficiency of the processing result of the sounding data.
