Time-reversal music imaging using a recursive approach

The time-reversal imaging with multiple signal classification (MUSIC) method for the location of point targets was first proposed by Devaney et al. In this contribution, a recursive time-reversal MUSIC algorithm is proposed in order to improve the detection and the location of close targets. The considered approach is based on the recursively applied and projected (RAP) MUSIC method which was first introduced for magnetoencephalographic (MEG) data processing.
