摘　　要：理论分析了短波信道散射函数的计算,给出了实际短波信道探测中散射函数的测量方法,以及利用散射函数估计短波信道的衰落带宽、衰落相干时间、多径散布、相关带宽和信号的多普勒频移、传播时延等参数的方法。从实验数据中得到了短波信道的散射函数,利用散射函数估计了上述参数,给出了估计结果。The calculation of scattering function of high frequency channel was analyzed theoretically and the measure method of scattering function in high frequency channel sounding experiment was provided. Then the estimation methods of the parameters such as fading bandwidth, fading correlation time, multi - path disperse, correlation bandwidth of high frequency channel and the Doppler shift, delay time of high frequency signal by scattering function were given. The scattering function of high frequency channel was obtained from experiment data and the parameters related above were estimated by it. At the same time, parameters estimation results were provided.
