Generating an Error Analysis for an Airborne Radiometric System
A. J. Verderese · Optical Engineering · 1976
This paper presents an error analysis for an airborne radiometric system. The system under scrutiny is a scanning radiometer operating at two wavelengths in either a warm or cold mode. Each wavelength channel consists of an array of N detectors. The long wavelength channel is used for display purposes (acquisition, tracking), whereas both channels are used for data reduction purposes. The data are recorded on analog and digital tapes (both sensor as well as general housekeeping data), reformatted and made ready to undergo stan-dard Fortran type operations. The sensor data consist primarily of target voltage waveforms interspersed among erroneous voltage pulses and white noise. It is desired to ascertain the peak values of the target voltage pulses and relate these peak values to target irradiances via the a priori laboratory calibration. Hence, it is observed that the errors can be classified as belonging to one of the following subsystems: 1) Calibration 2)The sensor itself 3) Data processing and reduction
