Abstract

This paper demonstrates an extremely low noise, phase-lockable microwave oscillator for next generation coherent radar applications. The design, built with commercially available hardware, is comprised of a high-Q sapphire loaded cavity feedback oscillator, a frequency locked loop for noise degeneration, a narrow band phase locked loop geared for noise measurement using the two-oscillator method and a servo loop for temperature stabilization.
