This report reviews work done in gaining some familiarity with methods of passive geolocation, and a search for rules of thumb that might tell us how to optimize the geolocation for a given scenario. We first cover the main approaches to collecting angle of arrival data and point out typical accuracies. Following this is an account of the mathematics used to analyze this data to produce an estimate of an emitters location. We then give an overview of some of the literature, and finish by demonstrating a Matlab programme that runs several geolocation algorithms. Simple rules of thumb that specify how to fly a baseline and take data, so as to maximize the accuracies of the different techniques, do not appear to be readily derivable.
