【摘要】 相干多途信道的其冲激响应函数和频率响应函数只与收发位置及水文条件有关,与信号形式无关。本文从信道的冲激响应函数和频响出发,通过分析信道在不同条件下冲激响应函数的有效宽度、频响函数特征,得出一些有意义的启示,对水声信号处理有参考意义。更多还原

【Abstract】 The impulse response function and the frequency response function of the underwater acoustic channel are only in contact with the position of the sources and the receivers, velocity profile and depth of water, not with the form of the signals. Based on the channel’s impulse response function and frequency response function, some useful phenomena of signal procession have been drawn in view of the impulse response function’s available width and frequency response function.更多还原
