a first transmitter that transmits an information carrying signal to a target receiver;
a second transmitter that transmits a first jamming signal to the target receiver, the second transmitter positioned at a first predetermined distance from the first transmitter; and
a third transmitter that transmits a second jamming signal to the target receiver, the second transmitter positioned at a second predetermined distance from the first transmitter,
wherein the first transmitter, the second transmitter and the third transmitter each transmit their respective information carrying signal, first jamming signal and second jamming signal such that the information carrying signal, first jamming signal and second jamming signal are interleaved when received by the target receiver.
