Segmentation of the F2 Leading Edge in a Backscatter Sounder Ionogram (opens in new tab)

Backscatter sounder (BSS) systems colocated with over-the-horizon radar (OTHR) can be leveraged to provide a near-real-time characterization of the ionospheric propagation conditions to aid the OTHR surveillance mission. Ionogram inversion can be performed using features derived from a backscatter ionogram to infer the optimum OTHR operational parameters and to enable the geolocation of the detected targets. In this article, we demonstrate the application of a deep learning segmentation model...
