WebSEC has developed an image processing technique called the Expert System for Ionogram Reduction (ESIR), which has been patented [Sojka et al. 2009]. This software was developed specifically to recognize and invert an ionogram from a photographic image, producing an equivalent ionospheric electron density profile. WebThe extraction of ionospheric parameters from ionograms is undoubtedly an indispensable, time-consuming and laborious work without which the ionospheric sounding itself would de meaningless. Several approaches were proposed a11d tested so far to save time and labor for the reduction of ionograms.
