Experimental Studies on Microwave Gunn Oscillator Based Modulator-demodulator Systems with Chaotic Modulating Signals

摘要：

　　A technique of chaos-based communication using X-band microwave frequency channel has been experimentally studied.Chaotic signals of lower radio frequency(RF)region(~200kHz)is used to angle modulate an X-band Gunn Oscillator(~10GHz)by a bias tuning technique.The modulated microwave signal is detected in a phase discriminator type demodulator designed using an injection synchronized Gunn oscillator.Obtained results indicate that information bits encoded on low frequency RF chaotic signals could be transmitted and received through a microwave channel by an adequate modulation-demodulation process.
