Single Emitter Analysis Model (SEAM)
Overview

SEAM is a single-emitter analysis program that supports user-interactive computations and automated unit conversions in direct and inverse modes. The user has the option to specify the emission level as an emitter power or as field strength at a reference distance selected by the user. The direct mode estimates received signal levels (power, voltage, power flux density, field strength) at a propagation distance specified by the user. The inverse mode estimates the propagation distance required to meet a received threshold specified by the user, up to 500km distance limit. The user selects between free space or the smooth earth (IPS) propagation model for the path loss versus distance conversion. All unit computations are performed automatically. The output data display is presented in both dB and non-dB units, using scientific notation for the latter.
