Abstract
Sonar emissions and the noises which corrupt them are pressure waves travelling in a four-dimensional space-time continuum. In the past, it has often been adequate to restrict consideration of such processes only to the time-domain signals emerging from the outputs of each of the hydrophones used for signal detection. Increasing computing power, together with a rapid evolution in appreciation of the mathematics of signal analysis and its application to particular physical problems must now lead the underwater acoustician towards a more all-embracing comprehension of the spatio- temporal nature of the processes he is called upon to handle.
