A linear-FM signal generator on the basis of a recirculator

The paper describes a linear-FM oscillator constructed on the basis of a recirculator with spatial-temporal shift in the feedback circuit, which allows the generation of signals with high linearity of frequency change. The frequency-deviation products of the generator are associated with a duration exceeding 10,000. A simplified circuit diagram of the generator is presented including a radio pulse generator, a mixer, a heterodyne, a delay line, and an AFC system.
