Influence of the echo shapes on the result of tomographic image

摘要

The paper studied the effect of the error on the form of echo location calculation reflector. Various options for reducing the duration of the echo and received at the same artifacts, which is caused by the inability to determine the temporal position of the start of the echo. To reduce the error to use the autocorrelation function offers instead echo, and its autocorrelation function in the reconstruction of a tomographic image.
