| 摘 要： | 在水声环境中,由于发射和接收平台之间的相对运动,多普勒频移是无法避免的。提出了一种基于牛顿插值的回波多普勒频移仿真方法。该方法只用到相对径向速度,而不必知道发射脉冲的类型和频率参数,且具有仿真数据量小,精度较高的优点,可以很好地满足仿真系统逼真性和实时性的要求。该方法已用于研制成功的某型声纳仿真系统中,证明了该方法的正确性和有效性。 |

| 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 and 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 an... |
