A computational study and design of a body-borne direction finding (DF) system is presented in this paper. A baseline model of a two-sensor DF system and human body is established. Computer models are validated using a prototype human body phantom. A sensitivity study is performed on seven model variables to identify system stability and establish thresholds for direction finding. A discussion is presented on how these thresholds may be used to generate a direction finding solution from the data collected by the system.
