ABSTRACT:
The invention relates to a method for the visualisation in a single image of the useful information obtained by the operation of an active sonar with line spectrum emission. The method permits an operator to simultaneously view the echoes which may need monitoring and the trace left by the sonar wave reverberation, seabed, surface or volume reverberation. Said method comprises at least three phases: one phase for Doppler processing (71) particularly for differentiation of the fixed echoes from mobile echoes, a step for generation (72) of an artificial sonar image positioning the detected echoes in a direction/distance plane, a step (73) comprising the replacement in the artificial image of a representation derived from the reverberation, in particular of that from the marine bed. Said method is particularly suitable for sonar systems using the Doppler effect to characterise the received echoes.
