Abstract

A method and apparatus for providing a radar jamming signal by simultaneously frequency-modulating a voltage-tunable oscillator with a large-amplitude, periodic, sawtooth waveform and a small-amplitude random waveform. The periodic, sawtooth modulation produces a series of radio frequency spectral lines (subcarriers) of nearly uniform amplitude over a frequency range proportional to the peak-to-peak sawtooth amplitude. The spacing between adjacent subcarriers is equal to the fundamental sawtooth frequency. The secondary random modulation added to the primary sawtooth modulation produce simultaneous, random, frequency modulation of each of the subcarriers created by the primary modulation.
