Problems solved by technology

[0003] However, since the MIMO antenna is essentially a multi-antenna technology, it inevitably has the problem that the antenna occupies a large area
Excessive antenna area compresses the available space for other circuit components and increases antenna manufacturing cost

Abstract

A millimeter wave MIMO radar antenna and a control method thereof. The present invention includes multiple sets of transmitting antennas and multiple receiving antennas arranged in two rows in sequence, wherein each transmitting antenna and each receiving antenna includes 6 dipole units connected by a feeder line and one of the dipole units connected by a feeder line impedance matcher. When each transmitting antenna in the above antennas transmits an electromagnetic wave signal according to the driving signal, it can be equivalent to transmitting the same electromagnetic wave signal at the position of the transmitting antenna that transmits the electromagnetic wave signal , and each equivalent transmitting antenna corresponds to several equivalent receiving antennas. Therefore, the present invention utilizes the equivalence of antennas to double the number of receiving antennas in a smaller size, improve the system's angle measurement accuracy, clutter suppression ratio and other performance indicators, without increasing the antenna transmission power and area. Under the circumstances, the matching of the signal quality is equivalently doubled.

Description

technical field [0001] The invention relates to the technical field of microwave communication, in particular to a millimeter-wave MIMO radar antenna and a control method thereof. Background technique [0002] MIMO (Multiple-Input Multiple-Output) technology refers to the use of multiple transmitting antennas and receiving antennas at the transmitting end and receiving end, respectively, so that signals are transmitted and received through multiple antennas at the transmitting end and receiving end, thereby improving signal quality. It can make full use of space resources, realize multiple transmissions and multiple receptions through multiple antennas, and can double the signal quality without increasing the transmission power of the antennas. [0003] However, since the MIMO antenna is essentially a multi-antenna technology, it inevitably has the problem of a large occupied area of ​​the antenna. An overly large antenna area compresses the available space for other circui...
