This paper explores using geolocation techniques in military applications, focusing on optimizing flight maneuvers for aerial platforms to locate ground Radio Frequency (RF) threats accurately. The importance of observing the threat from wider angles to mitigate geolocation errors is emphasized. Through the analysis, the aim is to determine the optimum heading angle that enhances the precision of the geolocation technique. Determining optimal heading angle allows for an optimized route, leading to more accurate localization of RF threats. Significant improvements in geolocation accuracy were achieved by implementing route optimization, mainly by maximizing the difference between the direction of signal arrival data collected by the platform. These strategies are crucial in reducing geolocation errors and enhancing threat detection and positioning capabilities in military operations.
