DOPPLER SPLITTING OF AN EMISSION-LINE PRODUCED BY AN OSCILLATOR MOVING OVER AN ICE COVER

Doppler effect was studied for a point oscillator uniformly moving ove r a floating ice layer. A relation for the ice displacement was obtain ed that allowed the calculation of the time and space spectra of the w ave field. It was demonstrated that the line could split due to the si multaneous occurrence of the normal and anomalous Doppler effects. Con ditions were determined under which the line splitting is caused by th e complex aberration effect.
