Radiative transfer equations and analytical multiple scattering theory of waves have been applied to microwave remote sensing since the 1980’s. With the advance of computers and computational electromagnetics, Numerical Maxwell Model of 3D simulations has gained importance. In this webinar, we start with dense media full-wave simulations. Next, we describe 3D simulations of rough surface scattering.

Traditional active radars transmit a powerful electromagnetic pulse and record the echo's delay time and power to measure target properties of interest, such as range, velocity, and reflectivity. Such observations are critical for investigating current and evolving conditions in extreme environments (i.e., polar regions and planetary missions); however, existing radar systems are resource-intensive in terms of cost, power, mass, and spectrum usage when continuously monitoring large areas of interest. I address this challenge by presenting a novel implementation of passive radar that leverages ambient radio noise sources (instead of transmitting a powerful radio signal) as a low-resource approach for echo detection, ranging, and imaging.

Join the Award Ceremony of the EO4SDG Mini-projects, and the Earth at Risk image contest organized by the IEEE Geoscience and Remote Sensing Society. The winners of the two competitions will get the chance to present their proposals and talk about the stories behind their outstanding EO data images followed by a Q&A session.

The presentation will summarize the potential advantages and applications of 500 1400 MHz microwave radiometry for Earth observation and review recent experiments and demonstrations of these concepts. The presentation will also describe remaining questions and challenges to be addressed in advancing to future spaceborne operation of this technology along with recommendations for future research activities.
