Abstract
In the reflection point search using rectangular sound sources, a rectangular transducer array with small number of element was introduced, and the improvement on the search result was attempted. Results of numerical calculations show that there is the position where the search result is improved. However, the position where the search result is not improved also exists. In order to attempt the improvement on the search results, it is necessary to conduct further examinations with respect to the conditions of the reflection point and sound sources.
