Remote sensing and wave propagation is a broad discipline examining the interaction of electromagnetic fields with material media. It encompasses research areas such as aeronomy, geosciences, atmospheric science, remote sensing, wave propagation, electro-optics, plasma science, signal processing, and communications.
Researchers use radar, LIDAR, and passive optical techniques to probe the Earth's upper atmosphere to learn its physical, chemical, and dynamic processes. Wave propagation studies are performed with MF (medium frequency) radar, meteor radar, and incoherent backscatter radar.
Field campaigns include the use of spacecraft and aircraft platforms as well as a number of ground stations in the Antarctic, Greenland, Peru, Australia, Urbana, New Mexico, and Hawaii.
