Problems of Spatial Signal Processing in Shallow Waterrview over several earlier publications of the author a number of unpublished results are presented. In conclusion, the dispersive channel offers additional possibilities of passive position finding, if the channel parameters are known and the fluctuations are small. Otherwise, the dispersive field

Sampling Theory and Wave Propagationrequency-band processing methods, involving multichannel interferometric methods in adjacent narrow frequency bands..Such methods involve a time-frequency representation of the seismic trace, in other words “Instantaneous Frequency Spectra”..In this paper, we describe a practical 2D time-frequency s

ructure can be accurately localized as a retroperitoneal tumor by observing displacement of the kidney, particularly if the kidney is pushed caudally and medially, superi­ orly and laterally, or medially. Anomalies of the kidneys include abnormal position, abnormal number, changes in shape, and alte
