Emulation involves the generation of real signals to be received by a receiving system, or by some part of that system. This is done either to test the system (or subsystem) or to train operators in the operation of the equipment. In order to emulate a threat emission, it is necessary to understand all of the elements of the transmitted signal and to understand what happens to that signal at each stage of the transmission, reception and processing. Then, a signal is designed to look like the signal at some specific stage in the path. That signal is generated, and injected into the process at the required point. The requirement is that all of the equipment downstream of the injection point think it is seeing the real signal in an operational situation.
