The performance predictions for sonar assume a background of Gaussian noise, however, deviation from this assumption may generate false alarms. This paper attempts to find out whether the ambient noise in tropical waters of the western coast of Indian continental is Gaussian. Gaussianity is tested using graphical, numerical and verified using formal normality tests like Kolmogorov Smirnov (KS) test and Lilliefors (LF) test. Ambient noise recorded at 30 m of depth using passive sonar is found… CONTINUE READING
