Abstract

This repository contains Jupyter notebooks, Python libraries, and supporting materials for generating all figures in the Frontiers manuscript on HF Time Difference of Arrival (TDOA) measurements from chirp sounder data. The analysis uses cross-correlation techniques to detect chirp signals in WAV recordings and extract TDOA measurements between different ionospheric propagation modes. These TDOAs are then converted to ionospheric layer heights using a spherical Earth virtual height model and compared with ionosonde measurements.
