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.

LuTan-1 is an innovative spaceborne Synthetic Aperture Radar (SAR) mission with bistatic interferometry capability. In this talk, I will provide an overview of the SAR system of LuTan-1, describe the technical challenges occurred during the development such as phase synchronization, range ambiguity and non-linear FM waveform, and present the preliminary LuTan-1 results from the bistatic imaging, DEM generation from bistatic interferometry, deformation mapping from mono-static interferometry and ground target classification from the unique compact polarization.

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.
