Abstract: A signal processing method includes: obtaining a first detection signal corresponding to a first detection region, where the first detection signal includes a noise signal of the first detection region; and outputting indication information based on the first detection signal, where the indication information indicates that interference exists in the first detection region. According to the method, a proactive alarm function is implemented. The indication information indicates interference such that an alarm can be reported in time when interference occurs.

Abstract: An antenna unit and an antenna array. The antenna unit includes M layers of cross metal patches, M layers of dielectric substrates, and a metal ground layer, where M is an integer greater than 1. In addition, an ith-layer dielectric substrate is disposed between an ith-layer cross metal patch and an (i+1)th-layer cross metal patch. The ith-layer cross metal patch, the ith-layer dielectric substrate, and the (i+1)th-layer cross metal patch are sequentially stacked, and i is an integer ranging from 1 to M−1. An Mth-layer cross metal patch, an Mth-layer dielectric substrate, and the metal ground layer are sequentially stacked. The antenna unit and the antenna array formed by units may have a good polarization feature, a relatively wide operating bandwidth, and a relatively good phase shift feature.
