Abstract

In the design process of Laser radar applications the scatter cross section of small objects like bullets is a basic problem. An estimation of detection rates depends strongly on the amount of light power reflected to the receiver as well as on the deliverable information about the objects geometry. Since very little information on Lidar cross sections of basic geometries in question is available - except for some exemplary experimental data - typical body shapes have been investigated. For simplicity, the two main cases, perfectly reflecting surfaces and Lambertian surfaces, are treated analytically, so a real body with direct and diffuse reflection in arbitrary weighting can be modeled. As a result, the amount of power reflected to the receiver as well as the actual image of the object gathered by an imaging device can be predicted. A mathematical estimation framework for the treatment of arbitrary bodies is developed, based on analytical and numerical methods and a set of basic cases, resulting in several rules of thumb. Besides the theoretical part, some illustrating experimental results are given..
