WebAug 26, 2024 · “An incoherent scatter radar actually allows you to detect a bunch of characteristics of the atmosphere and its plasma that no other technique allows you to do, except launching rockets through it,” he told news.com.au. “In terms of military use, my understanding is that these facilities for the most part are used for scientific research. WebAn incoherent scatter radar (ISR) system is a radar system that can measure the altitude dependence of a set of ionospheric observables. This set includes the electron density, the electron and ion temperatures, and the ion bulk drift velocity.
