Modular covert remote electronic warfare simulator

In a field test system having a plurality of “victim” antennas and an equal plurality of associated “victim” receivers, means for generating and transmitting a desired signal free of jamming effects, and means for generating and transmitting one or more radio frequency control signals which represent one or more predetermined jamming threats in either or both of the low and mid bands, an apparatus for electronic warfare signal simulation comprising:

• low band coupling means adapted to be connected between one of the plurality of “victim” antennas and its associated “victim” receiving apparatus for coupling off control signals representing jamming threats in the low band from the received signals and allowing the desired signal to pass with minimal perturbation;
• mid band coupling means adapted to be connected between another of the plurality of “victim” antennas and its associated “victim” receiving apparatus for coupling off control signals representing jamming threats in the mid band from the received signals and allowing the desired signal to pass with minimal perturbation;
• control means for controlling the elements of the simulation apparatus;
• a plurality of simulated jamming signal means connected to the control means, each simulated jamming signal means for generating a simulated jamming signal having a waveform representative of the jamming threat represented by a respective control signal;
• receiving means connected to the control means and to the low band and mid band coupling means for receiving the plurality of control signals from the low band and mid band coupling means and measuring the power level of each control signal to determine the level an actual jamming signal from the corresponding jamming threat would have had;
• and
• band select means connected to the control means, the simulated jamming signal means, and the low band and mid band coupling means, for receiving the simulated jamming signals, translating the frequency of each simulated jamming signal to the frequency of the jamming threat to which it corresponds, setting the level of each simulated jamming signal to the jamming level determined for its control signal, replicating the “victim” antenna gains, feeding the modified simulated jamming signals through the low band coupling means together with the desired signal to the “victim” receiver associated with the one “victim” antenna, feeding the modified simulated jamming signals through the mid band coupling means together with the desired signal to the “victim” receiver associated with the other “victim” antenna, and feeding the modified simulated jamming signals together with the desired signal to the remaining “victim” receivers.
