9140 该方法首先把宽带干扰建模为多项式相位信号(polynomial phase signal,PPS),进而利用高阶模糊函数(high-order ambiguity function,HAF)以及相应的解模糊的方法来精确估计PPS的相关参数,从而将WBI信号转化为窄带干扰(narrowband interference,NBI)信号,然后利用现有的NBI信号抑制方法得到去除干扰后的回波信号; This method first put broadband jamming is modeled as a polynomial phase signal (polynomial phase signal, PPS), then using the high-order fuzzy function (high - order ambiguity function, HAF) as well as the corresponding solutions of the fuzzy method to estimate the related parameters of PPS and WBI signal can be converted to narrowband interference (narrowband interference, NBI) signal, and then using existing NBI suppression of method to remove interference signal, after the echo signal;
9141 最后,计算机仿真结果和实测数据处理结果验证了本文提出方法的有效性。 Finally, the computer simulation results and the measured data processing results show the effectiveness of the method proposed in this paper.
