Patent ID: 8175512

Claim:
A system for jamming radio frequency communications comprising: a radio frequency generator for producing a radio frequency signal; a transmit antenna for transmitting a radio frequency signal; a receive antenna for receiving a radio frequency signal; at least one an antenna unit, the antenna unit having a receiver having an input and an output, the input of the receiver coupled to the receive antenna, an amplifier having an input and an output, the input of the amplifier coupled to the output of the receiver, and a transmitter having an input and an output, the output of the transmitter coupled to the transmit antenna; a signal mixer having inputs and an output, the output of the amplifier coupled to one of the inputs of the signal mixer and the output of the radio frequency generator physically coupled to another input of the signal mixer and the output of the radio frequency generator also coupled to the input of the amplifier; a detector coupled to the output of the signal mixer for detecting a potential radio frequency threat signal; and a blanking pulse generator coupled to the transmitter for temporarily silencing or blanking the transmitter so that the transmitter does not output a signal to the transmit antenna.
