The development and performance of a complete oblique ionogram autoscaling and inversion algorithm is presented. The inversion algorithm uses a three layer quasiparabolic model of the midpoint electron density profile. The inversion process is formulated as an optimization problem that uses a two-stage simulated annealing optimization algorithm. The inversion algorithm was tested using both synthetic data and oblique ionogram data obtained for a link between Goose Bay and Wallops Island. The results of the inversion were compared with midpoint electron density profiles recorded at the Maine OTH radar.
