摘要

    摘要
  • 摘要: 基于简正波声场理论,导出了声源和接收器运动情况下窄带脉冲声传播的表式。分析了窄带脉冲声的单个简正波Doppler频移特性。通过研究接收与发射脉冲信号的相关,给出了窄带脉冲信号的Doppler匹配条件以及Doppler频移补偿间隔的一般表式。浅海55 km的D0ppler频移补偿实验验证了理论结果。
    Abstract: A representation of impulsive sound propagation with the moving source and receiver in ocean waveguides is derived based on the normal mode theory. The Doppler frequency shift of individual normal mode of narrow-band pulse is analyzed. By studying the correlation between emitted and received signals, the Doppler matched condition and the Doppler compensation interval are obtained. An experiment of long-range impulse propagation at 55 km in shallow water is to verify for testing the theoretical results of the Doppler shift compensation.
