Description
A study of the impulse response of the acoustic channel in shallow
waters is presented with respect to space, time, and frequency shift over a
time window of two hours. A broadband chirp (42–54 kHz) and a narrow
band sine wave (58 kHz) are transmitted from a static source located at 51 and
166 m from a vertical line receiver array. In 20 m of water with 0.4 m of wave
height, an average Doppler shift of 20 Hz is measured at 51 m range, and 10
Hz at 166 m range, due to the sea-surface motion.
