Abstract : The Intrasystem Electromagnetic Compatibility Analysis Program (IEMCAP) is a system level, computerized analysis program which may be used in analyzing electromagnetic compatibility (EMC) for aircraft, spacecraft or ground stations on both present and future systems. The objective of this effort was to increase the prediction capability of the IEMCAP. The defined tasks to obtain the new capability are the following: (1) development of a frequency dependent power gain antenna model for IEMCAP; (2) modify IEMCAP to predict the electromagnetic (EM) interference for those devices whose compatibility is not related to average power; (3) implement within IEMCAP a mathematical model(s) to predict the degradation to receptors of EM energy, caused by spurious signal products generated at an emitter, a structural nonlinearity (i.e., in the transmission path), or in a victim receptor (i.e., signal harmonics, intermodulation, cross modulation, desensitization, gain compression/expansion and spurious responses); and (4) modification of the modeling procedure for a port's emission and/or susceptibility. Upon completion of the above modeling effort, the developed models were to be coded and interfaced with the existing IEMCAP.
