According to the need of laser measurement system design and evaluation, the related problems such as the calculation method and application of target Lidar section (LRCS) are studied. On the basis of discussing the general LRCS calculation method, aiming at the specular reflection target, a simple LRCS engineering estimation method is proposed and applied to the laser angle reflector target and cat’s eye target. The corresponding LRCS estimation formula is obtained. From LRCS from the perspective of the target derived laser measurement equation, the equation can be widely applied to various types of laser measurement systems and a variety of scattering characteristics of the target, and has the characteristics of simple and convenient application, can be widely used in various types of laser measurement system demonstration design and Performance evaluation.
