Abstract : A method is presented which permits the measurement of mutual impedance between electroexplosive devices and radio, radar, or other radio-frequency generators aboard ship. A prediction method was developed which reduced the entire electrical complex between the EED and sources of electromagnetic energy to an equivalent electrical circuit. Initially, it was extremely time consuming to make the measurements and computations necessary to define all elements of the equivalent electrical circuit. Gradually, it became obvious that it was unnecessary to make many of these measurements and computations. The equivalent circuit methods of prediction have the advantages of negligible instrument perturbation and the use of sensitive instruments which permit extremely low power radiation and, consequently, have more freedom in frequency usage.
