Radio frequency interference detection and mitigation techniques for navigation and Earth observation

Fri, 09 Nov 2018 00:00:00 +0000

Abstract & Overview

This PhD thesis is devoted to the design, implementation, and experimental validation of innovative Radio-Frequency Interference (RFI) detection, localization, and mitigation countermeasures in the fields of Microwave Radiometry (MWR), Global Navigation Satellite Systems (GNSS), and GNSS-Reflectometry (GNSS-R). It completes the development of the MERITXELL multi-frequency radiometer, introduces the Multiresolution Fourier Transform (MFT) mitigation algorithm, proposes the Generalized Spectral Separation Coefficient (GSSC) metric for GNSS-R under interference, and presents the patented FENIX real-time pre-correlation anti-jamming architecture (US Patent US9596610B1), demonstrating up to 30 dB of jamming resilience across GPS L1 C/A, GPS L2C, and Galileo E1OS signals. Awarded Best PhD Thesis 2018 by the IEEE Geoscience and Remote Sensing Society (GRSS) Spanish Chapter.

Implementation of Radio-Frequency Interference Detection and Mitigation Algorithms for Communications and Navigation

Tue, 01 Jan 2013 00:00:00 +0000

Abstract & Overview

Radio-Frequency Interference (RFI) signals are undesired signals that degrade or disrupt the performance of wireless communications and satellite navigation receivers. This Master Thesis presents the design, real-time FPGA hardware implementation, and experimental validation of digital signal processing algorithms for the detection and mitigation of continuous-wave, chirp, and pulsed radio-frequency interference in Global Navigation Satellite Systems (GNSS) and passive microwave remote sensing receivers.
