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.

Abstract: Example control methods and apparatuses, example LiDARs, and example terminal devices are provided. One example method includes controlling a transmitter to transmit a first pulse train, where the first pulse train includes M1 first-type pulses and M2 second-type pulses, M1 is an integer greater than 1, and M2 is a positive integer. The transmitter is controlled to transmit a second pulse train, where the second pulse train includes at least one of M3 first-type pulses or Ma second-type pulses, where a power of a first-type pulse is greater than a power of a second-type pulse, and where the second pulse train and the first pulse train have different transmission time periods, or correspond to different sub-emitters, or correspond to different pixels in a detection field of view, or correspond to different detection fields of view, or correspond to different sub-receivers.

Abstract: This application is applied to the autonomous driving field, and provides a signal receiving apparatus, a detection apparatus, and a signal processing method and apparatus. The receiving apparatus includes a first receiving branch; the first receiving branch includes a first detector and a signal coupling apparatus; the first detector is configured to output one branch of echo electrical signal; the signal coupling apparatus outputs at least two branches of echo electrical signals based on the branch of echo electrical signal output by the first detector; and one branch of echo electrical signal in the at least two branches of echo electrical signals has same signal strength as the branch of echo electrical signal output by the first detector.
