Abstract

This work presents a time-frequency signal analysis framework for the modeling and simulation of GNSS-based environmental surveillance monitoring (ESM) applications. The framework is based on an enhanced version of SIRLAB, a signal representation framework developed for the analysis of environmental acoustic signals. This new time-frequency signal analysis framework has been successfully used in the modeling and simulation of GNSS receiver signals to study signal propagation effects as well as local interference signal effects. The framework has been also successfully used for the characterization of GNSS channels as time-frequency (TF) multiple input single output (MISO) channels.
