Middle ultraviolet spectra from 1800 to 3400A are analyzed. These spectra were obtained from the March 1990 rocket flight of the NPS MUSTANG instrument over the altitudes 105km to 315km. The data were compared with computer generated synthetic spectra. A least squares fitting procedure was developed for this purpose. Each data point was weighted using the standard deviation of the means. Synthetic spectra were generated for the following emissions: N2 Vegard-Kaplan; N2 Lyman-Birge-Hopf ield; NO y, 8, and e; 01 2912k, Oil 2470A; and Nil 2143A. Altitude profiles for the emissions were obtained. Tentative identification was made of the OIII 2853A emission. A comparison of VK and LBH profiles demonstrates the process of N2 A-state quenching by atomic oxygen.

Techniques and benefits of shaping the pulses of binary sequences with application to spread spectrum radio communications. Mavranganis, Panayiotis G. (Monterey, California. Naval Postgraduate School, 1979-03);This research is concerned with binary sequences. Such two-level voltage waveforms are used in some types of spread spectrum systems. Of interest in this work is the effect of shaping the normally rectangular pulses of ...
