Abstract

The embodiment of the present application discloses an antenna array, including: N antenna units; the wavefront direction of the N antenna units is the same and the lateral spacing between any two is equal; the feeding phase of the N antenna units forms a first arithmetic sequence , the tolerance of the first arithmetic sequence is the preset phase difference; the distance from N antenna elements to the vertical plane in the wavefront direction forms the second arithmetic sequence, and the tolerance of the second arithmetic sequence is the preset distance difference; the preset distance The spatial phase difference between the N antenna elements formed by the difference with respect to the vertical plane cancels the preset phase difference; N is an integer greater than or equal to 2. When the antenna array is applied to the transmitting and receiving channels of the radar system, it can cancel the leakage signal, thereby greatly reducing self-interference, protecting the receiving channel of the radar system, and improving the sensitivity of the radar system. The embodiment of the present application also provides an antenna transceiving system and a radar system.

Description

technical field [0001] The present application relates to the technical field of radar, in particular to an antenna array, an antenna transceiving system and a radar system. Background technique [0002] With the continuous development of science and technology, there are more and more types of electronic products on the market. In addition to traditional personal computers and mobile terminals, emerging electronic products such as virtual reality devices have also appeared. For users, they often have multiple electronic devices, and often need to use multiple electronic devices at the same time. At this time, traditional human-computer interaction methods require users to use human-computer interaction devices installed on different electronic devices. It greatly affects the user experience and reduces work efficiency. Therefore, users urgently need a revolutionary human-computer interaction device, so that users can realize character input and various control functions wi...
