  Abstract: Target echo strength (TES) measurements of the smaller M32T and M32C TESSMEX models (1.5 m length) were taken at the NPL underwater acoustic test and calibration facility at Wraysbury, Windsor, UK. The facility is a floating laboratory accessed by boat, situated on a freshwater reservoir constructed as a concrete bowl with mud bottom. Water depth varies from 15 - 20 m over the year.\n\nWe present time-series and frequency-aspect (FRAS) data covering frequency ranges between 1 kHz and 60 kHz. Wideband representations of the data simultaneously reveal geometric object features at higher frequencies, as well as the elastic response and late arrivals at lower frequencies. Further processing of the data provides additional insights into the acoustic response of the objects.\n\nAdditionally, we present TES measurements of autonomous underwater vehicles (AUV) and remotely operated vehicles (ROV) such as the REMUS 600 and VideoRay Defender, illustrating the flexibility and versatility of the measurement system.
