Abstract:
1. A system for jamming radio frequency communications comprising: a radio frequency generator for producing a radio frequency signal; at least two transmit antennas for transmitting a radio frequency signal; an antenna unit having at least two amplifiers, each amplifier having an input and an output, and at least two transmitters, each transmitter having an input and an output, the output of each respective amplifier coupled to the input of each respective transmitter and the output of each respective transmitter coupled to its respective transmit antenna; and a programmable feed device coupled between the radio frequency generator and amplifier of the antenna unit, wherein, the radio frequency generator provides the radio frequency signal modulated upon a sweeping radio frequency carrier signal, wherein the frequency transmitted from at least one of the transmit antennas sweeps forward from a first low frequency to a second higher frequency and then sweeps back from the second higher frequency to the first lower frequency.
