Descripció del contingut i pla d'activitats:
El TFG consistirà en la detecció i seguiment de drons mitjançant tècniques no col·laboratives basades en la mesura dels senyals emesos pels drons en estacions terrestres fixes, que estaran sincronitzades mitjançant receptors GPS, i que determinaran la seva posició i trajectòria mitjançant tècniques de triangularització i multilateració.
 
Overview (resum en anglès):

Currently, drone detection is essential for restricted airspace. Their small size and high maneuverability pose a threat to airports, as they can cause significant damage to aircraft. In addition, it is important to know the current position of the device. They could paralyze the entire airspace activity for several hours and cause millions of dollars in economic losses for all companies. An illustrative example is 29/08/22 in Barajas¿ airport, where a drone allegedly entered one of the runways and at least seven planes had to be diverted.

The main idea of this project is to propose a solution to the above problem. Since both time and resources are limited, this work will focus on developing a system capable of detecting the presence of a single drone and its position.

The work is divided into 4 chapters. The first chapter presents the theoretical research necessary to fully understand how the system can achieve its goal. The concepts of mul- tilateration (MLAT) and cross-correlation are introduced. In chapter 2, a scheme for the construction of a system is proposed and the functionality of the Matlab program is ex- plained. This program is created to simulate different scenarios and compare the results. In chapter 3, using the program presented above, a detailed study of the influence of each block on the final result of the system (target position) is performed. The following are ex- amined: different scenario setups and signals, the influence of different sampling rates on the final error, different TDOA algorithms, etc. Chapter 4 represents the culmination of the work done up to this point. The developed program and the study carried out in chapter 3 have allowed us to propose a hardware solution that is justified in terms of specifications, performance, and cost to achieve the objective of this thesis. Finally, the conclusions drawn from the project¿s development and considerations for future research are presented.
