Radar Refraction Computations Using Digital Vertical-Incidence Ionograms.
Abstract
Highly accurate radars, such as those used in space-track and missile-tracking applications, may have a need for real-time radar refraction corrections. This requires the handling of large amounts of data which is a cumbersome and time-consuming effort. Real-time ionospheric-refraction correction requires the availability of real-time ionospheric profiles. This report describes a technique to obtain radar refraction-corrections and excess angular-phase-paths, in near real-time. This technique is an extension of the automatic digital-ionogram processing technique. Examples are given to show the variation of the radar refraction correction with operating frequency and zenith angle for several ionospheric true-height profiles.
