Abstract
The article deals with the distortion of high-frequency acoustic pulses with linear frequency modulation (LFM) in a hydroacoustic communication channel, which is caused by uneven frequency attenuation characteristics of the marine environment. The paper considers pulses with rectangular, sinusoidal and "raised cosine" type envelopes.
