Laser radar

The utility model relates to a laser radar, and belongs to the technical field of radar systems. The laser radar comprises a housing and a plurality of measuring systems. The machine shell is provided with a window, the plurality of measuring systems are all located in the machine shell, and a receiving and transmitting light path of each measuring system corresponds to the window; the multiple measurement systems are sequentially arranged in the direction corresponding to the window, the heights of the multiple measurement systems are sequentially increased from the direction close to the window to the direction away from the window, and the total vertical field angle formed by splicing the vertical field angles of the multiple measurement systems is larger than the vertical field angle of any measurement system. And the sum is less than or equal to the sum of the vertical field angles of all the measurement systems. According to the invention, the vertical field angle of the laser radar in the vertical dire
