A Phase Correction System for Radar Transmitting Tubes.
Abstract
A phase correction system for wide-band high-powered transmitting tubes is described. This system consists of a phase modulator inserted ahead of the transmitting tube and a phase detector connected with a small coupling coefficient to the output, and with a reference signal obtained through a parallel constant time delay path equal to the average value of the delay through the tube. The phase detector output is then amplified and used to drive the phase modulator so as to approximately cancel the nonconstant time delay characteristics of the tube. Such a system should eliminate the need for a transversal equalizer. A model transmitting tube was constructed and experimental tests are shown to prove the validity of this idea. (Author)
