Non-linear effects in a 200-kHz sound beam and the consequences for target-strength measurement

When estimating target strength (TS), sound pressure in the beam where the target is located has to be measured accurately. Sound pressure is normally calculated from the source level, and transmission loss is based on geometric spreading and absorption loss. Additional losses caused by non-linear a...
