Detection of point-like scatterers using one type of scattered elastic waves

In this paper, we are concerned with the detection of point-like obstacles using elastic waves. We show that one type of waves, either the [Formula: see text] or the [Formula: see text] scattered waves, is enough for localizing the points. We also show how the use of [Formula: see text] incident wav...

description In this paper, we are concerned with the detection of point-like obstacles using elastic waves. We show that one type of waves, either the [Formula: see text] or the [Formula: see text] scattered waves, is enough for localizing the points. We also show how the use of [Formula: see text] incident waves gives better resolution than the [Formula: see text] waves. These affirmations are demonstrated by several numerical examples using a MUSIC type algorithm.
