Dynamic features of autodyne signals

Abstract

On the example of classical single-circuit oscillator influenced by reflected signal, a solution of system of differential autodyne equations is obtained by the high-order quasi-static approximation method for the general case of arbitrary delay time of the reflected signal, fast motion of a point-sized reflecting object, and inertia of the oscillator itself. The special features of forming the autodyne response are considered with allowance for the oscillator inertia and its internal parameters, including anisochronous and non-isodromic properties, and dependences of the signal waveform, constant component, and nonlinear distortion coefficient on the distance and the direction of object motion are established. © 2013 Springer Science+Business Media New York.
