Abstract

A system for jamming continuous wave radar type proximity fuzes used on surface-to-air missiles where the fuze requires an increase in return signal power level and a rapid frequency change for detonation. The system basically includes a receiver, amplifier, and transmitter. A received fuze signal is filtered and square wave modulated then sent to a first traveling wave tube for amplification. The signal is then amplified again by a second traveling wave tube which is modulated by a transit time modulator which continuously varies the phase shift through the tube in a linear fashion. The linear variation in phase shift is the equivalent of a displacement in the frequency signal being amplified. The signal is then reradiated to the missile giving the fuze a target sensing causing it to predetonate.
