FIELD: sound fixing and ranging, detection of signals in aqueous medium. SUBSTANCE: signals are excited in hydroacoustic antenna displaying definite nonlinearity on frequency of its mechanical resonance by action on it with detected and additionally formed signals that satisfy condition Fr= Fadd± F, where Fr, Fadd, F are frequencies of mechanical resonance of antenna, additional and detected signals correspondingly. EFFECT: improved authenticity of method. 1 dwg
