    Abstract: A technique for simulating various signals, such as from radar emitters, in a broad frequency spectrum by generating at any given instant only those of the signals that affect a receiver which is tuned to a particular bandwidth. As the receiver is tuned to a new bandwidth, the simulating system responds by quickly generating any signal or signals that exist in the new bandwidth.
