Abstract: The self-weight of a large fully-steerable radio telescope is one of the important factors affecting its performance. In the existing reflector system scheme, the problem of surface accuracy caused by its large and heavy structure… read more here.

Abstract: Both the null-constrained method and the Jacobi-Anger expansion method are commonly adopted to design the fully steerable circular differential microphone arrays (CDMAs). So far, these two methods have been independently studied, and it is unclear… read more here.

DOI: 10.1109/taes.2025.3595823
Abstract: Conventional differential directivity algorithms are highly dependent on array configuration, especially when designing steerable differential beamformers. To this end, we proposed a method for designing a fully steerable directional differential beamformer based on an acoustic… read more here.

DOI: 10.1109/tim.2025.3568979
Abstract: Differential line arrays (DLAs) hold significant potential for practical signal enhancement, but DLAs are not capable of realizing the Nth-order fully steerable function. To overcome this problem, this article introduces a novel fully steerable differential… read more here.
