The method of visualizing the echo which is received by the active sonar which uses line spectrum discharge

摘要

As for this invention, it regards the method of visualizing the beneficial information which can by the operation of the active sonar which possesses line spectrum discharge, inside one picture. Depending upon this method, the operator, seeing simultaneously with the traces which are left the echo which needs supervision, sonar wave reverberation, the seabed, by the surface or cubic measure reverberation becomes possible. The aforementioned method, at least three stages, namely, especially fixing echo Doppler processing in order it discriminates to convert mobility echo (71) 1 stages of for the sake of and in the direction/distance aspect, formation of the artificial sonar picture which positions the echo which is detected (72) the step which includes the substitution of the artificial picture of the indication which is deduced from the reverberation from the bottom of step and the especially ocean (73) with it includes. The aforementioned method especially is ideal in the sonar system which uses the Doppler effect in order to characterize the echo which is received. Selective figure Figure 7
