摘要
Abstract
In underwater acoustic environment, Doppler frequency shift is unavoidable because of relative moving between transmitter and receiver. The proposed method based on Newton interpolation is effectively applied to simulation of target echo Doppler frequency shift. This method only uses the relative radial velocity and is needless to know the type arid frequency of transmission pulse. In addition, it has the advantages of small amount of simulation data and high precision, can satisfy the requirements of real-time and reallty in simulation system. It has been applied in a developed sonar simulation system. The results show the correctness and validity of the method.关键词
