From: Novel maximum likelihood approach for passive detection and localisation of multiple emitters
An exemplar scenario with four target events and three sensors that provide hybrid AOA/TOA measurements. Shown are target events (marked by triangles) and the sensors (marked by diamonds); along with AOA measurements (black lines) and DDOA measurement hyperbolae (grey lines). Also shown is the likelihood map, with dark regions showing a normalised overall measurement likelihood close to unity, and white regions showing a normalised overall measurement likelihood close to zero. It is noted that this likelihood map is not calculated by the TALA and is shown for illustrative purposes only
