Abstract
A method of estimating scatterer concentration near a concentration gradient using the data of a single received waveform is reported. It is shown theoretically that for random scatterers obeying the Born approximation the volume density near a boundary is proportional to the square of the ratio of the amplitude of the boundary echo whose magnitude spectrum is normalized, to the echo standard deviation from inside the scatterer medium. In the case that the scattering signal from the boundary displays strong coherency, normalization is not required. The theory is shown to be confirmed by experiment for cases in which the above ratio is much larger than unity.
