Extension of the Target Strength Studies
Abstract
The first and most important conclusion that can be made from this investigation is that the method used is essentially valid, that realistic echoes can be formed, and that target strengths can be accurately predicted if the proper choice of parameters can be made. Secondly, it can be seen from the figures that the sail plays a significant part in echo formation and is the dominant influence on target strength. This can also be seen on typical echoes by comparing echo maxima with corresponding position on the submarine. The third conclusion to be made is that it can be seen that the effects of acoustic absorbers can be large or small, depending on how they are used. When a better geometrical description of the submarine is available, an efficient distribution of acoustic absorbers may be found by exercising the program with different placements of the coating. It is likely that significant reductions in target strength can be made by the proper use of acoustic absorber coatings.
