THE PRINCIPLES OF ARTIFICIAL GLINT JAMMING (CROSS EYE)

Abstract

Two suitably phased, coherent jamming sources, of approximately equal amplitudes, located on the extremites of a target, can introduce considerable angular errors or glint into radars tracking that target. A theoretical method of analysis is presented whereby the effect on any tracker of two sources of any amplitude and phase relationship can be computed. The tactical effect, on various weapon guidance systems of an artificial glint jammer installed as a self-protection device in a single target aircraft, is discussed. It is shown that, in certain circumstances, a useful effect could be obtained with phase tolerances that correspond to attainable engineering limits. A practicable artificial glint jammer circuit, using a single RF tube and a ferrite phasing device, is proposed.
