Abstract

Alcatel Space Industries has acquired a wide experience in the development of optical payloads for space application. The increasing demand in terms of ground sampling distance, swath width and number of spectral bands leads to high and critical detector frequency ranges. The data rate at detector video output may increase to values which are not compatible with the required radiometric performances. The present paper describes the figure of merits which allow to express the performances of CCD video signal and their relations with detector and optical payload radiometric performances. Improving CCD video signal performances is performed through the optimization of CCD operating conditions: sequencing and phasing between critical clocks, clocks rise and fall slopes, clock high and low levels and detector biasing. Even if closely related to the application, a methodology for optimizing the video signal is proposed. This methodology is applied on a video signal for operation up to 10Mpixels/second on several detector outputs, and the video signal performance improvements are described for each step of the optimization process, starting from the operating conditions provided by the detector manufacturers. The final improvements are presented and conclusions on the acceptability of the CCD performances are given.
