    Abstract: The Open Water Testing Facility at Wraysbury, UK has been used for low-frequency wideband target echo strength (TES) measurements over the past several years. The facility is located in a freshwater reservoir with a natural clay and silt bottom, and water depth varying from 15 to 20 m over the year. Measurements are made using a suspended transducer array, with the object also suspended and continuously rotating. Data is acquired over a frequency range from a few kHz up to about 100 kHz at regular intervals of 0.5 deg over one or more complete rotations. These data are acquired within 30 to 60 min per object. TES measurements of a benchmark cylindrical shell will be shown and compared against finite element modelling results.
