Abstract

A system has been developed for calibrating and precisely pointing a germanium dual-wedge scanner for a CO2 Doppler lidar from an airborne platform. This paper describes equations implemented in pointing the scanner as well as those in the iterative calibration program, which combines available data with estimated parameters of the scanner orientation relative to the axes of the aircraft's inertial navigation system to arrive at corrected scanner parameters. In addition, this paper investigates the effect of specific error conditions on program performance and the results of the program when used on 1981 flight test data.
