Abstract:

Long Pulse modulator and power supply design problems were investigated and the effects of power supply regulation on the Long Pulse sideband distribution were considered. Development and testing of a PRF tracker and coherent transponder continued. The theory of spectral compression was modified and airborne equipment reworked for the second series of flight tests. Ranging techniques for the lunar landing requirement were considered and the most promising one selected for laboratory investigation. Optimum filtering studies and the development of a frequency tracker incorporating the results of optimum filtering studies continued. The 35 kmc receiver measurements were completed and promising results were obtained from the laboratory model of the 13.5 kmc parametric amplifier. Effort also continued on the wide dynamic range IF amplifier. The calculations on the effects of the plasma sheath on Doppler navigator operation were completed. Author
