Abstract

A coherent lidar system based on a 3W cw CO₂ laser has been installed on an aircraft positioned to look forward and down. A monostatic optical geometry is employed and the optical system incorporates a scanning mechanism that generates a line scan in the horizontal plane perpendicular to the aircraft. This scan pattern, coupled with the aircraft motion, produces a 2D coverage of the ground. The laser reflections from terrain features are collected and 2D images of the ground generated based on the amplitude of the return signals. A flight program has been conducted and active images of a range of natural terrain and man made objects collected. This paper describes the coherent laser system, its aircraft installation, signal processing, and results obtained from the flight trial program.
