Intrasystem Analysis Program (IAP) structural design study

The Intrasystem Analysis Program is a collection of computer codes used in analyzing the electromagnetic compatibility of aircraft, space/satellite, and ground-based systems. The IAP is reconsidered here in terms of an overriding framework. The concept of a procedure is introduced whereby emitter, receptor, and coupling models are grouped and interfaced for efficient use in EMC analysis. All aspects impacting the construction of a procedure are considered in detail. These include data; task; systems equations; emitter, receptor, and coupling models; computer resources; accuracy; and intended user. The attributes of many existing, or soon to be available, coupling models are tabulated for ready reference during the construction of procedures. The wide range of problems amenable to these coupling models is made apparent through grouping into 'basic' and 'combined' categories.
