The Tactical Electronic Warfare Systems (TEWS) group within the Communications and Navigation Electronic Warfare (CNEW) section at DRDC Ottawa is focused on investigating and testing next-generation emitter geolocation techniques for the Canadian Forces. To that end, and as part of the Klondike Technology Demonstration Program (TDP), many geolocation algorithms have been developed using different techniques and several measurement campaigns have been conducted to produce data which could be used to validate the algorithms. Previously, each algorithm was tested independently, generally by the scientist that developed it, and each scientist had a different methodology and set of assumptions. This made comparing algorithm performance from different researchers very difficult. The GeoLocation Algorithm Benchmark and Testbed (GeoLAB) tool fills this gap by providing the ability to easily test new algorithms and fairly compare them with other approaches/algorithms in a single universal easy-to-use platform. GeoLAB, which was developed in MATLAB and has an easy-to-use graphical user interface, allows an arbitrary number of algorithms to be simultaneously run on a dataset (simulated or measured data) and provides many options as to how the calculations will be conducted and how the results will be displayed, including a Google Earth display option. It will be used to identify the most suitable geolocation method for the Klondike TDP and select the best performing algorithms for futur
