摘要
Abstract
Radio frequency(RF)direct acquisition technology has been widely applied in radar,communication,electronic warfare,especially in the field of integrated receiver.However,the extremely high sampling rate of RF data leads to greater difficulty in subsequent signal transmission and real-time processing.Digital resampling technology can reduce the sampling rate in the digital domain,thereby alleviating the signal processing pressure caused by RF direct sampling.In this paper,the digital resampling technology is studied,and a resampling method combining integer extrac-tion with decimal interpolation is proposed.The theoretical model is derived,and the corresponding parameter recur-rence solution method is presented.The simulation verifies the effectiveness of the method.The proposed method can not only reduce the pressure of real-time digital signal processing caused by direct decimal interpolation at high sam-pling rates in radio frequency,but also meet the need of precise variable sampling rate processing in special scenarios while ensuring signal quality,thus achieving large-scale and arbitrary fractional extraction.关键词
