Abstract : The development of a general digital computer program, is described, to predict the current flowing in an Electrical Initiator (EI), connected to a Receptor circuit of a typical missile system, as a result of the effects of high level radio frequency ambient radiation. The program is based on an analysis of current flow resulting from induced electromotive forces of any value, acting in the series arms of any or all sections of a ladder type network. Included are the effects of mutual coupling from neighboring Interfering circuits, effects of stray capacitance to shields, unbalance, and leakage of electromagnetic energy through apertures in the missile metallic shielding. The electrical length of the network sections are taken sufficiently short to allow lumped values of series and shunt impedances to be used, such that the networks are equivalent, for all practicable purposes, to transmission lines with distributed impedances. The general program is written in FORTRAN IV language for IBM 7090 or 7094 computers. The standard 32K storage is sufficient for about 40 Interfering lines coupling into the Receptor line, each having up to 150 network sections.
