The invention provides a laser radar. The laser radar comprises a laser emitting module, a light division module, a scanning module and a receiving module; the laser emitting module is used for emitting pulsed laser beams; the light division module is used for dividing the pulsed laser beams into N incident beams and transmitting the incident beams to the scanning module, wherein N is larger thanor equal to 2; the scanning module is used for reflecting the N incident beams to a three-dimensional space and receiving and reflecting N echo beams, reflected by a to-be-tested target in the three-dimensional space, of the N incident beams; the receiving module is used for receiving and processing the N echo beams; the light division module and the scanning module correspondingly form N subsidiary scanning view fields, and the N subsidiary scanning view fields constitute a total view field of the laser radar through view field splicing. By means of the laser radar, the light division moduleis utilized, light sources simply with the number smaller than N can be adopted on the premise of satisfying a scanning view field of the laser radar, the cost of the laser radar is lowered, the heatgenerated inside is reduced, and the size of the laser radar is reduced.
