Title:
PHASED ARRAY DETECTION APPARATUS, LIDAR, AND SELF-DRIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/012088
Kind Code:
A1
Abstract:
A phased array detection apparatus (200), a lidar (300) and a self-driving device (500). The phased array detection apparatus (200) is used for calibrating a phased array transmission apparatus (100), and comprises: a detection unit (210), provided at an output end of the phased array transmission apparatus (100), and used for receiving a plurality of detection signals outputted by the phased array transmission apparatus (100) and converting the plurality of detection signals into electrical signals, the plurality of detection signals being a part of all optical signals transmitted by the phased array transmission apparatus (100); a signal processing unit (220), connected to the detection unit (210) and used for generating a control signal according to the electrical signals; and a drive circuit (230), connected to the signal processing unit (220) and the phased array transmission apparatus (100) and used for driving the phased array transmission apparatus (100) according to the control signal. The detection unit (210), the signal processing unit (220) and the drive circuit (230) work continuously until the phased array transmission apparatus (100) satisfies a preset initial state. The phased array detection apparatus (200) can calibrate a phased array without an external camera and manual modulation.
