Abstract:
In an active RF missile having at least one antenna element, an autopilot and a seeker containing therein a first generator for generating a first waveform for tracking targets, the missile having a priori data relative to the range to the target upon being launched on its flight toward the target, an in-seeker jamming device for countering active protection systems that protect the target, said in-seeker jamming device comprising: a second generator residing in said seeker, said second generator generating a second waveform designed for jamming said active protection system; a means for selecting waveforms, said selecting means being coupled to said first and second waveform generators and motivating said generators such that only one of said generators is engaged to produce its corresponding waveform at any given moment; an amplifier; a first switching means coupled between said first generator and said amplifier; a second switching means coupled between said second generator and said amplifier, each of said switching means cooperating with said selecting means to provide a signal path between its corresponding generator and said amplifier whenever said corresponding generator is engaged, thereby enabling said amplified waveforms to travel from said amplifier to said antenna element and be radiated from said antenna element for ultimate jamming of said active protection system.
