Abstract

The invention relates to the technical field of automation identification, and provides an antenna system applied to three-dimensional scanning of a radar. The antenna system comprises antenna units, control switches, feed ports and a switch control system. The antenna units form an m*n antenna array. The control switches are arranged between the antenna units and used for being connected with the antenna units to form the m*n antenna array. The feed ports are connected with the antenna units at the tail ends of m rows and the tail ends of n lines. The switch control system controls the control switches to achieve two-dimensional scanning in the row direction and the line direction of an antenna beam. According to the antenna system, as the radio frequency switches are arranged between the antenna units, the switch control system controls the states of the radio frequency switches to achieve two-dimensional scanning in the row direction and the line direction of the antenna beam, and the three-dimensional scanning requirement of the radar is met.

Description

【Technical field】 [0001] The invention relates to the technical field of automatic identification, in particular to an antenna system applied to radar 3D scanning. 【Background technique】 [0002] The digital beamforming or phased array beam scanning performed by the existing radio frequency microwave band radar array antenna is usually a single-directional beam scanning in the vertical direction or the horizontal direction. If two-dimensional beam scanning in the vertical direction and horizontal direction is to be realized simultaneously to realize radar 3D scanning, the traditional method is a fully distributed phased array or digital array, which must be implemented by multiple independent T / R components or receiving components implemented in a phased array manner. The distributed phased array antenna requires each unit to be fed independently. When the antenna array is large in scale, the number of feed ports is extremely large, which increases the complexity of the sys...
