Abstract

The embodiments of the invention disclose a phased array radar and a phased array radar control mode. The phased array radar comprises multiple waveguide tubes, wherein each waveguide tube comprises multiple linear portions and multiple arc portions, in each waveguide tube, the linear portions are connected with another linear portion though the arc portions, the center lines of the arc portions are superposed with the center lines of the corresponding linear portions of an adjacent waveguide tube, and the multiple linear portions of the multiple waveguide tubes are parallel to one another; multiple antenna emitters which are arranged on each linear portion of each waveguide tube; multiple phase shifters, wherein each phase shifter is corresponding to one waveguide tube and is connected with the corresponding waveguide tube; and a metal line which is successively connected with the multiple phase shifters. According to the embodiments of the invention, the scanning efficiency can be improved.

Description

technical field [0001] The invention relates to the field of laser radar, in particular to a phased array radar and a control method for the phased array radar. Background technique [0002] Lidar is a system that emits laser beams to detect characteristic quantities such as the position and speed of targets, and is widely used in the field of laser detection. In order to be suitable for 2D and / or 3D detection, the laser beam emitted by the lidar needs to be rotated. In order to achieve the rotation of the laser beam emitted by the lidar, there are two ways. One is to use a mechanical device to rotate the lidar itself, and the second is to keep the lidar itself stationary or relatively stationary, and only change the beam emitted by the lidar. A phased array radar is a radar that is static or relatively static, and only the emitted beam changes. [0003] Phased array radar usually includes: laser transmitting and receiving arrays, used to transmit and receive multiple las...
