ABSTRACT:
An apparatus for use in controlling a simulated target position in a millimeter wave, hardware-in-the-loop system includes a pair of horns and a conditioning circuit. The conditioning circuit is capable of generating a pair of output millimeter wave signals, each to be broadcast from a respective one of the horns, the output millimeter wave signals being out of phase by a predetermined amount, and capable of attenuating at least one of the output millimeter wave signals to control the position of the simulated target in a first and a second region. A method for use in controlling a simulated target position in a millimeter wave, hardware-in-the-loop system includes generating a pair of output millimeter wave signals that are out of phase by a predetermined amount; attenuating at least one of the output millimeter wave signals to control the position of the simulated target in a first and a second region; and broadcasting the millimeter wave signals. The method and apparatus can be extended to four horns arranged in a quad configuration to control position in two dimensions and can be extended to a test array comprising a plurality of horn pairs and horn quads.
