In a typical field artillery setting, sound ranging is the only available passive target acquisition device. This involves the use of six acoustic microphones placed in a near linear array. The accuracy of the location of enemy artillery depends on many factors. Two major contributors are the timing data obtained via these microphones and the ability to estimate existing meteorological conditions. In this study the interrelationships between timing and meteorological are investigated from both an analytic and a numerical point of view. It is shown that errors in temperature act as bias errors in timing and are nearly linear functions of the distance between the source and the midpoint of the array. Errors in wind however provides a more complicated situation.
