“…To translate range-azimuth-height measurement to the common stereographic plane where all bias calculations are performed, a non-linear coordinate transformation method [22,23] is used. Although [11] proposes the use of ECEF coordinates for bias estimation, from our experience stereographic transformations and related linearisations can be successfully used for network coverage up to 5.000 km.…”

Current bias estimation algorithms for air traffic control (ATC) surveillance are focused on radar sensors, but the integration of new sensors (especially automatic dependent surveillance-broadcast and wide area multilateration) demands the extension of traditional procedures. This study describes a generic architecture for bias estimation applicable to multisensor multitarget surveillance systems. It consists on first performing bias estimations using measurements from each target, of a subset of sensors, assumed to be reliable, forming track bias estimations. All track bias estimations are combined to obtain, for each of those sensors, the corresponding sensor bias. Then, sensor bias terms are corrected, to subsequently calculate the target or sensor-target pair specific biases. Once these target-specific biases are corrected, the process is repeated recursively for other sets of less reliable sensors, assuming bias corrected measures from previous iterations are unbiased. This study describes the architecture and outlines the methodology for the estimation and the bias estimation design processes. Then the approach is validated through simulation, and compared with previous methods in the literature. Finally, the study describes the application of the methodology to the design of the bias estimation procedures for a modern ATC surveillance application, specifically for off-line assessment of ATC surveillance performance.

“…When we translate this measure to the stereographic plane, we use a quite exact non-linear coordinate transformation method like the one used by Paradowski and Kowalski [6]. This method implements a function we call f Ra dar{')-So, to project error terms into the stereographic plane, we make a first-order approximation of this transformation, and have…”

“…Some of its features are that directions from the projection point are true, scale increases away from the projection centre and the projection point cannot be plotted as it is located at the infinity. All these features make this projection very suitable for its use in the ATC domain [Paradowski 1998].…”

he increasingly widespread need for assessing the performance of systems in order to guarantee a certain quality of service (QoS) is fostering the appearance of tools in charge of performing this assessment, which are additionally required to be efficient both, from the point of view of the use of resources, not only material but also immaterial, as well as from an economic point of view.The air traffic management (ATM) environment, which is the field in which this thesis is developed, also reproduces this established trend for several decades now. Research and development programmes aiming at the evolution of the systems in charge of air traffic management, such as the European one, i.e. SESAR, already foresaw since the beginning an evolution in the way of managing air traffic from what was or continues to be an airspace-based management, towards what should be a trajectory-based management, whose next milestone would be the incorporation of the performance level into the service provision to aircraft and airlines, that is, to airspace users. This performance level is understood not only from the point of view of the service customer, that is, the airspace users, but also from the side of the service provider, that is, from the entities known as air navigation service providers (ANSP).The performance level offered by both parties will ultimately determine which servicesand with what level of quality -can be requested by users and offered by the infrastructure put in place by the ANSP. Within the services offered by air traffic management, this thesis focuses on those related to the provision of air traffic control, i.e. those related to ensuring adequate separation of aircraft between each other and with respect to the terrain. Given the importance of this task, it is necessary not only to evaluate the performance of the systems responsible for providing these services, but also to continuously and, if possible, automatically monitor them to ensure that they are working in optimum conditions to guarantee the efficiency and safety of operations.Within the different domains that support the provision of air traffic management services (CNS/ATM), the one that focuses the attention of this thesis is surveillance (S). Specifically, it is the performance evaluation of the surveillance chain what keeps all the focus of interest. This chain ranges from the sensors that detect the targets, e.g. aircraft or airport vehicles, to the presentation of data on the screens that show the situational awareness picture to the controllers, also including communications networks and systems (e.g. routers or gateways), tracking systems and lastly, performance evaluation tools.This thesis begins (Chapter 1) with a top-down approach that starts from the concept of air traffic management and goes down to the field in which all the research is developed, which is known as the surveillance function. Its elements and systems are presented and the relationship between them is established. This function is usually divided into what is known ...
