In this paper, a method of scanning and receiving two beams is theoretically studied. Two laser beams scanning respectively in the top half and the bottom half of the same frame, then separated at the two receivers. With the same imaging distance, the product of pixel and frame frequency can increase by two times; With the same product of pixel and frame frequency, the imaging distance without iuzziness can increase by two times. Therefore detecting two laser beams can increase the imaging performance for laser radar. Receiving the echo signal of two vertical polarized laser beams from the target is experimentally studied.
