With the wideband beamforming approaches, the synthetic aperture radar (SAR) could
achieve high azimuth resolution and wide swath. However, the performance of conventional …

Sparse microphone array design is receiving a great deal of attention, largely due to the
capacity to reduce the number of microphones. However, in general, using a sparse array …

Beamformer performs spatial filtering to preserve the desired signal while suppressing
interfering signals and noise arriving from directions other than the direction of interest …

This paper proposes a novel solution for separating an unknown and time-varying number
of moving acoustic sources in a blind setting using multiple microphone arrays. A standard …

Meeting or conference assistance is a popular application that typically requires compact
configurations of co-located audio and visual sensors. This paper proposes a novel solution …

This chapter is dedicated to the overview of the main results in the fields of adaptive
beamforming and robust adaptive beamforming. The basic principles and main approaches …

Audio-visual speaker tracking has drawn increasing attention over the past few years due to
its academic values and wide application. Audio and visual modalities can provide …

The performance of conventional adaptive broadband beamforming algorithms is degraded
because of rapidly moving interferences and look-direction errors. In this paper, a number of …

Sub-band adaptive processing is an established method to design a broadband
beamformer. The uniform decomposition method (UDM) is a common approach for …

In this paper, a new signal processing framework is proposed, in which the array time
samples are represented in DOA-frequency domain through a single stage problem. It is …
