FEATURES OF DISTRIBUTION AND INTERFERENCE OF NORMAL WAVES IN THE WAVEGUIDE SYSTEM THE WATER LAYER - THE SEABED WITH LOW SHIFT ELASTICITY
Calculation of complex roots of the dispersive equation for normal waves in a type wave guide a water layer - a firm half-space of sedimentary type for a case when the speed of a shift wave in a half-space is less than acoustic speed in a water layer is executed. Calculations of dispersive dependences for phase and group speeds and coefficients of attenuation of normal waves of various order are executed. Special attention is paid to the interfaced couple of normal waves of a zero order which in limit cases of low or high frequencies degenerate in a boundary wave of Rayleigh or in boundary waves of Rayleigh-Sholte, regular and generalized, respectively. Options of implementation of boundary waves of Rayleigh-Sholte in the interferential structures registered by the combined receiver in regular and irregular wave guides are considered.
