Antenna array, antenna transceiver system and radar system

Abstract

An embodiment of the present application discloses an antenna array, comprising N antenna elements; the N antenna elements have the same wavefront direction and the transverse spacing between every two is equal. The feeding phases of the N antenna elements form a first arithmetic sequence, and the tolerance of the first arithmetic sequence is a preset phase difference; The distances of the N antenna elements to the vertical plane in the wavefront direction form a second arithmetic sequence, and the tolerance of the second arithmetic sequence is a preset distance difference; The spatial phase difference between the N antenna elements formed by the preset distance difference and the preset phase difference is cancelled out with respect to the vertical plane; 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, the leakage signal can be canceled, the self-jamming is greatly reduced, the receiving channel of the radar system is protected, and the sensitivity of the radar system is improved. Embodiments of the present application also provide an antenna transceiver 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...
