Paper Abstract

In scanning laser radar systems, the question of trade off between coverage rate and other system parameters like detection probability often arises. This is especially true for pulsed systems , as the risk of missing the target is greater than for CW-systems. Beam shaping e.g. in the form of a fan beam 1 is a convenient way of reducing the scan rate while still maintaining a high frame rate and a wide field of view. In this case a linear detector array matches the beam footprint. For extended targets the coverage rate and the angular resolution often dictates the beam size. For point targets the coverage rate and the detection probability and false alarm rates are driving the beam choice. This paper will discuss how the choice of beam size and shape as well as scan rate will affect the performance of a scanning coherent laser radar looking for point targets. Different target signal statistics and atmospheric effects are taken into account.
