1. A jamming device comprising:
- a periodic signal generating circuit configured to generate a periodic signal;
a noise generating circuit configured to generate a noise signal; and
a sweep-signal generating circuit coupled to the periodic signal generating circuit and the noise generating circuit, the sweep-signal generating circuit being configured to generate a frequency-sweep signal based on the periodic signal and the noise signal, and the sweep-signal generating circuit comprising;
a level shifter coupled to the periodic signal generating circuit and the noise generating circuit, the level shifter being configured to superimpose the noise signal on the periodic signal to generate a superimposed periodic signal; and
a voltage-controlled oscillator (VCO) coupled to the level shifter and configured to generate the frequency-sweep signal according to the superimposed periodic signal.
