Generation of Ultrawideband Chaotic Radiopulses

In this work a possibility of generating chaotic pulses by means of parameter modulation of chaotic oscillator is demonstrated. Chaotic oscillator with 2.5 degrees of freedom and transistor as an active element is taken as a model. It is shown that periodic stimulation of such system allows to generate chaotic pulse stream, the duration of chaotic pulses, their duty cycle and their waveform can be widely varied by suitable choice of frequency of exciting force and bias voltage.
