Abstract
A method using a broadband transducer to measure the acoustic backscat ter cross section of suspended sand particles is investigated. The fre quencies used range from 1.3 to 2.8 MHz, and the sand sizes from 100- to 350-mum diameter. The measurements are made in the transducer near field. The measured form factor is compared with the theoretical resul t for the movable rigid sphere model, and with previous narrow-band me asurements.
