Download or read book Conceptual Design and Analysis of an Infrared Horizon Sensor with Compensation for Atmospheric Variability written by Antony Jalink and published by . This book was released on 1972 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A horizon detection logic, based on a ratio-of-integrated-radiance concept, which detects the earth's horizon at a relatively stable height under all geographic and meteorological conditions was evaluated by computer simulation on a body of synthesized radiance profiles. An error-sensitivity analysis of the concept was performed, and optimum design parameter values for a sensor were determined. A conceptual design for an improved 15 micron sensor based on this analysis is discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Radiance measurements of the Earth's horizon in three infrared spectral regions were made during two Aerobee rocket flights at White Sands Missile Range, New Mexico. Preliminary results indicate equivalent blackbody radiation temperatures in the CO2 band (14.0 - 15.6 microns) varied from 231K to 239K; in the atmospheric window region (10.2 - 11.8 microns) from 205K to 287K; and in the rotational water vapor band (19.5 - 31.8 microns) from 206K to 239K. Numerous dropouts due to clouds are apparent in the atmospheric window and water vapor bands, while no such effect is evident in the CO2 band. The infrared radiometer, stellar aspect sensor and vehicle attitude control system are described, and actual traces of the horizon profiles and outputs from the stellar aspect system are included.

Available in PDF, EPUB and Kindle. Book excerpt: An analysis has been made of atmospheric radiance data which were computed by the Weather Bureau based on a variety of atmospheric models. Narrow spectral regions, located within the carbon dioxide absorption band centered at 15 microns, have been considered. It is shown that a spectral band approximately 1.7 microns wide centered very close to the absorption band shows promise, when the data is properly processed, of providing 1 Sigma horizon sensor accuracies of about 0.05 degrees. A 'two color' technique involving the use of two spectral regions in the vicinity of the CO2 absorption band is discussed. The possibility of using the 28.6 to 40.0 micron spectral region within the broad rotational water vapor absorption band is also considered. (Author).
