Measurement and simulation on laser scattering properties of the complex target

Abstract

The laser scattering properties of the target, which is characterized by the laser radar cross section (LRCS), are the theoretical basis of the target detection and recognition of a lidar system, and play an important role in the design and evaluation of a lidar system. We calculated the LRCS of the vehicle based on the in-field measurement and numerical simulation. The experimental results demonstrate that the trend of simulated data of the vehicle and the corresponding experimental data is qualitatively similar, but there is a big difference in absolute value. Based on this, we can optimize the approaches for researching the laser scattering properties of the target.
