OPTICAL PHASED ARRAY-BASED LASER RADAR TRANSCEIVER ANTENNA AND DISTANCE MEASUREMENT METHOD

An optical phased array-based laser radar transceiver antenna and a distance measurement method; the optical phased array-based laser radar transceiver antenna comprises a distance measurement module (17) based on a single-point transceiver, a signal processing module (7), a central controller (20) and a laser driving module (2); the laser driving module (2) and the signal processing module (7) are both connected to the central controller (20). The distance measurement module (17) comprises a single-point transmitting unit (50) and a single-point receiving unit (60); the laser driving module (2) drives the single-point transmitting unit (50) to emit a light beam, and controls the light signal transmission direction of the light beam; the single-point receiving unit (60) receives the light signal reflected by a detected object and transmits same to the signal processing module (7) for processing so as to calculate the displacement of the detected object. The single-point transmitting unit (50) and the single-p
