Investigations on back scatter of typical projectiles for application of laser based trajectory measurement

摘要

The laser based trajectory measurement system referred to in a corresponding paper already gave theoretical considerations on the backscatter power of projectiles dependent on the angle of illumination by a laser. This leads to the question about the real angular backscattering properties of projectiles. Therefore, the need for an investigation of various projectiles is obvious. This paper presents back scatter examples for typical projectiles illuminated and viewed from defined angles. For each projectile its back scatter is recorded twice: once specially prepared with a Lambertian surface and once with its original surface. The results of the measurements provide an objective assessment for various camera arrangements of a LIDAR system. Finally, suitable camera configurations are shown.
