N2 - Bearing-time-record (BTR) is widely used in sonar signal processing as an important display formats which may benefit the subsequent processing. The general way to get a BTR display is to parallel the outputs of the beamformer along time axis. This paper proposes a method to generate the BTR display which uses the L1 norm regularization and the total variation (TV) regularization to enhance the point-based feature and the region-based feature respectively. To improve the clutter suppressing ability, the two-dimensional total variation is used, utilizing the the temporal continuities of the sources. The BTR display generated by the conventional beamforming (CBF), L1 regularization, one-dimensional (1D) TV-L1 regularization and two-dimensional (2D) TV-L1 regularization are compared through numeric simulations.
