“…It is assumed that accurately determining the AOA of ADS-B signals is feasible based on the research conducted by Reck et al in [2], [3], [4], [5], [6], [7] and by Faragher in [8]. Both of these researchers, whose publications are summarized in Section 3.0 -Review of Literature, empirically demonstrated that the AOA of ADS-B data can be determined at a stationary antenna with a Root Mean Square Error (RMSE) of less than 1 degree.…”

“…The EKF seeks to estimate the state and covariance of a non-linear discrete time process defined by the stochastic difference equation in (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15), given a measurement of the form expressed in (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16) [24].

“…It should be noted that f and h are vectors, where each element defines the non-linear equation required to calculate the corresponding state/measurement value. This is expressed in the expanded equation forms of (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15) and (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)…”

“…That work proposes the use of Genetic Algorithms (GAs) to obtain an optimal distribution (system geometry) of a fixed number of MLAT ground stations, but only taking into account the LoS and the DOP. The possible system improvement with other kinds of measurements, such as RTD [2,7] or AOA [2,8], is also proposed and fully described. Another important aspect is that the DOP only reflects the errors due to the spatial distribution of the stations, regardless of other important sources of errors (e.g.…”

In this paper, an effective procedure to emplace standard and enhanced mode-S multilateration stations for airport surveillance is studied and developed. This procedure is based on meta-heuristic optimization techniques, such as genetic algorithm (GA), and is intended to obtain useful parameters for an optimal system configuration that provides acceptable performance levels. Furthermore, the procedure developed here is able to evaluate and improve previous system designs, as well as possible system enhancements. Additionally, the design strategies to be used along with the procedure proposed here are fully described. Parameters such as the number of stations, the system geometry, the kind of measurements to be used, and the system accuracy are obtained taking into account the basic requirements such as the Line of Sight, the probability of detection, and the accuracy levels.

“…Regarding to the hardware based solutions, one of these is by adding more stations, i.e., usually the problem of ill-conditioning is found for situations with a number of stations smaller than seven or eight [20]. Another one is by adding new measurement capabilities to the system, such as the AOA [20], [115] or RTD [20], [116], i.e., in a numerical sense, adding new measurements means to improve the corresponding data model and, therefore, to change the ill-conditioned coefficient matrix into a well-conditioned one. However, all these solutions, although are efficient options, require in many cases significant money investments.…”

New Strategies to Improve Multilateration Systems in the Air Traffic Control

This thesis is focused on the Mode S Multilateration (MLAT) systems for the Air Traffic Control (ATC) operations, specifically on their layout design and on the process of cooperative targets localization performed by them. It addresses the development of new design and localization strategies. The design strategies are based on the application of metaheuristic optimization techniques, whilst the localization ones are based on the application and combination of regularization methods along with some current localization algorithms.The design strategies are composed of an effective, general procedure to emplace both the standard and enhanced MLAT receiving stations on a surveillance volume, and a set of design strategies to be used with such a proposed procedure. This procedure uses the metaheuristic of Genetic Algorithms (GA), and is intended to obtain useful design parameters that allow optimal system configurations that provide suitable performance levels. Furthermore, the procedure developed in this thesis is able to evaluate and improve previous system designs, as well as possible system enhancements. For this context, we overcome several issues like the lack of a general model that relates the system performance parameters with those ones that can be simulated on a computer, the setting of the design problem as a computer optimization one, the development and application of the numerical tools to analyze and evaluate the MLAT systems performance, the complexity evaluation of the resulting computer optimization problem, and the application and modification of the GA components for solving such a optimization problem. To validate the contributions in this context, some simulations are performed on a real airport scenario.The localization strategies are composed of a set of developed regularized location estimators, a set of developed additional improvements, and the use of some current localization algorithms. These strategies can be used for both surface and wide areas surveillance, and solve some practical problems like the loss of position accuracy when using a small number of stations, or viii Abstract for small areas where the stations are close to each other (e.g., airport surface surveillance), and the mitigation of some errors due to multipath effect. Moreover, the proposed localization strategies are found to be highly statistically and numerically efficient, in contrast to current ones that are efficient in only one sense (i.e., statistically or numerically). For this context, we overcome several issues like the identification and evaluation of the numerical causes of the above mentioned problems, the analysis of the current localization algorithms, the adaptation of the regularization methods theory for solving the localization problem, the development of some numerical additional tools that allows the real time implementation of such proposed algorithms, and the combination of the current algorithms with the proposed ones. To validate the contributions in this context, some simulations wit...
